A little while ago, I booted my computer with my Memory Stick in its card reader. Since it had crashed, I had had to shut it off manually, and it scanned the hard disk and memory stick for disk errors. However, after this happened, the Memory Stick's capacity is now 23MB less than it used to be. Since I have a 256MB card, it used to be 250MB... now it is 227MB. I've tried reformatting the card on the PSP. Does anyone here have any idea how I can fix this?
