Like most of you, I fancy carrying a USB-memory-stick with me most of the time. One fine monday morning, I had to pick a few snaps from my PC and copy them over a friend's laptop. Simple, as it should be - it didn't work!!
I was not able to copy files from my machine to the drive! It would read like a breeze, but simply wouldn't copy! Tried the same on the laptop, and it works! After a few tries on google, I gave up to the fact(?) that it was a hardware issue.
A couple of hours later, I tried with some "smart"-er keywords which brought me to a long article on people complaining about USB issues. Somewhere down the line, this XP demi-god had quoted a solution.
Its to do with a registry setting, usually reset after XP-SP2:
is to be set to zero "0".
That was it! Simple and neat!
