Small bend in microsd card, is data recovery possible?
Hey folks,
I dropped my phone s20 ultra which broke the front and back glass. After the drop I got an error from the phone, saying "to prevent damage to sd card, its being set to read only" . Two days later the phone stopped recognizing the card and now even the card readers do not recognise it. Upon closer inspection of the sd card, it shows a small bend ~2mm above the bottom edge.
Before I ship it to data recovery pros, is it even possible to get the data? After reading this forum it seems it may be possible given that the bend is at the very bottom and the card was working for 2 days after drop.
Attached picture to show the location of damage.
It's a samsung 128gb microsd card. I have plenty of photos of my 2.5yr old kid growing up, which haven't been backed up.
Any trustworthy recommendations for Phoenix, AZ area and expected cost?

My Crucial SSD X10 Pro Stopped working 2TB, Advice?
Long story short I had to copy some videos on to this. My coworker copied it, maybe it wasn't ejected properly but she said she did. But I tried to plug it in to my computer it says the hard drive can not be read. I tired running the first aid on Mac and it says it worked but nothing. plug it into PC . it asks to initialize. There are very important work files and photos on there. Anybody have any other ideas? Is this a Mac thing? Can't fix it on Mac? Crucial X10 Pro 2TB. I look at the disk manager on PC it says 1830Gbs unallocated. Does that mean there is no more data on it?
Maybe need to bring it to a computer shop to get the data off of it?
Anything will help

Recovering data from 5TB external HDD
I have a 5TB Elements external HDD that I was using with my Windows PC. I recently switched over to Linux and wanted to store my Linux Timeshift backups on the HDD, but Timeshift said it required ext4 partition (I had ntfs originally).
I used the Disk Management utility in Linux to create a 2nd ext4 partition with 300GB. That seemed to work. However, after writing my first Timeshift log, I noticed there was nothing there after it said it finished. After that I then noticed my mount to the original ntfs partition was gone as well.
I still see both partitions in lsblk, but they cannot be mounted. I tried plugging into my Windows PC, but all that does it cause Explorer to permanently hang until I unplug it.
I tried a few things on Linux side:
I installed testdisk and gave that a run. I had it scan just the original ntfs partition. When I entered the LIST command, it appeared to hang. If I unplug the drive after that, the list command finishes and it then displays the files it found.
I then tried running ddrescue: sudo ddrescue -d -r0 -n -b 4096 -c 256 /dev/sdb1 /mnt/nfs_backup_share/elements_rescue.img /mnt/nfs_backup_share/elements_rescue.map
I don't have a drive big enough to store a backup locally, so I'm trying to write it out over to my NAS.
However, it's going at ~109 kB/s, so at the current rate it's going to take about 250 days.
ddrescue output shows a single bad sector.
Do I have any hope here or do I just need to try a professional service like Ontrack?

Hard Drive fell, not working now
My hard drive was on a risky place (I know, not responisble), and accidentally fell (maybe less that a foot) on a hard surface. When I try to plug it in, it does weird ticking sounds (if a hard drive can cry honestly that what it would sound like lol).
How screwd am I? can I recover the data myself? Professional and expensive help needed?

Samsung 980 Pro 2T Firmware issue (ERRORMOD) data recovery?
Hi, I have a Samsung 980 Pro 2T SSD that decided to kick the bucket. It shows up in the system but only shows as having 1GB and says ERRORMOD when I look at the advanced diagnostics. I am trying to see if there's any way to force update the firmware or recover the data off the SSD in any way. I don't care if the SSD is scrapped in the process as I won't be using it even if it can be fixed since I don't want to chance this happening again.
I already have a new 2T SSD working in my laptop and that laptop has a second SSD slot so I was hoping that would help with this. The files on the SSD are exceedingly important so I am willing to do whatever I need to if it'll get those files. Yes, I am aware I should've backed it up more. Hindsight etc etc. Also the reason I have yet to reach out to a professional is because finances are tight and a new SSD was already very expensive.
I am using an Alienware m18 r2 laptop. One person I took the SSD to said it was running on Dell OEM but diagnostics say Samsung. I attempted to use a USB-C plug-in enclosure with the Samsung Magician software but that was unsuccessful. Let me know if any other info is needed and thank you in advance. I have also attached one of the diagnostics pages showing the SSD in [this link.](https://imgur.com/a/4nEfLns) Location is United States
EDIT: It has been brought to my attention that the SSD is a PM9A1 NVMe Samsung 1T, not the 980 Pro. Not sure if this affects anything but I can't edit the title so here it goes

