I have a 2GB USB drive that was formated on a Mac. I now want to reformat on 64 bit Vista. The drive does NOT appear when I open up the computer. The drive does appear in Disk Management without a letter. When I try to assign a letter to the drive I get a pop-up that says "The operation failed to complete because the console view is not up-to-date. Refresh the view by using the refresh task. If the problem persists close the Disk Management console, then restart DIsk Management or restart the computer." I've rebooted to no avail. I've tried diskpart.exe. When I list the disks or volumes the USB drive shows up but when I try to format it I get the message "Diskpart has encountered an error: The system cannot find the file specified. See the System Event Log for more information." There is no more information in the event log. This is a cheap 2GB drive and it probably would be quicker to go out and buy a new drive but I'm curious. How do get Vista to recognize this drive?
