How to remove write protection from flash drive

While copying files from the hard drive to a 1GB "EP-Memory" USB flash stick, the message "can't continue to copy because the device is write-protected. Remove write protection to continue" OR something like that.
- There was plenty of room left on the memory stick
- Obviously, there is no switch (and if there had been one, no data could have been copied)
- I tried to format the drive, but it said "The operation did not complete because the media is write-protected "

Windows Explorer listed a number of folders and files (about 500 MB worth) that apparently were successfully copied, but if I try to access any of them, they are not available!

Is the stick trash?

I don't have any more 'flash drives' per se, but I do have three 2.5" USB HD that I use for backup; you know, the ones in the small aluminum cases that are USB-powered; two are 6GB, one is 40GB, all are different brands, and they all work perfectly.

The PC (HP XW4000) has its own built-in USB drives (1.0), and I added a 4-port USB 2.0 card - and they all work fine with the 2.5" HD. Obviously, the 2.0 ports are much faster, but they all work.

Does any of this make any difference?

Thanks
