Need suggestions for recoverring data on IBM HD (DTLA-307045)

First let me say I'm just trying to recover as much data as possible.
When I'm done this drive says hello to the trash compactor.

I used it as a second drive in my system (no OS on this drive).
It's divided into four FAT32 partitions with the first being a master
boot partition.

When this drive is hooked up, WindowsXP will not finish booting up.
It seems to get stuck in a loop trying to access this drive. I can
boot up to DOS where I discovered It's only the first of the four
partitions that has gone bad. As long as I don't access the first
partition the other three are readable.

I've search the web and downloaded a few DOS programs and here's what
I've got so far:

HDDTEST - when I ran this it showed 1 error (01000000) and the status
indicator had a red section at the very first and then the rest green.

TESTDISK - indicated a "read error at 0/1/1" with the follow table:

Partition start end size
1 *FAT32 LBA 0 1 1 1401 254 63 22523067
1 *FAT32 LBA 0 1 1 1401 254 63 22523067
2 extended LBA 1402 0 1 5605 254 63 67537260
...lists the other three good partitions...

My first problem is getting the good files and directories transferred
off this disk with their long file names intact. I tried XXCOPY but
ended up with just the 8 letter DOS filename.

Is there a DOS program that will copy directories, files, etc. and
keep the long filenames?

The second question, is the first partition toast or is there a chance
of recovering something off it too.

Before I spend any money for software I'd like to be sure it will
solve the problem.

Any suggestions appreciated

If you have exactly 2 disks in the system.

If the two disk have different sizes.

And the BIOS shows the problem disk as second disk.

You can do this:


Download Findpart for DOS at

http://www.partitionsupport.com/utilities.htm

Put findpart.exe on a boot floppy, boot to the floppy, and do:

set findpart=edit
findpart putsect 2 0 1 1 !zero 5606 00000000 force

The will delete the bad sector in the boot sector of the primary
partition, so you can boot Windows XP and access the other partitions.
Assuming the other partitions do not contain bad sectors and are OK.

It will not prevent recovery of files from the primary partition, but
you will need to know how.

Alternatively you can keep the problem disk powered down, until a plan
is ready. Feel free to mail me about that.

It is assumed that the geometry of the problem disk is CHS
5606/255/63. The Findpart command checks that the number of cylinders
is 5606 to protect against a wrong disk number being entered.

The partition with the bad sector will be shown as "not formatted"
after this. Do of course not format it, if you want to recover data in
the partition.
 
Thank you for responding. This sounds like a plan. But if I do this
the only drive I'll have hooked up will be the bad one (just to be
safe). Would the correct commands then be:

set findpart=edit
findpart putsect 1 0 1 1 !zero 5606 00000000 force

Thanks for your suggestions. Yes I'd like to recover the files on the
first partition.

Yes.

Note that hardware handling also involves a risk.

As Joep will say 8 hours from now, the primary partition could be
deleted in stead, but it may not be possible to delete the partition
using Fdisk.

Since Windows has no read only partition option, and since just
copying files will write to the source disk, the safest solution may
be to initially copy the disk sector by sector.
 
You can hide the first partition and the rest of the drive should be
accessable in WinXP.

Ranish partition manager and most boot managers will hide&unhide.

That's the FAT32 boot sector, it can be restored from the backup with a disk
edtior.
 
But do you need anything from 'c:'? If not, just delete that partition so
nothing will try to read that bad sector, and hook up the drive to another
PC and copy the data.

Another option is to clone the entire disk to another disk and repair sector
(the logical damage) 0/1/1 (which is indeed the boot sector for the first
partition) on the clone.
