[SOLVED]Data Recovery help

Good day to all

As the topic says, need some help with a data recovery on my macbook pro retina with Arch Linux installed.

The data I desired to recover got deleted by mistake while I was as root, typing a rm -r command and was typing in the path of the directory I wanted to delete. Whilst typing, my pinky touched the Enter button when I going for the Shift to type the name of a directory, which so happened to be my user folder.

Upon recognizing the error, I Ctrl+C immediately within seconds, however my Documents, Pictures, Music etc folders got deleted along with other files cause, my desktop and terminal experience got greatly affected.

So today, I stayed home with the objective of recovering the data. Most of my important files got backed up to my cloud storage but one important one (ain't that always the case? x.x). I do audio recordings for my church but I work on them first and after converting them, I will upload them. Seven of them I didn't do in a timely manner so that's my main focus.

So far, after doing some online research as well as personal experience:

1. I have used photorec in my first attempt, got files but none of what I desired (or even recognize o.O )
2. I found out about extundelete but it says, it got 0 files to recover
3. I also found out about foremost, which didn't recovery anything meaningful to me
4. Lastly, I came here to the forum but before posting, searched through the forum for other things I could try. I learnt of ext4magic, which I just finished used. It did, "recover" files ( WAS EXTREMELY HAPPY ) but it seems to have just "recovered" files based on the current state of my hard drive. Has all my remaining files except the deleted ones.

So as a result, I am creating this post for further help and assistance. I will still do some personal research in the mean time but any info on this will be greatly helpful. Thanks smile

Re: [SOLVED]Data Recovery help

SSD? disable fstrim, make an image of the raw data first, otherwise with SSD/trim/discard, it's just gone.

How do I disable the fstrim?

Would disabling the fstrim improve my data recovery chances?

Re: [SOLVED]Data Recovery help

Were those attempts made from the drive the data was deleted from?  If so, unfortunately, all of those steps need to be performed NOT on the hard drive that has the data.  First step is the system needs to abruptly lose power, and not be cleanly shut down.  Second step is imaging the drive like frostschutz said.  Then, those programs then need to be installed and ran from a separate drive.  The deleted files (if not trimmed/discarded like frostschutz mentioned) remain on disk, but can be overwritten by new files (installed programs, web browser cache), which makes them irretrievable even from the best data recovery companies.

Re: [SOLVED]Data Recovery help

My understanding is if a device supports trim and a block has been trimmed then the device can return zero for the contents of that block or the contents of another block it remapped the address to for wear leveling.

No, I have a spare hard drive that has arch installed on it. I am using it externally to the macbook for all the performed data recovery procedures and which also I am on right now

I rebooted to then use the external

I haven't installed or done anything on the SSD apart from what I outlined above via the external

EDIT: https://www.youtube.com/watch?v=HN2T4CXLY6A

I found this video on ext4magic and decided to follow it on my data recovery attempt. When he does the first command with the block size and -J, it shows him all the pictures that was deleted. When I do it, it gives me nothing though it gives me an inode number for the folder I am searching for. When I perform the second command, it got nothing to recover

See if you have enabled it at all https://wiki.archlinux.org/index.php/So … iodic_TRIM or if a /var/lib/systemd/timers/stamp-fstrim.timer exists.

However that's just one of many ways to call fstrim, cron would also be an option. If in doubt:

chmod -x /usr/bin/fstrim
# or even
rm /usr/bin/fstrim

and worry about reinstalling it later... (util-linux package)

also check /proc/mounts that it's not mounted with 'discard' flag

Regarding the recovery, that's difficult to answer. You're looking for audio files? Which format? FLAC? WAV? MP3? ...

How was it recorded, where did these files come from, how large are they? Any chance still finding it on a SD card or similar of some recording equipment? Indirect data recovery is a thing too, sometimes.

1. I used systemctl to disable but will perform what you mentioned.
2. Format wav
3. All was recorded through my laptop

This is the output of it. What I am interested in is the Music folder (one dated 17th Feb). I may try out Docments and the others but my focus is on Music. But what do the 0s mean? I see a couple 4096 which I can assume refers to the block size based on what the guy mentioned in the video. Music is 1374 and most are 0

Re: [SOLVED]Data Recovery help

UPDATE: came across scalpel still with no good results. It found a bunch of wav files but 192kb small plus 300GB+ worth of other files which are of no use to me. Not sure what else to try sad

Re: [SOLVED]Data Recovery help

Hello there,

If you didn't mount the disk with discard flag, you shouldn't have to worry about fstrim/trim. It seems to me you getting close to recover some data. Did I miss recovery tools? I found testdisk very useful? On SSD, I had accidentally 'quick' format a partition. I was able to recover the partition and continue to use it as is.

