Up until recently, Norton Utilities has always been able to reliably repair bad blocks on disks for me. However, with version 5.0.x, it seems to have lost that ability. It reports the bad blocks, says it fixes them (it takes forever) but they seemingly reappear.

I rarely have to fix bad blocks, and haven't done so since Norton 3.5... is this an issue with Norton 5 or could the drive's blocks (sectors, whatever) be physically damaged?

Are there any other utilities that can reapir bad blocks? To my knowledge, Norton is the only one.

Backup the disk(s) now and low-level format the drive(s). Reinstall your OS, applications and data.

Doesn't Tech Tool Pro block out bad blocks? I can't find my manual, so I'm not sure..

Also, this is pretty extreme, but one way to map out bad blocks is to do a low-level format using Drive Setup. Doesn't it map out bad blocks when you do that?

Caveat: If this is an IDE drive, then I think the low-level format is not available.

Anybody notice when the administrator asks a question how fast the moderators jump?

wlonh,

In case you've forgotten, you're an administrator now, too. Don's reply should include you as well

I'm going to be low-leveling the drive today, hopefully that wil do the trick.

Backing up a 40 GB drive that was pretty much full is a pain...

Well I've begun reformatting the drive... I forgot that you can't low-level an ATA drive, so I'm zeroing all the data instead.

Hopefully this will fix the problem; I don't really want to have to send the drive back.

Misha,

Good luck with your drive. Maybe you ought to contact Symantec with your question. btw, wow! A 40GB drive that's almost full?! My 10GB drive is only about 35% full (or is that 65% empty. Is your drive half full or half empty? And if you zero a drive in the forest, does it make a sound?)

and wlonh, I think you're in denial. Don't you know that you're "management" now?

Zeroing all data will do the same - Apple disabled the low level opiton because it's redundant.

It took about 8 hours but zeroing all the data has fixed the problem. Now it's time to restore all that data. Hopefully this won't happen too often, it's quite a drag!

migawd 8 hrs to zero the HD, jeez, imagine what a low-level format would've taken if you could've done it, what, double or triple the time?
