Flash files restored but with generic names. Partition not found.

Hi everyone,

my 128 gig flash drive became unreadable. Probably, I suspect, as a result of me persistently using it on both PC and Mac. I followed Jumanji's breakdowns of TestDisk and Partition Wizard from Nov 2012 and both products recovered files. TestDisk found 964 files and I recovered 942 before I got tired of waiting for the estimated 3 more hours. The files are fine but have generic names and no directory structure. After reaching the Quick Search point my experience diverged from Jumanji's example in that TD couldn't find a partition.




I could recover files though:




but this is how they're defined:




This is, of course, miles better than nothing but many of the files are used by editing projects which now can't locate them. I couldn't work out if TD could restore any more information so I tried the demo version of PW Minitool Power Data Recovery. I let this run it's full course and it found only 430 files. I can only restore 1gb of these and a couple of test files shows that they are still generically named without directories. I haven't bothered to complete this as TD has very probably already done it for me.



Is there any way I can restore the original filesystem and filenames?

Thanks in advance

Your problem seems need a recovery expert. Best solution is to try a specialist to fix this problem. Flash drive is very sensitive external hard drive.

The structure isn't worth the somewhat surprising cost of employing a recovery company. Also, the last time I did that I couldn't believe the amount of snide business practice I encountered at the prominent end of the UK data recovery profession.

Hello Jumanji and thanks for getting back to me.

So, I ran the flash drive through GetDataBack Simple and a Level 1 scan quickly shows an Exfat system. It's the only filesystem listed and, when selected, it lists the directories and contents correctly but the contents are all from my Mac.




There's a lot of data missing which was loaded from my PC. I tried running Level 2 but it only listed a smaller selection of the Exfat stuff which appeared from the previous scan. I've just completed Level 3 which took a lot longer and it also listed some Lost & Found folders which included some video. No audio files have yet been listed. There are many on the drive and TestDisk found them.



I'm going to run Level 4 and go to bed as it's going to take quite a while to complete. I'll post results tomorrow. G'night!

OK. I do not have any rub with MAC. But still consider it as a data recovery problem and check on it.

1.) How was the 128GB formatted? On Windows or Mac? What file system?

2.) Getdata back read it as Ext3 and showed you quite a number of folders. Do any of these files in that folders are in the data recovered by PhotoRec? My intent is if files are common, then you may be able to rebuild the folder structure and assign the right file names with the help of folders and files shown by Getdataback. So explore that possibility - though it is a manual work.

3.) We will in any case go with TesttDisk and check what it shows.But that after my return from the two-day outstation trip.

4.) During my two days absence you may do the following:

a) Post a screenshot of Windows Disk Management with only the 128GB flash drive plugged in.( Unplug all other external/flash drives)

b) Post a screenshot of it in Minitools Partition Wizard Free Edition (30.49MB) Free download Magic Partition Manager Software, partition magic alternative, free partition magic, partition magic Windows 7 and server partition software - Partition Wizard Online - the very first screen that appears when you launch it.Then run Partition Recovery Wizard in it, Quick Scan and post a screenshot of the Partitions found Window. After taking the screenshot cancel and close PW ( Do not Apply and write anything to the flash drive)

c). Download GetDataback for NTFS, run it and check whether it shows any folders and files. ( Read the documentation/ help file on how to use that program. I had never run it.:).) Data Recovery Software Products and Downloads - Runtime Software Products Check whether it is any different from the Ext3 partition shown by Getdataback Simple

In all these things we are only scanning the drive taking care not to write anything on the Flash drive.So no harm to the data.

Ok. Good Morning!

Now, Jumanji, I'll point out here that, at this point, I have everything I need to manually rebuild the directory structure from the GetBackData images and the TestDisk recovered files. If you're as busy as I think you are please feel free to apply your considerable knowledge to other projects and Thanks Very Much for the help thus far. If you'd like to do it just for the sport I'll happily be a lab monkey.

I'll outline the results of the last scan for informative purposes anyway.

The Level 4 scan produced pretty much the same list as the others but included a folder called 'New Folder' which contained jpg files. This was the only new found data. I know there are 100 -150 audio files stored as mp3, mp4 and flac which TestDisc has recovered. They have obscure filenames but they play and the id3tags are intact. GetBackData doesn't list these. One other weird thing is that TestDisk recovered a high number of obscurely named DVmovie files which are actually tiny (approx 1 second) chunks of longer video files. I'm guessing that they may be dissembowelled mpegs. I have back ups so it's not a critical issue. Here's a pic of the last scan anyway:

Aha! I think we were typing replies at the same time. Thanks Jumanji, I'll run through your instructions and let you know what happens.

Inbetween I peeped in into Seven Forums and saw you online and decided to make that post.:)

Sticking to our travel plan. My next log-in from this PC on Saturday the 18th.

Hi Jumanji,
images of the 3 procedures are included below. The disk Management and Partition Wizard look equal enough and MiniTool NTFS didn't find any NTFS data. In response to an earlier question of yours I would have formatted this as ExFat because I thought it would manage both PC and Mac data sufficiently well. I probably formatted it on the Mac. Both systems now ask me to format the drive when I connect it.
