Hi,
this worked so far, but the flash stick didn't cooperate: It tells me
about being write protected. The switch on the housing tells No write
protection.
So I tried some of the other advices:
I downloaded the vendors utilities for the stick and tried: under XP the
utility didn't even recognize that the device is plugged.
Under Win98 it was detected, but there was the write protection
complaint too.
So, believing this the stick is actually write protected, despite the
position of the housing switch (maybe the switch is defective? But Acer
shouldn't have such problems after 1 week NOT using the switch)
Anyway: The one time the formatting via XP disk manager worked (first or
second try), it did show only 118 of 128 MB to be available,
additionally I could only store 6 MB on it, then the "drive full" dialog
box popped up. Since then the device is "dead".
Hmph!
