I tried using another USB flash drive, and that worked. Put the old one back in, and it still didn't work, so I reformatted the flash drive. After that, it works as it should!
My guess is that the flash drive got corrupted when a faculty member, not knowing to use the FTP, just swapped flash drives, and mine (the original) got corrupted in the process. That's the first time I've seen a corruption that would allow the drive to be used in a computer port on one computer but not be used on another. Thanks for the suggestion; I'm very relieved it worked!
With that in mind, is there a suggested safe way to eject a flash drive on the Ross other than a powerdown before removal?
