Time for a new external drive, or is this normal?

Hi everyone,

Is it normal for Time Machine partitions to crash and burn with some frequency, requiring first aid via Disk Utility, or is this a sign I've got a lemon of an external hard drive and need to buy a new one?

I've got a design-by-Porsche LaCie 500Gb external drive that I use for Time Machine. It's gotten bunged up twice in the last 4 months. When it's "failing," it tends to do things like not mount, spin forever, various error messages to system, etc. The first time, in October, I sent it back to LaCie, who claimed they couldn't find anything wrong with it, reformatted it, and returned it.

The second time was earlier this week. After about 4-5 repairs by Disk Utility over the course of probably 8 hours, with event store UUIDs not matching and deep traversals required, the thing seems to be back from the dead without any reformatting. Fingers crossed. But it was pretty touch and go there, with the Finder getting frozen up in early stages.

I don't find this too cool, but I'm not sure whether it's a hardware problem or just standard problems with Time Machine being finicky and ruining the file structure sometimes.

Do other folks have similar problems with Time Machine appearing to just frag their disks upon occasion? Or is it time to plunk down the pennies for a new drive? (And to try and let bygones be bygones with LaCie!)

so far you only seemed to have run into this issue twice in 4 months and were able to repair it once. that's not really enough to say what's going on one way or the other. TM IS quite buggy especially in leopard and such things may happen.
this is one of the reasons why it's a good idea to have a secondary backup solution using a different backup tool. as convenient as TM is it is still too unreliable to be trusted as the sole backup method. see this post by kappy for options

but it could be an issue with the drive too. if it happens too often I would reformat the drive. don't just erase it reformat it using the partition tab in disk utility. if it keeps happening after that i would replace the drive.