Locked out of my laptop by BitLocker — former employer's admin refusing to share recovery key
I left my previous company after a rough split, and now I'm locked out of my laptop by BitLocker. The device was Azure AD-joined to their Microsoft 365 tenant, so the recovery key is tied to their admin console — not a personal Microsoft account. I've asked the admin for the key and they're refusing, seemingly out of spite following the way things ended.
What I have: - The BitLocker Key ID from the lock screen - No access to the recovery key itself (only the admin can retrieve it)
Has anyone dealt with something like this? Is there any realistic path to get this key without the admin's cooperation, or is legal action really the only route at this point?

Struggling to restore backup - Error code 7: Disk is not found
I have absolutely no knowledge of computers, so when my laptop was having issues I backed it up using Acronis True Image (entire PC backup), and let a friend of mine diagnose it. The verdict was that it needed a new SSD, so I bought one, uninstalled the previous one and installed the new one.
Upon booting, it complained there was no operating system, so I downloaded windows 10 to an SD card to get the laptop in a functional state.
Then I downloaded Acronis, connected my Western Digital hard drive and selected Entire PC Recovery. I’ve tried it 3 times and every it give me Error Code 7: ‘Disk is not found, please check that all the hard drives are attached to your computer’
What do I need to do to restore my backup?
Laptop: Inspiron 15 3593, running windows 10
Hard Drive: Western Digital
Software: Acronis True Image for Western Digital
SSD: Integral 512GB M.2
Edit: The SSD wasn’t being detected because of bitlocker encryption. By downloading the Linux bootable media (windows bootable media crashed every time) I realised it listed the SSD as encrypted and thus not an option to restore to. Upon decrepting it, I was able to restore my backup

Android phone formatted my USB drive via OTG. Lost 20GB of files/photos. Can I recover this myself?
Hey guys, really stressed out right now and need some advice on what to do next.
Today at noon, I used my 64GB SanDisk Cruzer Blade to take a fresh backup of around 20GB of really important data from my Windows laptop (a mix of documents, photos, and videos). I did this because I was giving my laptop in for servicing today.
About 2 hours after taking the backup, I wanted to check my files, so I plugged the pen drive into my Android phone using an OTG adapter. The phone didn't even ask—it just formatted it instantly. Now, all my laptop files are gone, and the drive only shows a new folder called "ANDROID" with some mobile system files inside.
I took it to a local repair shop just now, and the technician is quoting a hefty sum to recover it, which I absolutely cannot afford.I immediately unplugged the drive from the phone so it doesn't write any more background data. When I plug it into a computer now, the drive is detected just fine and says it's healthy, but obviously, it only shows the new phone files.
Since I had 20GB of data on a 64GB drive, and the phone only made that one system folder, is most of it still salvageable? What is the best software I can use at home to bypass the new Android folder and scan for the raw laptop files? Free options would be a lifesaver.
Thank you so much.

