Bought 4GB Sony Memory Stick and having problems. Wondered if anyone else having the same problem? Basically, the memory stick only recognises 2GB of data. I've managed to dump 3 UMDs successfully using DAXDumper, but the memory stick will only keep 2. I formatted the MS in 2.71 and also 3.03 OE-A2 History - 1.52>2.71>1.5>3.03 OE-A2.
