USB Issues: Exit code 21 kills mounts - how do you diskcheck flash?
I am a tech-newbie with two problems ongoing with my Mint 9 USB install on a 8gig flash drive. Iíve successfully installed it and used it twice on two machines, however after five or six times, two things have happened: One machine no longer sees it on its boot list at all no manner how many time I reboot it, and with the other the flash drive now only signals:
Unable to mount 60 GB Filesystem
Error mounting: mount exited with exit code 21: mount: according to mtab, /dev/sda1 is already mounted on /media/E8701CFA701CD0E4
I have scoured Google for remedies with exit code 21 and how it supposedly means the HD has pre-mounted somehow and such, and everyone has ultra-techie explanations that go over this newbieís head. I donít expect to get a spot on solution, but just a general way to go would be really helpful!
Also, Iíd like to learn to perform a FSCK and CHECKDISK on my flash drive, but Google entries say never do this without unmounting the drive first -- but donít explain how!
Any hints or recommendations would be most appreciated!

It seems you are trying to manually mount the device when the automounter has already mounted it for you in /media. Look in /media and see if there is a directory there. Next, if there is, see what device it is associated with with "df /media/dirname". Finally, you can "umount /media/dirname", and at that point you can run fsck on it. Example, if it is associated with /dev/sdb1, you can run "fsck -f /dev/sdb1". I assume that this is a FAT file system?Sometimes, real fast is almost as good as real time.
Just remember, Semper Gumbi - always be flexible!
