Your drive is already at it's TRUE capacity.

There's a link on the EBAY site that claims virtually ALL 4+gb thumb
drives on ebay are fake. There are links to vendor sites that try to
tell you how to identify a fake drive. I've tried to buy two drives
locally off craigslist. Both were fake.

According to the legend, you have to reprogram the non-reprogrammable
code in the flash controller. This lies to the OS. The legend says the
devices
are manufactured this way and not merely reflashed by the scammer.

It would be nice to force the drive to report it's TRUE capacity so you
could at least use the thing. My searching has turned up no such procedure.

Problem solved - only Low Level Format restored this drive.
The original hack somehow changed low-level format, that Win Format
worked, but still showed incorrect value.
I tried to access it with Linux, but Linux couldn't mount it.

You can limit the user capacity of a regular IDE HD by writing to its
"Host Protected Area":

http://en.wikipedia.org/wiki/Host_Protected_Area

I wonder if flash drives support this feature.

Compact Flash might. USB probably not.

An IDE (pata/sata) flash drive could,
but USB drives would have to implement the SCSI mode page (unlikely).