Well the drive isn't in any way mounted, it has to be manually mounted.

As for testdisk, I am seeing recovery options as far as partitions versus a file recovery option. All partitions on the SSD are still intact.

The closest was ext4magic out of all I have used thus far.

Well in my mind, I thought it would just give me the same partition as it is in its current state. I will give it a go and report back.

It  also shows previous deleted partitions......so that's why I left it alone

EDIT: Ok I gave testdisk a go again after doing some more reading online. After selecting the SDD it prompts to ask the the partition tablet type where EFI was detected. Not much options there as far as what I saw online. If i choose Intel/PC partition, I have more options to work with. I managed to see the deleted files but as far as recovering them, example, the directories, they will be empty. So again I am at a halt >_<.

Quick question: As far as when I was install arch on the macbook, the guide I found use EFI. As I am now in the scenario I am, I was wondering if a non-EFI partition would have been better.

Thoughts?

Re: [SOLVED]Data Recovery help

Wanted to format with code but the colors don't appear. The red are the deleted files

The above is testdisk output after listing the files. The Directories are what I am interested in but if I try to list the contents, I get "No file found, filesystem maybe damaged." If I copy them (recover), the folders are empty

Hello there,

If you didn't mount the disk with discard flag, you shouldn't have to worry about fstrim/trim.

..otherwise with SSD/trim/discard, it's just gone.

I check online about the discard flag. It's present in my fstab for my /dev/sda3. Are you saying I should remove it?

Re: [SOLVED]Data Recovery help

Hi there,

It's irrelevant, the point earlier, prior to losing data, if that partition wasn't mounted with 'discard' flag, your more likely to recover data as oppose to the opposite. As far as 'testdisk', my experience is limited, perhaps you'll have better luck with other utilities.

Best regards.

Ok. It seems I have to just accept the fact that my data is gone, as frostschutz stated. All other utilities recover data but not what I am looking for or nothing at all.

--trim-sector-ranges
          For  Solid State Drives (SSDs).  EXCEPTIONALLY DANGEROUS. DO NOT
          USE THIS OPTION!!  Tells the drive firmware to discard  unneeded
          data  sectors,  destroying  any  data that may have been present
          within them.  This makes those sectors available  for  immediate
          use  by  the firmware's garbage collection mechanism, to improve
          scheduling for wear-leveling of the flash  media.   This  option
          expects  one  or  more  sector range pairs immediately after the
          option: an LBA starting address, a colon, and  a  sector  count,
          with no intervening spaces.  EXCEPTIONALLY DANGEROUS. DO NOT USE
          THIS OPTION!!

Read this online about the hdparm man page and it explains (at least to me) the 0s for all my deleted stuff versus a 4096. Everything got obliterated.

also check /proc/mounts that it's not mounted with 'discard' flag

Even my proc folder is empty.

Seems I have to "redo" my arch system cause a lot of stuff is gone. Thanks for the help and tips.

This isn't the first time I have lost data. Each time, it happens in a different way and I learn new things, whereby I put measures in place to prevent it. Just didn't do one folder due to its size as far as my online backup. Acquired a better understanding about hard drives thereby giving me a better insight of its config.

Best of all, I got more data recovery tools and learnt how to use them big_smile

My final questions however:
1. In my case where I saw the deleted folders but with a 0 size ( or block size), is it the TRIM that caused it? If so, how can I properly setup my SSD to prevent future data recovery issues?
2. I have a memory card as well, which did the same thing, doesn't output any of my deleted stuff. Never experience these issues with a HDD. So is this a flash media storage thing?
3. EFI/GPT vs MBR? Asking this since testdisk recognized my config as EFI/GPT which didn't have the options
of the Intel/Pc. Not looking to have this experience again.

Thanks

Plug in an external hard drive, copy your large audio or video files to it and then unmount the disk and store it safely. Online backups are overrated.

Well that's what I got to do for now. My system is messed up so I am going to reinstall after which I am going to setup periodic trimming and such like that I have learnt. What I might do is, after setting up everything, I will turn my second HDD to the back hdd, as you said. Might even directly record to the drive, not sure yet what I will do.

But thanks to all who has helped me. As I said, I learnt a lot through this. My system is going to be even better with the little bonuses i learnt big_smile. Take Care

Just remember that a hard drive (or SSD) that stays connected to a computer is a mirror, not a backup! You will definitely want removable or external media of some kind for backups. Computers are great devices for processing information, but not reliable storage of that data as you found out.
