at my 450gb fat32 partition, a directory has a wrong content after improper usb drive disconnect; was:

/files (total 250gb)
/files/folder/
/files/folder2/
/files/somethn.gs

Now:

/files/weir?d?name, 5 mb

Windows and Linux are saying that most (400 of 450gb) disk space is occupied, but sum of all files/dirs is about 130gb, so it seems that files are still there?. No write attempts since discovery;

Rejected tools/methods:

• chkdsk(Windows7): checking completed, but no changes.
• fsck.vfat: attempted to ruin drive even more (there is a lot of LFN and unicode names).
• EasyRecovery. Didn't see the target folder (maybe wrong scan options? tried best match, but not raw scan - it would take days since the drive is usb 5200 rpm..).
