Partition Magic & bad sectors (XP Pro)

Dale Walker

I'm trying to repartition a drive with on bad sector but Partition
Magic won't let me resize one of the NTFS partitions with an Error
#122 (bad sector) error.

Is there a way around this?

Let me say that I've had this 'bad' sector pretty much since I got the
drive and have been keeping an eye on the drive for over six months
now with no increase in problems so I don't think this will result in
a cascade of bad sectors later on (like what happens with older
drives). I feel the problem is a stable one so don't think it's worth
going through the rigmarole of replacing it just yet.

Yes, the drive is still under warranty but that doesn't really help as
I'll still have to buy another drive to copy all the data over to to
send the original one back.

Is there a way of persauding Partition Magic (8.0) to get around this
or is there another non-destructive Partition Manager that's clever
enough to work around the bad sector? Surely, if the program can
recognise it's there, it can work out how to avoid it.

If not, are there any utilities that can mark an NTFS bad sector as
good just long enough for Partition Magic to do it's thing? Yes, I'm
taking a gamble here but chances are I could recover from any
consequences from a backup if need be. I regularly defrag and at the
moment, the bad sector is sitting well away from any data and as I'm
trying to make the partition bigger, not smaller, I'm not going to
have any problems with trying to copy moved data over it.

Yes, use the hard drive manufacturer's ute to map the bad
sector away so nothing at the OS level can see it anymore.

That will normally wipe all data on the drive tho.

Yes, some drives will write a single bad on a power failure
during a write and its quite safe to map those away.

Are you silly enough to not have proper backups ?

Its stupid to attempt a repartition with PM without
a full backup of the drive, because sometimes it will
go flat on its face doing that, even with no bad sectors.

Doesnt mean they choose to bother tho.

Its more complicated than that with PM.

From a command prompt, chkdsk x: /r , where x is the required drive,
follow the onscreen instructions.

I'm afraid that won't work.

So far as I'm aware, chkdsk x: /r does not make sectors marked as bad
good again, especially if they're really bad (like mine). All it does
is 'attempt' to move good data away from any bad sector, and then mark
it as bad.

This is the scenario I'm trying to avoid.

Nope, Have a big pile of CDs full of backups. Trouble is, I never,
ever trust backups 100%. There's always something that goes wrong.
Besides, restoring from a backup of loads of incremental backups files
takes aeons. I have my data partiton mirrored offsite (synchronises
once a night) but haven't got enough spare space to do that with the
system partition so just do the odd incremental backup of that once a
week.

However, it's not that much more effort to reinstall an OS plus a few
apps if something goes horribly wrong. In all probability I would do a
clean reinstall rather than restore from a backup as it's the more
healthy thing to do.

Yep, but as already hinted in my first post, I do make regular
backups.
