I tried inserting a M2 card I was using in my old phone into the memory stick reader on my Windows XP PC (using a M2 to MemoryStick adapter). But the drive comes up as unformatted, and the formatter only offers to format it as 4GB FAT32.
It worked fine when I put it into my PSP and I was able to access the files that way, but the issue still annoys me so I'd appreciate to know why this is.
Is there an issue with using over 4GB MemoryStick on windows?
