Hi,

I have a maxtor 120GB drive which developed bad sectores on all partitions.
the drive has 3 partitions.
I deleted 2 of the partitions and reformatted using partitionmagic and got
rid of the bad sectors in these partitions.

The third partition is the system and is quit large so I dont want to copy
it and reformat.
Is there a way to remove the bad sectors form the ntfs list and recover the
space without a format?

I heard that dfsee utitily can doe this but I cannot find specific
insturctions of an ntfs partition.

Thanks
Hod

How many bad sectors in total ?
the drive has 3 partitions.

That means you are running without backups. Mad.

No point really, only one file per bad sector is affected.

If you have deleted that file, one of the security wipes
that wipe free space should get rid of the bad sector.

First find out why you're getting bad sectors. IDE drives map out bad
sectors at the first opportunity, so not seeing them on the disk doesn't
mean that the disk is in good shape. Once an IDE drive starts showing
multiple bad sectors it's generally going to die real soon.

Beware. The bad sectors shouldn't be there. Assume the drive will soon
die.
 
Hi Ron,

Got 9 bad sectors.

I tried chkdsk several times and it does not get rid of the bad sectors, is
that the security wipe you refer to.

I want to get rid of the bad sectors to do a partition copy with
partitionmagic and not retain the bad sectors.

Hi Ron,

If this is the case why does Maxtor support tell me to get reed of the bad
sectors by doing a low level format and not tell me to return it?

Your HD is about to die. Replace it.

You cant get rid of a bad sectors. You can only use utility to mark them
bad so no data tries to write to it.

He said he has already with the partitions he didnt mind reformatting.

The reformat likely triggered the drive into reallocating the bads.

Its more complicated than that.

Urk, looks like the drive is dying.

See what the Everest SMART display shows for that drive.

Nope. A security wipe writes crap into unused sectors, so no
one can snoop there. That should trigger the drive's automatic
bad sector reallocation if the bad is in an unused sector.

That sounds like the remaining bad sectors are in files.
You're going to lose the data in those bad sectors.

Deleting the files with bad sectors in them and using
a security wipe should get rid of the bad sectors.

But the bad sectors are not in the free space, so that won't work.

Clueless.
Find out first what's causing them before you mindlessly replace,
otherwise the same may happen to the replacement drive.

IDE drives

And so do SCSI drives

Which is either a write to the candidate bad sector (i.e. marked
after a previous unsuccessful read) or a successful read retry.

Or just not so real soon depending on the rate of increase and the
number of available spare sectors if the cause is not drive internal.

Wacko, what causes an increase in bad sectors save impending more and then
drive death. Do you recommend looking gremlins and then excorism?

Ignore Ron, most of us do.

The PowerMax LLF also is a diagnostic. It will tell you if the drive should be replaced.

Best to run SMART utility before and save the results. The LLF resets SMART counters.
