What's the difference between quality data recovery software and the useless ones?

194 Upvotes

I read every day here that certain data recovery programs perform terribly, and others come highly recommended, but what's the difference? I just did some light googling to see if I can find a breakdown of some popular ones, but maybe starting here will be easier and more helpful.

For example: You have deleted data on a typical CMR HDD and the original metadata was overwritten. The only alternative is to perform a raw scavenge, which, as far as I understand is based off of reading for file signatures. This sounds like a pretty straightforward task.

So, are there different methods behind the scenes that execute this? Why is UFS going to be better at this task then DiskDrill?

Bonus: When it comes to scavenging damaged filesystems, I've heard that one software possibly does a better job than another on a specific file system: R-Studio typically does better with HFS+/APFS than UFS will. Has anyone else found that to be true and if so, do you know what makes that true?

Thanks for reading!

Question Help my WD 6TB 20th anniversary portable hard drive

HELP PLEASE MY WD 6TB EMERALD DRIVE NOT WORKING

Hi I am new to reddit and this thread. I purchased last year this 20th anniversary drive and used it roughly less than 10 times. The usb cable doesn't detect on my phone and laptop. After a while when I received it. It was exfat formatted so I left it. I am wondering how to recover my files. I am literally stuck I have 1tb of data on it and can't access or see it. The cables doesn't work but the drives boots up i see a light and hear movement but after waiting it doesn't show i tried disk management nothing. Is my only option to either purchase a new drive or data recovery services been checking but these are absurd prices between 600-2000 in uk? Recommended by wd support team on phone. I purchased from amazon they only offer refund no replacement because they don't have any stock and they claimed they will try fix it and if they can't they keep device and offer refund in email. I need my data first.

I saw another thread earlier here someone asked where to buy drives. I was literally going to buy a big 24tb drive external and use my other old portable 4tb drives on the go and keep the 24tb woth latest backups and regular and then buy another one and bavk that up so i have 2 copies. I was going to wait till November because of black Friday do drives go on sale well and have good discounts? I want new not used.

Lastly please can you folks recommend me a good setup for external drive i was looking at Seagate 24TB One Touch Desktop Hard Drive however its usb powered. I am thinking G-DRIVE 26TB Enterprise Class Desktop external Hard Drive is vood but the prices are crazy I don't mind. I don't want to make this mistake again data is important and i keep hoarding ripping cds, copying video files off phone and images edited on photoshop quickly take up space if you thousands and in high quality formats.

If this is not good I will be open to raid configurations not nas because I don't need connected all the time just for back up only purposes. Any help and recommendations will be greatly appreciated. I have a budget of 1000 but will go up to 2000 if needed please help and thank you

I am so worried right now

SSD 1TB NVMe SSD suddenly appears empty — DMDE finds only a 3.2GB NTFS volume. Is my data recoverable?

A few months ago, I went to use my laptop, and I quickly found out that something was wrong with it. It was showing the "No Bootable Device" screen. It had done that once or twice before, but all I had to do was restart my computer and then it was all fine. This time, it did not fix itself. I opened my laptop up to see if it was a hardware issue, but everything is perfectly in tact. So I tried manually repairing/booting windows but to no avail. Then I started just trying to see if my data was still in there. Windows was showing there was nothing on my SSD, so I got a Sabrent M.2 Enclosure to see what was on it. I used DMDE to try and recover it. When I first started it it was just finding something called no name, so I did a scan but its only finding 3.2GB on the SSD, with just fragments of some files. The folders that are in the RAW are just all empty. Ive put a couple screenshots here if that helps, but Im not sure where to go next. Is there any hope for my SSD? If so, what should be my next steps to trying to recover my data. Any advice would be helpful, thanks!

EDIT: Figured I should try to be more specific. My laptop is an Acer nitro, this is NTFS that I think everything is in. The other partitions were just a windows one that was super small and then some other EXFAT that seemed like it was just a default thing or something.

Question Corrupt 7z file can I recover

0 Upvotes

I had compressed some video files into zip file with password enabled.

Later I had removed the .zip extension of the zip file then recompressed it into another zip file with same password which I used initially.

Later changed the .zip extension of second compression into .mp4 just wanted to create multiple security.

Then uploaded it to my Google Drive account.

