can't unmount or format USB drive

**yer916** · October 5th, 2012

so I used startup disk creator which screwed up my USB drive and now I can't unmount it or format it.

here's what I get when I type blkid:

Code:

/dev/sda1: SEC_TYPE="msdos" LABEL="DellUtility" UUID="07D9-0619" TYPE="vfat" 
/dev/sda2: UUID="06C8DF6BC8DF578F" TYPE="ntfs"

<_Pac__ type vfat (rw,nosuid,nodev,uhelper=udisks,uid=1000,gid=1000,shortname=mixed,dmask=0077,utf8=1,showexec,flush)

it seems as though the drive is mounted with a name that has 2 lines... which makes everything I tried impossible.

trying to unmount with Disk Utility gives me this error: "Error unmounting: umount exited with exit code 1: umount: /media/ure>: not found"

please help :[

Ok, so I was finally able to format the thumb drive, but now there are FIVE permanent "ure></Pac" drives appearing as mounted drives, even when the thumbdrive isnt plugged in.

they are named
ure>
<_Pac

ure>
<_Pac_

ure>
<_Pac__

etc...
blah, please help
