I have a MDD G4 1250 DP * I dual boot it into OS 9.2 and 10.5. SOME USB sticks 'show double' under 9.2, that is they appear to be separate disks/partitions and have to be copied to twice (to each 'disk'). I've tried re-formatting many times, in OS9, on a PC and on a Macbook Pro, in every case drives seem OK on other machines/other OSs .... but the fault persists when they return to OS 9. It only seems to be SOME sticks that this happens with, but I don't have enough sticks to establish a pattern as my larger sticks are NTFS and therefore useless in OS 9. I am flummoxed .. is this likely to be a software/hardware issue? Any thoughts?
