I use a 256mb USB 2 memory stick on my desktop which used to work fine. I do not get a drive letter anymore in Windows xp Explorer (My Computer). The device is listed in the device manager as working. I can eject the device however I can't get a drive letter. In computer Management, Disk Management, it's listed as Disk1 with a red circle with a minus sign as 243MB Unallocated, but when I right click on it all it lists are "properties" and "help", no "assign drive letter". In properites, instead of a drive letter, it's just called "a" (with a small slash over the "a"!) Any ideas would be appreciated.
