Hello....

I had a USB memory stick plugged into my Win XP (pro) computer.

The machine then updated itself with the many various MS patches going
back a number of weeks. This it successfully did.

After a reboot, I found that the USB device was no longer available
(or the files on it) as xp reported it as requiring a format.

Why would this happen, and do you think its possible to retrieve the
data on the stick?

Thanks.

What if you unplug and re-plug in the USB?

I don't think it should write anything to the stick in the operation
you describe. Maybe an issue with the USB driver/port? Have you tried
the stick in a different computer?

Different machines running xp all come up with the same response
"the disk is not formatted..... etc"

This can arise if there was a delayed write failed message,
which can corrupt the drive.
Did the suggested unplug/replug work?
Google for delayed write fail, see if anything matches your
problem.
To prevent it I use a little utility called USB Safely Remove.
Think it ckecks if the drive is free and that everything has
been written.
If you are still stuck you could try some of the file
recovery utilities, but if it is the file table that is
corrupt you may have a problem.
