Corrupt memory stick

[Accessless]

Ok I've had this USB Memory stick for ages and over the years it seems to have lost 2/3rds of its total capacity.

The original size of the thing was 1Gb but now you can't right over 333Mb to it (odd number (Used to be 666Mb) ). If I try I get the messsage: "Error copying file when accessing a new tape of a multivolume partition, the current block size is incorect."

Anway way is there anyway to recover this?

Here's some stuff about the Drive itself:

Drive Name:       G:\
Filesystem:       FAT32
Volume Label:       N/A
Serial Number:       6C2E-6.02
Total Sectors:       2031616
Bytes Per Cluster:    4096
Total Size 992.0Mb    (1040187392 bytes)

Device ID   USBSTOR\DISKVEN_BUFFALOPROD_CLIPDRIVEREV_1.00\A42005100400010510
Status      0x0180200a Started
Problem      0x00000000 (0)

Have you tried formatting it?

If you have, you may simply have worn it out.
After all you say you've had it for ages and flash memory have a finite amount of write operations it can perform before being worn out. Flash memory is divided into blocks and you may have worn some blocks out. Manufacturers typically promise 100.000+ write operations per block. Whether all blocks actually can do a 100.000 write operations is another story though.
The good news is that flash drives are pretty cheap nowadays so maybe it's just time to retire the old fella.

Didn't think I could repair it, actually it was retired last year. Just wondering if there was a point in keeping it.
