Help with FINDPART

Hi,

I used Partition Magic v8 to move partitions
around on my hard drive and encounterd a
problem when 98% of my linux partition had
been moved. At that point I believe it came
up with a message that there was a bad
sector.

After that I couldn't access the partition.
Partition Magic still sees that the partition
but only the delete, info options are available.

I tried booting from a linux recovery disk
but e2fsck says that the partition has a
bad superblock. I am posting the findpart
output below.

I'd really appreciate it if someone can decipher
it for me and let me know if there is any
way to get the partition back.

The partitions were laid out like so:

Dell Utility
NTFS - Win2K
Extended
linux (ext3)
linux swap

The operation Parition Magic failed on was moving
the linux partition down within the Extended partition.

Here is the findpart output. Any help is
greatly appreciated!

Thanks.

Forgot to add some additional info.

First, this entry appears to be the old
linux partition I intentionally deleted.

0 - 83 8450190 8514450 4157 526 0 1 1055 254 63 B5 3 OK

The size of the linux partition I was moving
was reported in linux as 6.3GB so it appears
that this entry;

1056 2 05 63 13382082 6534 1023 1 1 1855*254 63 --- NB

was the original entry. Why it is a type 05 I'm not sure.
And this entry;

1316+1 83 63 12305664 6008 1316* 2 1 2081*254 63 NB OK

appears to be where the partition was being moved to
except the size is wrong. Also there are several entries
that have the size of 6008 so I'm not sure which is being
used as the current.

Any help would be greatly appreciated! Even if I can only
recover my netscape email that would be great.

Svend, are you around? Help!!!

I am, but I have to be awake too. From the original output:

Disk: 1 Cylinders: 2213 Heads: 255 Sectors: 63 MB: 17359

0 - 83 16964766 12305664 6008 1056 2 1 1821 254 63 B0 3 OK

Before the partition tables are edited, it should be verified that the
integrity of the partition is OK. You could initially try this using
ReadExt2:

readext2 1 1056 1056

But of course the partition table can be edited, and the partition
examined read only.

To remove the partition table entries at cylinder 1316, and add
entries for the 6008 MB ext3 partition at cylinder 1056, you can
download lindsey2.bat in

http://inet.uni2.dk/~svolaf/lindsey2.zip

and run lindsey2.bat, which contains:

set findpart=edit
findpart 1 526 2 - 05 1056 0 1 1821 254 63 526 2213 255 63 26
findpart 1 1056 1 - 83 1056 2 1 1821 254 63 1056 2213 255 63 26
findpart 1 1056 2 - 05 2082 0 1 2212 254 63 526 2213 255 63 26
set findpart=
findpart 1 table fp1-2.txt

Since it is not known if the ext3 partition is internally OK, the
partition should initially only be mounted read only.

It is assumed that the partition tables were not changed since
Findpart was run.

If the partition tables looks similar in Windows 2000, you can run the
batch file using Findpart for Windows, and have the option to post the
content from fp1-2.txt for confirmation before reboot.

Hi Svend,

Thanks for the reply! Your help is really appreciated.

I will move the drive to a system with windows on
it so that I can run readext2. Then I'll post the
results from the command you suggested.

Thanks!

Jerry

Svend,

You are a genius! I cloned the disk using diskpatch(it took
about 8-9 hours but it worked) and ran the find/editpart
script you put together for me.

I can't boot from the disk yet, but when I boot from
a recovery CD I can mount the 6008MB ext3 partition
and see all my files!

grub complains that it can't mount the partition (/dev/sda5)
though because it is a type 05. If you could take one
more look at the current findpart output below I'd
really appreciate it.

Thanks!

Jerry

Nice so far.

There is no /dev/sda5, assuming Linux numbers the partitions in the
first extended partition table as 5. This is because there is free
partition space in the beginning of the extended partition. The ext3
partition then is partition number 6, and the swap partition number 7.

It would be possible to let the extended partition begin later on the
disk, and make the ext3 partition number 5, but I would say that is
outside the scope of recovery. The important thing is if the ext3
partition is internally OK after the PM failure.

Well, I gave up on try to fix grub. Instead I dd'd the fixed partition
from the cloned disk to the original drive. grub then had no problem.
It's good to see my linux partition intact...

Thanks again Svend!
