I've got an external firewire drive that up until recently has been working fine. The last couple days though it has been exhibiting odd behavior. I have it partionioned into two. One partition seems to always work fine. The other one never mounts now. I opened up disk utility and it lists the missing volume but says it is unmounted. I ran repair on it because it said "bad catalog" or something. No dice. So i formatted it and it worked fine for a day or so. Now its back to not mounting again.
In addition to this problem, i've noticed that sometimes when i plug in the drive it will power on the disk, power off, power on a couple times. Something is obviously not right. Any ideas?
PS: Formatted in HFS+ if that is helpfull.