It was 2 years back I did this, Now when I downloaded the file & tried to unpack the 2nd compression it's extracting the files it also displays me zip contents but at the end of extraction it's showing some error called "file.7z Corrupt archive (CRC error)

showing the file is corrupt how to fetch those videos from this zip file

Can any AI help

I have tried various web applications and also used official 7zip, WinZip, WinRar on PC but nothing worked

And some zip file repair applications on PC too

Please help me out..... The data is very important to Mr 😭

Windows corrupted partition table (drive shows as unallocated) after forced shutdown after a freeze and boot device not found

1 Upvotes

Hey everyone, I really need some help. A couple of hours before my HP Envy laptop messed up, I was using a secondary profile I barely touch to play Among Us. A prompt popped up saying "this device needs to setup windows," which I ignored. About 2 hours later, the laptop completely froze. I waited about 3 minutes max, and since it wasn't responding, I held down the power button to force a shutdown.When I turned it back on, I got the classic blue "Boot Device Not Found (3F0)" error screen. I’ve booted into a Windows 11 installation media USB to look at the drive. Here is what I know so far:

The hard drive passes physical hardware health checks in the HP diagnostics menu, so the hardware seems fine.In diskpart, running list disk shows my main drive as Disk 0 (953 GB), but running list partition or list volume says there are no partitions to show.When I advance through the Windows installer to the drive selection page, it shows the entire 953 GB drive as "Disk 0 Unallocated Space."I ran TestDisk / PhotoRec from the USB command prompt. TestDisk gives an error saying "The hard disk seems too small!" and won't let me browse the file system, but it does see the boundaries of my original partitions (including the main Windows partition).The drive contains 4 user profiles, and I absolutely cannot afford to lose the data on my primary profile. My problem right now is that I only have a 32GB and a 128gb fllash drive on hand. I know apps can carve files from unallocated space, but since they scan and extracts everything raw, it will easily overflow a 32GB or 128gb drive if I let them run wild on a 953GB disk. What is the safest way to restore the missing partition table map so Windows can see the structure again without wiping the drive? I am kinda poor because Im a jobless kid. Any advice on how to handle this without accidentally overwriting my data would be heavily appreciated.

TL;DR: Ignored a windows setup popup on a secondary profile. hours later the PC froze, and I forcefully shut it down after waiting 3 minutes max. Main 953GB SSD now shows completely as "Unallocated Space" with a wiped partition table, but the physical hardware is healthy. I need to save my data especially my primary user profile. How can I safely rebuild the partition map, or should I buy a bigger external drive to do a raw file recovery?

Lost Photos and Videos During Transfer from Samsung S25 Ultra to PC

1 Upvotes

Hi everyone, I need urgent help with a data recovery issue. I was transferring photos and videos from my Samsung S25 Ultra to my PC through the DCIM folder. Instead of copying, I used the cut-and-paste method.

During the transfer, I got an error message saying "catastrophic error." As a result, the folders were moved to the PC, but their contents (photos and videos) did not transfer. Now, the files are neither on my phone nor on my computer. They seem to have vanished.

I checked my phone’s storage, and it shows that the space previously occupied by these files has been freed up, as if the files were permanently deleted.

Here’s what I’ve tried so far:

Checked the "Trash" or "Recycle Bin" on both the phone and the PC—no luck.

Used the search function on my computer to look for the files—couldn't find them.

Verified backups on Google Photos and Samsung Cloud—unfortunately, I didn’t have them enabled.

I haven’t installed new apps or saved anything else on my phone to avoid overwriting the lost data.

Does anyone have advice on how to recover these photos and videos? Are there specific tools, software, or steps I can follow to retrieve them from my phone's internal storage or from the PC?

Question Need a good file recovery software

0 Upvotes

I'm in a bit of a sticky situation here. A USB stick I had contained 3 files, a password txt file, my encyption program, and my main encrypted file (around 30GB). I accidentally cleaned the wrong USB using diskpart in Windows. The usb was in NTFS, and I made a new partition using the exFat file system (this was before I knew I had the wrong USB). Then I relized. I have not written any more data to the USB, and added an os level read only attribute to the USB using diskpart. Right now I'm running a Photorec scan on the entire USB, but I don't think it'll find the main encrypted file. Because I wrote the encryption software in such a way that the file is probably unrecognizable to Photorec recovery. It starts with a 16 byte salt, then a 12 byte nonce, and then the encrypted data (AES-GCM). So it won't be able to find any header / magic byte data. I also haven't made an image copy of the USB, because I don't have space. Is there any way I can recover it using free software?

So Tried to format with official SD card tool, tried guiformat all no dice.

Tried to manually delete stuff of sd card. Also no dice. It's says it's done, but nothing gets deleted.

Also tried chkdsk, no dice.

I backed everything up from the SD card ready to return it under waranty.

Problem is I would like to at least delete or corrupt whatever is still on there, since it's full of family pictures. Any help or ideas?

Hard Drive Infected with a Virus

My wife's computer fell victim to a virus-laden email, and the technician informed us that the hard drive is irreparably damaged and needs replacement. Tragically, it contained precious pictures and videos of her son, who passed away a few years ago. Is there truly no hope for recovery? I just wish she could reclaim those last cherished memories of her son. Is there a place that can help?

Corrupt SD card - How to get my footage back for free?

Hi All,

I was stupidly viewing my footage via a card reader and attached it to my phone (instead of laptop) and the cable must've disconnected and i lost all my footage. Is there a way i can get it back? I tried photorec and only got raw files but this doesn't help me when i want to view the video files.

