I just got a new SanDisk Cruzer Mirco 1GB flash drive to uses for my new G5 Powermac. When I first plugged it into the USB port I got an error message saying "Disk Insertion The disk you inserted was not readable by this computer" with the options to "ignore" or "eject". I'm new to Macs but knew I had to probably reformat the drive, which I did in Disk Utility to Mac Extended (journaled and also tried it not journaled). But I continue to get the same error message everytime I connect the drive to my computer. I can see the drive, open it and save to it but it's bugging me why i'm still getting that error message. Am I missing something here?
