Ok, 4 hrs ago I had my computer off and my 1.50 PSP pluged into the the computer in USB mode. I turn on my computer and it says something like its checking the F:\ disk and called it a FAT file or something. So I then realized it was checking my PSP and then my computer read through all the documents of my PSP and the first thing that came up was something about replacing the bad clusters in one of my ROMs in my S9xtyl folder. Then it called it a null, and mentioned something about allocating.
It did this process for another one of my Roms, then one BMP file, then a folder in my saved game. It checked for memory space and then shut off before I could take anymore notes on this.
So once my computer came to, I check my PSP files and everything was there. I'm sure it did nothing wrong but I do want to know why my computer did this.