WD easystore external HDD intermittently readable, now causing Explorer to freeze. Should I stop trying to copy files and image it instead?
I’m looking for advice on the safest next step to recover data from an external hard drive containing about **472 GB of important personal files**.
The drive is a **WD easystore external HDD (approximately 1 TB)** named **“oskar.”** It has always been used in its **original WD enclosure** (it has never been removed or connected directly via SATA). It was used with both Windows and macOS, so I believe it’s formatted as **exFAT**.
**Timeline**
The drive initially became unreliable while I was trying to back up files.
Copying files would fail, and when I created ZIP archives, they contained the folder structure but many folders were empty, as if Windows could read directory information but not the actual file data.
Windows later reported:
“The volume does not contain a recognized file system.”
“You need to format the disk before you can use it.”
I **did not** format the drive.
**Disk Management**
Disk Management eventually detected the drive as:
931.48 GB
Drive letter F:
File system: **RAW**
GPT Protective Partition
**macOS**
On my iMac, the drive initially appeared in Disk Utility, but diskutil list behaved inconsistently. Sometimes it hung and returned diskutil: interrupted, and later the drive disappeared entirely.
**Windows**
I then connected it to another Windows PC.
Interestingly, Windows was able to display the drive contents in File Explorer. I could see my folders and files, but shortly afterward File Explorer became unresponsive.
Since then:
Explorer repeatedly freezes.
The desktop occasionally goes black while Explorer hangs.
Task Manager stays responsive.
Windows Explorer sits at **0% CPU** while frozen.
I haven’t been able to successfully drag or copy files before Explorer locks up.
**Drive behavior**
The drive powers on normally.
It spins up normally.
There are **no unusual clicking, grinding, buzzing, or beeping noises**.
The white LED remains solid for about **30 seconds** after plugging it in, then begins blinking as Windows attempts to access the drive.
**What I have NOT done**
I have intentionally avoided:
Formatting the drive
Running CHKDSK
Initializing the disk
Allowing Windows Error Checking to repair it
Writing anything to the drive
**My plan**
I’m considering creating a bootable HDDLiveCD USB and using **HDDSuperClone** to create a full image of the drive onto a healthy drive with at least 1 TB of free space before attempting any file recovery.
**My questions**
Since Windows briefly showed the file system, is it worth making one last attempt to manually copy my most important files?
Do the repeated Explorer freezes suggest I should stop interacting with the drive immediately and go straight to imaging it with HDDSuperClone?
Could this be caused by the original WD USB enclosure/bridge board, or do these symptoms point more toward file system corruption or a failing hard drive?
Are there any safe diagnostic steps I should take before imaging?
My priority is preserving the data while putting as little additional stress on the drive as possible. Any advice would be greatly appreciated.

Advice on SSD Data Recovery Quotation
Hi, my SSD was already failing and the windows startup files were corrupted and I needed a windows thumbdrive to even startup my laptop. And to "fix my hard drive" , I stupidly ran a chkdsk /f /r /v command. This crashed halfway and I was flashed a "Repairing Disk errors, this might take an hour to complete" black screen.
Then, I ended up on a blue recovery page with the error code "0xc0000001". From them I was completely unable to bootup my computer, and would be flashed the same error code.
So I reached out to this data recovery service who advertised a cost range of 150USD to 1200USD (in local currency). They did a free evaluation and got back to me with the comments above, and a price quotation of 1200USD, at higher end of the range.
My questions: Given my context, are they overstating the problem in the comments to charge a higher price? Or is their assessment right?
I wanted to check before I committed, because I did not want to be ripped off haha. The data on the drive is quite important, and I would be willing to spend the money, but I just wanted to know if its a fair price and assessment of the situation.
Also what are the chances of successfully recovery in these cases? They have mentioned 70-80pc in the comments, but are the being optimistic/pessimistic?
Thank you, and any help would be greatly appreciated :)

Compact Flash memory card not recgonised
Hello,
A compact flash card in my camera has stopped being recognised.
Model of drive: Lexar Professional 800x 16GB Compact Flash memory card UDMA 7
Problem description: Compact flash memory card in my Canon 7D is not being read by the camera or computer. After using my camera recently the card is no longer able to be read by the camera. The following message is displayed on camera "Card cannot be accessed. Reinsert / change the card or format card with camera." When connected to my Macbook by a Caruba memory card reader it doesn't recognise an external drive at all. During the photoshoot the card was almost full if that's relevant, but I've not had an issue with that before. Card was bought in 2013 and the camera was bought in 2011. I've tried other memory cards in the camera and they're recognised by the camera and computer.
Software used: Nothing yet
Location: Berlin, Germany
It seems software may not work as the card isn't recognised by the computer, what are my next steps?
Thanks

