Thanks mate, I will try.
BTW, why is this happening? It seems many people have this problem, and the guys who should give support (Microsoft) are nowhere near.... why there is problem under w7 and not elsewhere?
I tried testdisk on w7, but it doesn't offer me FAT32 partition... it detected RAW only
However now I am wandering - could this disk partition be "repaired" from XP, under which it works without visible problems?
EDIT
Correction: The USB drive is actually NTFS, not FAT32 as indicated earlier in the post.
On XP, testdisk detected Intel/PC partition.. at least it is not RAW.
Should I go with this?
EDIT2:
I joined cgs forum with that question.. will post here about the further developments :-)
