How to clean a memory stick?

[BioHazardouz]

I was just going to do my monthly backup, but i put in my comp, it didnt work/psp.

To codex, i hardmod my psp, stp thinking im a nub, ive been hacking 4 years. ANYWAY. The psp is not the problem. Its the stick. Everything runs from stick, like emus, prxs, etc. I know the sticks the prob because i can put that mem stick in my unhacked, and it just constantly blinks. I can put my other hack mem stick in my hacked psp and it works. But it only has music and stuff.