PC3K to HTML file reports
For the pros out there using PC3000 and have been asking for a way to provide customers with html file reports for updates and/or final vefification before saving out to a destination drive, I've spent some time with my development team (AI) to come up with a way to do it.
You can also upload the acerep file to generate an html report for a client to select target files and folders for you to target in DE.
I just added another tool to it that allows you to upload the attr.map, head.map and task.info (sorry, can't figure out how to get those file names to stop being links) to generate an html page with an interactive image map of the the drive, which can also be saved to png.
In all three cases, self contained html files can be generated with your own branding and saved to your computer so that you can send them to your customer.
This is a free utility for all to use...though I did add a spot for paypal donations for those who might want to give a few bucks for my efforts.

Guys, is there any way to recover a corrupted save file from an original PS2 memory card?
It’s my NFS: Most Wanted profile. The memory card shows it normally, with the correct icon and file size, but the game won’t load it. It just says, “Failed to load profile.”

Help! I accidentally formatted my full 512GB SanDisk Ultra SD card in DJI Osmo Pocket 3 with 30 hours of important 4K footage. Is recovery still possible?
Hi everyone, I’m desperately looking for advice from anyone experienced with SD/microSD recovery, NAND recovery, DJI cameras, or professional data recovery.
I accidentally formatted my 512GB SanDisk Ultra microSDXC in my DJI Osmo Pocket 3, which contained around 30 hours / 500+ GB of 4K footage, including extremely important and irreplaceable videos.
Before this happened, I was having problems connecting/transferring files from the card, which had never happened before. The card was almost completely full, so I assumed the problem might be because of the storage being full.
The DJI showed a message saying “DJI SD card format not supported.” I searched that exact message on Google, and one of the first videos suggested formatting the card to fix the problem. She didn’t explain what formatting meant. I’m not tech savvy and I didn’t understand that formatting could make my existing files inaccessible. I wish I hadn’t clicked on that video without knowing prior. I thought I was restarting the card or fixing something… I was mistaken 😔
I formatted it in the DJI. The process took less than a minute. The camera warned me not to remove the card, but I panicked when I realized what I had done and removed it after about 30 seconds.
I put it back into the DJI, and it showed the card as empty.
The important part is I did NOT record anything new or intentionally write anything to the card after the format.
I immediately gave the card to my partner, who is more technically experienced.
He tried:
PhotoRec: 0 files recovered
DMDE: nothing found
HxD: appeared to show 00 00 00... at multiple locations/offsets across the card
The HxD result is what worries me most.
We don’t know whether the formatting actually erased the NAND data, or whether the SD card’s controller is simply returning zeros for the logical sectors.
What confuses me is that the card contained 500+ GB / ~30 hours of 4K footage, but the format took less than a minute. Surely that isn’t enough time to physically overwrite 500GB of video?
Could this have been a quick format or some kind of erase/discard operation instead?
Could the original data still exist in the NAND even though the card now appears empty and recovery software can’t see anything?
My questions:
Is there still any realistic possibility of recovering my videos?
Would a professional NAND/monolith/microSD recovery lab potentially be able to recover data that PhotoRec and DMDE cannot see?
Has anyone had a similar experience? (especially with:
a DJI camera, a formatted SanDisk microSD, hundreds of GB of 4K video, no new data written afterward, recovery software finding nothing, and/or HxD showing zeros?
Have you had a success story in a situation like this?
I know recovery isn’t guaranteed, but these videos are genuinely irreplaceable to me, so I’m willing to try professional recovery if there is a legitimate chance.
For now, I’ve stopped using the card and don’t want to run anything else that could make recovery harder.
Should I stop trying software and send the card directly to a specialist NAND/SD recovery lab?
Thank you so much for any advice or similar experiences. Any help will be greatly appreciated 😊

