I need some help please. Both me and my girlfriend have Macbooks (c2d) and we're both running Mac OS X Tiger and we've been having problems reading a few usb flash drives. It all started when my girl tried to load her usb flash drive the other day, and it would mount on the desktop, neither on her Macbook nor mine, we used to be able to mount it before so, this is new. She then went to uni and tried opening it on a PC and it worked. Then later today, a friend of hers came by the work on some uni work, and same thing happened, we tried to load her friend's usb flash drive, and it didn't mount (on both macbooks). Our usb ports are working because we can charge the ipod and use external mice and stuff. For the record, on both usb flash drives (my girlfriend's and her friend) have Windows files on them, along with mac os x files too. any ideas? I tried repairing permissions but it didn't work.
