External Hard Drive acting funny
My external hard drive has been acting strangely. It's a 250 GB LaCie. I use it to back stuff up, or to render movies on (Scratch Disk). I haven't used it for a couple weeks (vacation!), so it's been empty for a little while. However, when I began to add stuff last week, it began stalling my computer (beach ball). I erased the whole thing using Disk Utility after a failed Repair Disk, and ran a Repair Disk again. It told me no repairs were necessary. I've just begun to add stuff to it again. It's stalling again. When I use Disk Utility, I get the following:
Verify and Repair disk “Backup”
Checking HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Invalid sibling link
Volume check failed.
Error: The underlying task reported failure on exit
1 HFS volume checked
1 volume could not be repaired because of an error
Is my disk dying? Can Disk Utility help me anymore, or should I buy DiskWarrior or TechTools? I note that there is nothing of importance on the disk (I have a duplicate on the drive in my computer).
Thank you in advance.
