A USB 2.0 (says its v.1 compatible) non-branded flash disk is not appearing on a rev. A clamshell iBook runnning 10.3.1. It doesn't appear in the disk uility list of connected drives (not just without a volume- it doesn't appear at all). It works fine on XP with USB 1. I have read everything I can find on USB flash drives, and I am going to try reformatting it on the PC, in case it has some form of passwording or some wierd format done at the manufacturers. Anyone had similar experiences/heard of any solutions? Thanks.
