I have a hard drive that will no longer mount. I've tried changing the cables, repairing disk utilities and trying it on another computer, repairing disk permissions, and when I go through disk utility it sees it as an unknown device. I also tried updating external with the LaCie update tool. So at this point I've resigned myself to using either DiskWarrior or DataRescue 3 to try and retrieve the files. However, when I hook my macbook up to the external and then run either program it does not seem to be able to locate the external hard drive. Am I missing something, am I supposed to be able to see the external separately? Is it just bricked and all hope is lost? Any insight would be helpful.
