Has anybody any idea what might of caused this?
In R studio correctly identifies the manufacturer and model with a 2gb fat32 partition.
Approximately 60% is used.

In Windows explorer the drive is incorrectly identified as 10gb with about 60% used and also shows 10gb in administative tools but the partition size under administative tools shows correctly as 2gb.

Device manager shows:
USBSTOR\DISK&VEN_UDISK&PROD_PDU10_2G_97I2.0&REV_0.00\0000000000003D&0

Access to files and folders is impossible using windows explorer but it is possible to scan and recover the files and folders but much data is missing. Other files and folders are repeated many times.

I don't think this is a chinese hacked drive!

Try to use Linux, to see if you can read it rigth.

i suggest to try the memory card recovery appz and see
most of them are fat not ntfs and see

or

Stellar recovery recommended in this case

Can we see the partition table and boot sector?

Extract the above archive to the one folder and execute the SIrun.bat file. The procedure will generate a report file named SIout.txt.

Hi fzabkar, Sorry for the delay in getting back.
I did manage to recover all the data.
I used R Studio but it was no good. Then tried Dmde and still no good.
Then I tried Get data back for fat and voila. All files and folders recovered with correct names and structures.

Here is the partition information from the secinspect tool:

Your memory stick is formatted as a superfloppy rather than as a hard drive, ie the first sector is a boot sector rather than an MBR. Maybe that's why R-Studio and DMDE had trouble with it ??? In any case, Sector Inspector assumed it was an MBR and analysed it accordingly (and therefore incorrectly).

That said, I would question whether your files are intact. The boot sector is clearly corrupted, and the type of corruption would suggest a hardware failure of some kind.

For example, the text string, "NO NAMU !", should be "NO NAME<space><space>". Similarly, "Removm disks" should be "Remove disks", and "Diûk0grsor" should be "Disk error", and "Press iny keù to0rewar|" should be "Press any key to restart".

These errors appear to be random, and they affect several bits.

I would suggest that, if you have any text files, open them in an editor and check them for errors.
