Don't remove the memory stick

[HermXIV]

Just for future reference, DON'T remove the memory stick when the psp tells you not to. If you do all your data will be corrupt and it will be unreadable. I just lost like 4GB of porn, and 2 gb of games and a gb of music and pics.

Agreed. It is a bad idea. Sometimes it destroys your MS so bad it can't be formatted again.

And note: Zeus had 2x as much porn as games.
