Good day! Thanks for the responses, folks.
bthylafh : No, it's not there..
notfred : Thanks, I tried the suggestion in your link. Automount is enabled. But still no go.
bryanl : Sorry, it doesn't appear there.
sironomus : Yup, that's also what notfred suggested. The boxes are checked. No go..
justbrewit : Fresh install. Reformatted hard disk from Windows XP.
Update : I reinstalled Ubuntu 10.10 again, and this time the USB drive is mounted. Thing is, when I 'safely remove' the drive, i always end up doing it twice because Ubuntu will not dismount the drive the first time I do it. Fed up, I just went back to Ubuntu 10.04. It works well enough anyway. No time to look for solutions. It's just sad that Ubuntu always has lots of bugs.
Thanks for all your help, fellas. Have a good holy week.
