I think MAXBLAST wiped my partitions; findpart help anyone?

Help!

I tried to add another drive to my PC, a Windows 98 box. My original drive
was about a 13GB Maxtor drive, the new one is a 40GB Maxtor.

Somewhere during the installation I used MAXBLAST and I think it wiped out
my partition table on the original 13GB disk.

Is it possible to get this back; anyone recommend any tools? I've messed
around with findpart a little bit and have attached the output below.

Many Thanks!

Jesse

The partition table is not quite correct, but it should be working,
and I would expect that you can see the partition from boot to a
floppy?

The begin CHS address is wrong, but the LBA address is correct.

Did you change the partition table manually? No tools I know of would
put 33 in the begin sector field. It should be 1.
 
Sven,

Thanks for responding!

You're correct, I did change things manually with editpart (maybe I
shouldn't have done this!).

I also tried using:

editpart 1 0 1 * 0C 0 1 1 1654 254 63 0 1655 255 63 26

but this didn't work either. I still see an empty C: drive.

Restorer2000 can see some of the folders like "My Documents" but not the
Windows directory. Don't know if this means anything.

I did run your wonderful findpart before I foold around with things too
much; here is the output:

There is no way the partition table in the original message could have
been created using Editpart, since then the CHS and LBA addresses will
always match.
I also tried using:

editpart 1 0 1 * 0C 0 1 1 1654 254 63 0 1655 255 63 26
Correct.

but this didn't work either. I still see an empty C: drive.

There must be some internal damage in the partition. You could hide
the partition by changing the ID to 1C, and then insert the disk as
disk number 2 in a working system. And then copy files using a
recovery tool. If the operating system is Windows 2000, it is not
enough to change the ID to hide the partition.
Restorer2000 can see some of the folders like "My Documents" but not the
Windows directory. Don't know if this means anything.

This also was a working partition table.

It may be possible that the damage is limited to the boot sector, and
that the partition can be repaired, but I doubt it. Some examination
could be made using the Chsdir and Cyldir tools.

This is typical when messing with the parameters in the boot sector (known as
BPB). If you didn't mess too much then there is a chance to restore the
original boot sector from its mirrored copy at CHS 1/1/7. IVINIT from
www.resq.co.il/iv_tools.php will do that automatically on running, provided you
didn't fool around too long with the modified boot sector. Because if you did,
then, the OS would "synchronize" the two boot sector copies (as well as the two
FAT copies).

You can get a second opinion on what happened and on how to approach the
recovery by running RESQDISK /ASSESS, available from www.resq.co.il/resq.php

Zvi & Sven,

Thank you very much for the tips. Per Sven's advice I am having pretty good
luck with Restorer in getting My Documents back. I will try the IVINIT tool
and post the results - although I messed around with things a lot so I'm not
real hopeful.

Thanks again!
