I was curious if anyone else has had this issue:
I've got a 1 and 2 gig memory stick and they both experience this issue. I not that long ago downgraded to 1.5 and it is great except when I use a memory stick sometimes, most of the time now, it has issues keeping the data open. By data open I mean when I keep it on an icon that shows the memory stick when present, such as video or game, the memory stick icon comes up, goes away, comes up, randomly and sporatically after first entry usually. Almost as if I were taking the memory stick in and out. I think it may be a hardware problem but I was going to see if anyone else has had this issue before I opened it up. I'm curious if this is a firmware issue with such a high capacity memory stick or hardware issue with a PSP that really hasn't been used much. My brother didn't use his much before I downgraded it.
