I have a Sony Memory Stick Duo Pro. I have transfered a 200MB file to the stick over the PSP at a speed about 120KB/s. during the transfer I press the home button to see if there is enough battery left but this also broke the transfer. Then I tried to transfer it again, but now I only get a speed of about 70KB/s.
I also tried to reboot computer and PSP but its still at 70KB/s
Does anybody know what can be wrong?
