With these drives, when they fail, I replace them. I am on my third one in
about 6 months. I think static electricity in my pockets or something else
is damaging them.

I have a USB thumb drive that my computers can read but can't write.

This device uses an OTI 6828 USB bridge chip and was distributed by
Pretec as the iDisk and also given out by Microsoft years ago (they
have nothing on it), but I can't find any information about it.

The OTI chip has a Flash Write Protect signal on pin 18
(http://www.costar.com.tw/pdf/OTi/Oti-6828.pdf). Have you verified
that it changes state according to the position of the read-only
switch?

Have you tried to format the drive? Is it possible that the directory
you are trying to write to has a read-only attribute???

Thank you, Frank. That's great in formation. I'll take a look at pin
18.

I had no luck formatting the drive, and nothing had the read-only
attribute enabled.