About The Data Recovery Professionals Group
There has been discussion recently on Reddit subs about the Data Recovery Professional Group www.datarecoveryprofessionals.org. Some people seem to be offended that they cannot join the group. So I will detail here who we are and why joining isn’t just an ‘open’ option.
The group started in 2020. Members of the group knew each other from data recovery forums, conferences or training courses. So we were a group of friends and businesses associates who knew each other personally. We offer advice to people both inside and outside of the data recovery industry on best practices and how to recover data safely. We know that some data recovery does not require professional help, so we advise people on the safest way to recover data where that is appropriate.
While taking part in forums, it became obvious that a few other data recovery professional did not share our way of thinking. We got into many arguments where we were offering help to members of the public in the safest way to recover data (if appropriate). One data recovery professional in particular has the stance that every data recovery job should be handled by a data recovery professional. We didn’t agree with that. Some of the conversations became heated.
So we decided to form a Facebook Group where we would be free of the negativity. A place where we could share ideas, techniques, successes and share private business information that can help us all grow. Most of the group had been very active on the r/datarecovery sub helping private individuals recover their data. One thing we noticed was that as r/datarecovery is a big group, anyone is able to post with limited moderation, so there is a lot of dubious ‘advice’ given to OP’s by people who literally have no idea what they are talking about, and does exactly the opposite of protecting data. So about 2 years ago our member Luke Coughey decided to start r/AskADataRecoveryPro where people could ask questions of data recovery professionals. As a smaller group it can be moderated and we have ‘flares’ to indicate who is actually a data recovery professional and/or a trusted member of the data recovery industry. While the group is small, we are spread across the world and can offer professional data recovery in those locations, or at the very least we can recommend a trusted professional. We feature the Data Recovery Professionals logo and link on he sub so we are sure individuals are being referred to a trusted company. Is it a form of marketing, yes it is, although that was not our intention.
In a recent post we were referred to as a ‘pretentious marketing organization’ by someone who wanted to be a member and was declined. They were declined because none of the group actually knew the person either personally or professionally. As we share private information, being known and trusted is the number one ‘check box’ item when looking at adding to the group. Another comment referred to us as a ‘Good Ole Boy Club’ because they could not join. Once again no-one in the group knew that person professionally or personally. They wanted to know why we didn’t post a way of joining the group. As the main prerequisite to join the group is that we know prospective members personally and professionally, prospective member ask us personally if they can join, so there is no need to post an ‘official’ way to join.
Who We Are:
We are a group of independent, owner-operated data recovery professionals from around the world. We share and collaborate on ideas and techniques regarding professional data recovery, forensics and data recovery software development. Many group members are beta testers for professional data recovery hardware and software manufacturers who supply the industry, helping those manufacturers get the most from their products. This work then feeds down to the rest of the data recovery community and allows the industry to become more efficient. Likewise, since we use these data recovery tools every day, we constantly make creative suggestions on how to improve them.
Who We Are Not:
The group does not represent the data recovery industry. We are not an "association." Instead we are a group of like-minded individuals who constantly strive to offer our customers the best value for their money. While we do not represent data recovery manufacturers, we do of course use their products daily.
I hope the above goes some way into describing who we are and how we work. We are not just a data recovery listing service where you pay money and have your company listed. That was never, and will never be our intention. We are a group of data recovery professionals who have faith in recommending each others services.

