Default HDD suddenly has bad sectors

Didnt think I should, till you got the drive slaved to another, since any
new files will trash it worse

Well say a little more, like names and places where I may view such
utilities.

There are disk utilities that operate on the drive, and rebuild the

files
without the FAT

Well I do have a problem with a corrupt FAT hence my use of Scandisk.
Scandisk has only covered about 1% of C drive partition.

How can I get the data off the disk? If the FAT is corrupted can it be
repaired? Surely the FAT on a partition must be working for the data on

that
partition to be found and moved off to another drive?

I have another computer I could connect the drive to and jumper it to

act
as
a slave. However if the FAT is corrupted how can the other computer

read
the
slave drive?

Scandisk is a file system diagnostic and repair utility, not a disk
maintenance utility. If you run Scandisk and ask it to repair the

file
system while the disk drive itself is still faulty then it will

simply
compound the problem.

Depending on the cause of the problem, it's likely that the more you
use
the disk the worse the errors will get.

You need to get a hard disk drive diagnostic program from the www

site
of
the disk drive manufacturer and use it to determine the extent, and
possibly the cause, of the problem. Once you know what you are up
against you can develop a recovery plan, such as installing the drive
in

a
different machine and copying all your important data off to a
different
drive.

However, I would guess that the Scandisk attempts at repair, and the
length of time that it is taking, has already corrupted the data to

the
extent that there may be little that is recoverable.

Clusters that Scandisk marks as bad are simply removed from the view

of
the file system. They can be ignored when the disk is formatted, and

will
re-appear, unless the format process also marks them as bad..

Whether
or
not they are recovered if you do an image restore depends on the
particular restore you are using - some do and some don't. I would
expect an 'image' restore to ignore Scandisk's bad sector

allocations,
however some restore processes that are called 'image' really aren't.
However, Scandisk attempts to access the bad sectors may cause the

drive's
internal logic to flag the sectors as bad. In this case they become
permanently marked as bad in the drive's electronics and cannot be
recovered.

Hi

Have a hdd which has suddenly developed bad sectors/clusters.

Currently I cannot boot to windows so I booted to the command prompt

and
ran a surface scan dos utility with the auto fix switch.

This surface scan dos utility has been running day and night for 4
days
and has 1200+ bad clusters.

What I want to know is whether the bad clusters it is marking as bad
clusters will be permanetely marked as such; i.e. the hdd will know
not
to use this space again even if I try to restore an image of the
partition?