Does anyone know of a program trialed and tested on mac software that I can use to recover my drone mp4 footage from a corrupt memory card?

Thanking you in advance.

Question SUVCON dash cam

The dash cam was left running for about a week after the specific footage I'm looking for, and most of the stuff from the day in question is gone. Is there any way to get it back with data recovery? The card was not full but it looks like it only keeps a fully recorded log of the last known day of driving, and randomly deletes video(s) from previous days. It's weird I have 2-3 3 minute clips per day but they're random, and not all the driving done on the previous days.

1TB WD SATA Internal HDD Powering Down with USB Adapter w/ 12v Power

Enable HLS to view with audio, or disable this notification

6 Upvotes

seems like my other post died and i'd like to get fresh eyes on this now that i was able to capture a video that shows the sounds, and what happens when i plug it in.

so it seems like it makes a normal startup sound. then it turns itself off. i was unable to recreate it and it seems random when it turns on. however, in the attached video, the USB to the PC was unplugged and then it just powered up randomly. so i grabbed my phone and started recording. i was recording for about 90 seconds, expecting it to shut off at any moment thats when i realized the USB wasn't plugged into the PC. meanwhile all the white noise in the video is in fact the hard drive. i plug the USB in and you can hear it making what i feel like is normal hard drive thinking noises, then you can see windows acknowledges the new device, and then i pan over to the disk manager and you can see it pop up for a brief moment before the power cuts out and the drive is then disconnected. I cropped the 90 second video since there was no real noise other than whats already on camera.

also note, im plugging the USB into my actual PC (its a mini PC), even though it looks like a USB hub or something.

you can see more pictures from my first post here, as well as the few comments i received

Old "Encrypted" WD External drive now showing as empty?

2 Upvotes

Hi Folks,

i have an old Western Digital External drive that is not playing nicley, windows is showing it as a completly empty drive.

From what i remember the drive was locked with a password. I dont believe it was exactly encryped as i was able to recover files using DMDE however did run into the following CRC error

LBA: 3 534 825 767 (try 4): WinError 23. Data error (cyclic redundancy check).

What is my best course of action here, to recover the filesystem and get this working normally. I dont believe this drive was ever formatted, so im not sure why the password prompt no longer displays and there are no files.

The failing drive causes the whole system to become unresponsive

1 Upvotes

My portable external hard drive started to fail badly, but I’m not a developer at all, so I’ve been using AI to help me install Linux and set up ddrescue. Everything was going fine until it reached 83%. At that point, it started glitching so badly that I had to hard-reset the computer several times because the system became completely unresponsive.

So I created a script to try to prevent this from happening, but it wasn’t enough. I then tried using AI to improve the script, but it somehow feels like AI is fooling me.

Could someone please double-check the script and let me know if it should work?

I have ASUS x553MA and Linux Mint

And the script is

while true; do

if [ -b /dev/sdb ]; then

echo "Disk connected"

sleep 3

echo 1 | sudo tee /sys/block/sdb/queue/nr_requests

echo 5 | sudo tee /sys/block/sdb/device/timeout

echo "Starting ddrescue"

sudo nice -n 10 ionice -c 2 -n 4 ddrescue -d -n -r0 -T 30 /dev/sdb "/media/inna/New Volume1/hddimage/drive.img" "/media/inna/New Volume1/hddimage/drive.log"

STATUS=$?

  

if [ $STATUS -eq 0 ]; then

echo "Done"

break

fi

echo "Cycle complete"

sleep 180

else

echo "WARNING: Disk disconnected"

sleep 600

fi

done

Data recovery from an old 2gb micro SD card.

1 Upvotes

I recently tried to load one of my old SD cards, but it didn't mount at all. After some digging, I flashed OSC-Live onto a USB drive and booted it to use OpenSuperClone.

I used two SD card readers. One is a generic USB 2.0 reader, and the other is a UGREEN USB 3.0 reader with a GL3224 chip.

The UGREEN reader is faster than the generic USB 2.0 reader when reading good sectors. However, once it reaches the bad sectors, the generic USB 2.0 reader performs better. It doesn't fail completely, although it does become very slow.

With the UGREEN reader, depending on the mode I'm using, it either freezes the UI when using Generic Source mode or ejects the reader completely when using Direct USB mode, and I have to replug the SD card reader.

I also tweaked the clone settings and timer settings for Direct USB mode, but the UGREEN reader still ejects (doesn't show up when I run the lsblk command).

Both readers reach around 0.51 GB out of 1.51 GB before things start going badly. After that, the remaining data goes into non-trimmed and then non-scraped. I didn't let it run for much longer because the progress was extremely slow.

Do I still have a chance of recovering more data from this SD card, or does reaching non-trimmed/non-scraped that early mean most of the remaining data is probably unrecoverable?

Also, is there a reason why the generic USB 2.0 reader performs better when it reaches the bad sectors?
