Hardware :: Won't Show Up G-Tech G-Drive (500GB) External Hard Drive

when I went into the "get info" window for the G-Drive and switched the ownership/permissions dropdown from "read/write" to "no access". When I tried to switch it back to read/write, it would say read/write in the dropdown, but then I'd try to access the g-drive and I'd only get to the first set of folders--when I'd click on a folder, there would appear to be nothing in it. (Not sure if this is really related to my current problem.)
I then tried ejecting and remounting the drive, but it didn't show up on my desktop. Stupidly, I assumed my computer didn't recognize it at all and unplugged the firewire without ejecting thru disk utility. When I did this I got the device removal error.
I then plugged the firewire back in and tried repairing the disk in disk utility, but it said it didn't need repair. When I click on the G-Drive in disk utility the info at the bottom says:

Mount Point :/Volumes/G-DRIVECapacity :465.6 GB (499,973,603,328 Bytes)
Format :Mac OS ExtendedAvailable :
Owners Enabled :NoUsed :
Number of Folders :0Number of Files :0

0 Files! I'm worried about losing all my stuff! I then tried DiskWarrior (v4.0). When I first opened it I think the info at the bottom said "This disk is a Mac OS Extended disk. This disk does NOT appear on the desktop." I'm not quite sure about that "not" b/c after rebuilding the directory of the G-DRIVE I know it now says "This disk does appear on the desktop." Anyway, it's definitely not appearing on my desktop. After building the directory it said "All file and folder data was easily located. Comparison of the original and replacement directories indicate that there will be changes to the number, the contents and/or the attributes of the files and folders." And later: "19 files (and 2 folders) had a directory entry w/ an incorrect text encoding value that was repaired." And:

Disk Info:
Files: 51,646
Folders: 18, 493
Free Space: 65.42GB
(etc)

I then clicked "Replace" whereupon it said it was successfully replace. But still it did not appear on the desktop even after ejecting, remounting, rebooting computer, etc.

If anyone has any advice I'd really appreciate it. I'm pretty desperate here! Thanks!

(FYI I already tried going into the Finder permissions and unclicking and reclicking the box for showing disks on the desktop. Also, I plan on getting DataRescueII in case that's necessary, but i hope it isn't)