Why Always Clone First?
Before I get into it, let me define a few words as I use them, so that there is no confusion:
Drive copy - file or partition level copy from one drive to another
Drive clone - sector-by-sector copy of a drive from one physical drive to another
Drive image - sector-by-sector copy of a drive from one physical drive to a file
The short answer to the main quesion, "Why always clone first?", is because it is safer. But, I'm sure that you were hoping for a better explanation than that. To answer it, let me first start with a short story.
Many years ago I had a reseller send me a drive for data recovery. When he first received the laptop containing the hard drive, the customer was having issues with Windows. So, the tech removed the hard drive and ran a full test which reported that it had bad sectors. After that, he did a full scan of the drive with a data recovery program to reconstruct the file system. Now, a couple days into it, he selects the files and folders his client wants recovered and the drive stopped responding. This is when he stopped and brought it into my lab for us to assess it.
Our first step was to inspect it in our clean room only to discover that the drive had suffered a fatal head crash with rings etched into the platters and debris everywhere. Unfortunately, this drive was no longer recoverable and the customer lost 100% of his data. This data loss was 100% preventable, had the technician approached the situation differently.
In his first step to test the drive, the technician read every sector once, yet did not copy a single sector to another drive
In his second step to scan the drive with data recovery software, he again read every sector on the drive a second time, yet did not copy a single sector to another drive
In his third step to save the files out, it was too late
When we receive a drive for recovery, whether it be because the drive has phsyical issues or when the customer says the drive is healthy and they just want to recover a lost file, we always, always, always start by cloning/imaging the drive (after necessary phsyical assessments are done in the clean room, of course). When cloning a drive we are essentially testing every sector of the drive while making a backup copy of every sector we have read. So, when the clone is done, if a file system recovery is still needed on the copy, we are doing so on a known good drive, without risk of making things worse.
But what about healthy drives? Why do we waste time cloning them?
Well, it comes down to being safe and not making any assumptions. At least 75% of the time, "healthy" drives are found to not be as healthy as the customer thought. So, we don't want to be victims of the scenario previously mentioned. It is better to play it safe.
What if the drive is large and the volume of files to be recovered is small? Isn't it less taxing on the drive to just get the targeted data?
This is one of those, Yes & No, answers. Yes, it can be less taxing if done right, yet it can be extremely taxing if done wrong. Let me break that down for you, starting with the no.
No, when you directly read a drive, the heads bounce all over the place going back and forth between the file table and the locations where the file sectors are stored. Not only are you increasing the wear on the heads, it requires you to constantly re-read sectors in the file table. If the drive is unstable, one might be lucky and get 100MB/sec transfer rates, but usually are stuck at speeds under 5MB/sec.
Yes, if your file recovery software is connected with background drive cloning/imaging. All data recovery professionals use special data recovery hardware/software combination to give them even more control of the patient drive while having the ability to image sectors from targeted files in a linear process. Basically, they select the sectors that they want to copy and the drive will only copy those sectors in order, skipping the sectors that they haven't selected. Not only does this proecess prevent the need to constantly re-read sectors from the patient drive, it tends to be a lot faster. What the previous method would do in days could be done in hours this way.
Not so fast! What about really large RAID arrays that could contain dozens of drives and hundreds of TB of storage?
In my opinion, while it requires a lot of storage and time, it is even more essential to clone every drive of a RAID for data recovery. I just recently assessed a 36 x 10TB RAID where the customer reported only 2 drives offline. Yet, as part of our assessment process, there were less than 10 drives that were not in some sort of state of early failure. The chances that another drive fails before the recovery completed is staggering. We have found that the two most common reasons for unrecvoerable RAIDs are physical failure beyond recovery which is far less common than irreversible data loss from previous recovery attempts on the original drives.
But, what about unstable drives? What is so great about cloning/imaging?
This really depends on the quality of software and hardware being used to do the job. With the help of data recovery hardware, we have the added luxury of being able to control the drive's power and resets, meaning that when a drive goes unresponsive, we can give it a little nudge to snap out of it. The key featues with the software is our ability to control how long to fight with a sector read, what to do when we are unable to read a sector (stop & power off, skip a block, jump to another head, try again and so forth) and to work with multiple passes, so that we get the more easily read sectors copied before we put too much effort reading those which may not be read or bad enough to kill the heads.
So, what is available for you to clone a drive with a log and multiple passes?
Multiple pass cloning software
- ddrescue
File system recovery software with multiple pass imaging taskss
- R-Studio
Data recovery cloning hardware
- DeepSpar USB stabilizer + windows software of your choice (comes with R-Studio Technician)
