History of how I lost my files, anything more I can do?

#1 Post by timaneo » 25 Nov 2015, 08:08

I have a Seagate Barracuda 3TB ST3000DM001 that was completely full of videos and has had some major issues.

1) Half a year ago, about 500gb just vanished. The file names were still there but the files were 0kb

2) A few months ago, many of the videos became unplayable, they seemed to play just sound and it wasn't even from the video itself but from another source on the hard drive. Grabbing these files and transferring them over on a linux machine somehow fixed most of these.

3) A couple weeks ago, the hard drive said it needs to be reformatted to be accessed.

4) I have tried test disk to recover the partition. I had one 3TB partition but test disk saw a 700gb partition. Installing intel drivers fixed the issue and test disk now saw the complete 3TB. I ran a quick search as well as a deep search. There didn't seem to be any useful partitions that could be found. None of them had my files. (I had screenshots of all of my test disk findings but my computer had a forced update and restart and I lost the document...Not having a good computer month)

5) I ran PhotoRec and it recovered half my files, all of them in a folder with the file names missing. Having over 3600 unlabeled files is pretty useless.

6) After restarting windows, windows started doing a check/fix thing on the drive upon booting into Windows and it said "deleting orphan file record segment xxxx" Now my drive is active in windows and has a partition but shows to be empty.

I realize I did a lot wrong in terms of safely trying to recover the files. But now that I am here, is there anything else I can do?

Did chkdsk delete only 1 orphaned file or did you see a large list running deleting of orphaned files on your display?
Can you copy and paste the content of your testdisk logfile?
You'll find it within your testdisk folder.
Do you still have your partition available, after installing your Intel driver or did you create a new one?
Info will follow.

Hi Fiona,

It was a large list, thousands.
I tried to attach the log file but it didn't work. It is about 185 pages. Is there anything from it you'd like me to copy and paste or can I email it to you?
After I installed the Intel driver, Windows still was asking to reformat the disk but testdisk now saw the correct size of the disk.

Could you copy and paste the content of 3 pages of your log file?
At least, your disk gets recognized with full size.
So I'd be able to check your current partition structure (partition table) and could consider a boot sector diagnose and have a try to liust your files.
Otherwise datarecovery software would be recommended.

Which 3 out of 185 pages would you like to see?

I already tried PhotoRec as I mentioned in the first post, is there another software you recommend?

I'd need your current partition structure (partition table).
You can try to scan your disk with commercial datarecovery software too.
It's advisable to use a trial first and check the result, before you buy it!

Here is the last part of the log file, does this include what you need?
