Hey guys, i have an 80 gig EXT usb drive i use on the mac. Today while i was using it, the OS crashed, i was trying to delete a file that was in my user names trash can via the admins ID. once i deleted it it told me to press my power button to reboot my mac. i had never seen this i rebooted, everything is fine, except i can't mount my external drive. in the Systems disk util, it stats to show up, then it freezed, i unplug the drive, it then shows up as NOT MOUNTED. i tried to do a check disk, but it seems to not be working as its been on Verifying volume for a while now. Any ideas as to how i can fix this?
