Hi, I have two 8GB flash drives / memory sticks - let's call them A and B - which I've been using over the last few days. A has personal / home documents and is 60% full, B has a few work documents (about 5% full).

 

However (since today), when I insert drive A, the list of files that invariably comes up is (somehow) the list from B, although obviously if I try to open any of these 'B' files I just get an error message.

The 'A' files are still on the drive because when I do a 'Search' for named files they will appear and I can open them. However, I do not get a record of these (several hundred) documents when I stick in the flash drive. Instead it tells me what's on my other memory stick - Drive B.

 

I have tried inserting other memory sticks and the correct contents show up immediately - it is clearly a problem with memory stick A. Any thoughts / ideas? Many thanks in anticipation!

 

(Using Windows 8 btw)

Did you ever have the computer go to Hibernate while one of the flash drives was attached? Reboot the computer and try again.

Thanks, John, much appreciated  - yes, laptop actually ran out of battery and shut down while Drive B was inserted. I can well see that may have caused the problem.

 

Rebooting now  makes no difference. Memory Stick A and B both display identical list of contents although contents are clearly different. Haven't 'lost' any files or data from A, so is GDB (as suggested by hardforum thread) relevant?

Take both the sticks to another computer, copy all the contents off them into 2 folders. Format each stick, move the files you want back to whichever stick. Should do it.

No need for GBD. You are fortunate in that you can still access the files. I would do as bludshot suggested.

Thank-you, bludshot and John - I suspected the solution would be simple.

 

I have done the first stage - copied the contents of the one memory stick (the contents list of which has become hidden/overwritten) into a new folder in my D drive.

 

However, what I get (unsurprisingly, I guess) is an identical copy of the same problem ... correct files, wrong list of contents. Will copying them back onto a re-formatted USB (or a new one) solve this problem? Or just reproduce it? Apologies if I'm being dense.

I think if you copied them over you would be producing the same problem. If you do it, copy to a new flash drive. Is it possible to open each file and save them as a different name to another folder adding a suffix letter to the end of the filename. Does that solve the problem?

Thanks, John. A lot of the files are family photos etc - I have about 3,000! So opening / renaming would be laborious to say the least. If I know that there's a file called 'xmas2000g' for example I can locate it but of course I don't know what all my files are called.

 

The files are 'there' under their original name but 'under cover' so to speak - I am just seeking a reasonably fast way to recover the original list of contents which has been overwritten by the 'wrong'  list from my other flash drive: replace the wrong list with the correct list, so to speak. 

 

You'd think there would be an easy way. Thanks for giving it some thought, anyway!

I think the option at this point is to use software like GDB if it will let you scan the Flash drive and recover the files with their orginal names. I know Easeus Data Recovery will do this. It will let you recover 1GB for free in order for you to determine if it works i.e. recovers files with the filename intact. If it does, then you would need to pay and get a registration key to recover the rest. I believe somebody on the forum paid about $40 when they called Easeus for the key.

 

Another software solution that is similar is active@filerecovery which is a little cheaper. The Pro version is $35 with the promo code. But, it will only let you recover 64kb for free. It will let you scan and see if it can find your original file names.

 

GDB would be Getdataback Simple which works for NTFS and FAT. You can give that a try also. But, it costs $79

Sorted ... have discovered that by typing  'a', 'b' etc into 'Search' on the F drive I can call up a list of all the 'hidden' files beginning with that letter. Then copy and paste into a new folder on my local drive (then copy back onto memory stick if necessary). 26 operations (one for each letter) but better than thousands!

 

Thank-you however for technical advice ... as often happens just engaging in dialogue with someone else yields a solution. Luckily the (costly-ish) options that you have suggested will not be necessary in this instance but many many thanks for your expertise.

That was a nice solve. Thanks for the update.

 

Edit: I don't believe many people realize that having an external device attached during hibernation can cause big problems.

I believe there is a way to remove this problem, you go into the settings of the drive, and make it so it doesn't have caching turned on - or something like that - so that windows closes the connection to the drive every time its not in use.
