If it's not showing up in Disk Utility, even after rebooting, disconnecting and reconnecting the drive, etc, chances are good that it has died, or is at least mostly dead. You could try another utility, like [DiskWarrior|http://www.alsoft.com/DiskWarrior/index.html] or [TechTool Pro|http://www.micromat.com>, but there are no guarantees.
If I type diskutil list into Terminal I can see it, but I don't know what to do from there.
Use this command
mount /dev/(number of disk, without parenthesis)Press Return.
As Thomas states this sounds like a fried disk but you can run some other tests to be sure.
Here 2 other utilities you can use to verify...
DriveGenius, Demo In Demo mode you can run hardware tests but cannot repair. That's really all you need to let you know if the disk any good or not.
Let us know,
