Restoring my partition table.

[Jim Wiedman]

I was testing a custom RedHat installation and blew away my partition
table. Not the brightest thing I've ever done.

If anyone could give me some pointers before I try to restore it,
I will be forever in your debt.

I've read Svend Olaf Mikkelsen's pages on partitions which is
extremely helpful, but there is quite a bit I do not understand.


Here's the result of Findpart:

Can I repair this partition table? I'm most interested in
getting at the NTFS partition, but I'd really like to restore the
whole thing.

I'd appreciate any suggestions you can make.

Thanks,

Jim

Partitions according to partition tables on first harddisk:

None.

To add some of the partitions found to the partition tables, you can
download wiedman1.bat in

http://inet.uni2.dk/~svolaf/wiedman1.zip

and run wiedman1.bat, which contains:

set findpart=edit
findpart 1 0 1 * 07 0 1 1 676 239 63 0 1559 240 63 26
findpart 1 0 3 - 83 684 0 1 859 239 63 0 1559 240 63 26
findpart 1 0 4 - 85 860 0 1 1558 239 63 0 1559 240 63 26
findpart 1 995 1 - 06 995 1 1 1062 239 63 995 1559 240 63 26
findpart 1 1063 2 - 00 0 0 0 0 0 0 0 1559 240 63 26
set findpart=
findpart 1 table fp1-1.txt

Only one of the primary ext3 partitions can be restored, since they
overlap. I assume the 1299 MB partition is the current partition.

No partitions were located at the end of the disk. If partitions are
missing, ask again, and if possible give more details about what is
missing, including file system information.

The extended partition is made Linux extended (ID 85). When it is
verified that the logical partitions are OK, it can be made type 0F to
allow Windows to access the FAT partition.

You have the option to post the content from the fp-1.txt file for
confirmation, before you proceed.

Svend,

THANK YOU!!!!!

You restored all of my critical partitions! I owe you big.

May I ask some questions so I'll understand this better the next
time?

How did you know thta the first three partitions were numbered 1, 3
and 4? They were blank in the findpart output. Where does the "26"
version number come from at the end? I expected it to be 42,
matching the version number of editpart.

Once again, thank you very much. I can't begin to tell you how much
time this saved me.

Jim

Svend,

You are welcome.

time?

version number come from at the end? I expected it to be 42,
matching the version number of editpart.

I did not know that, but usually the primary partitions are in
physical order. Entry 2 is unused, because there is free space after
partition 1.

I use 26 as version number for convenience, when no specific option of
a later version is needed.
