I need help with findpart, below is a listing of findpart results. I am
seeking to restore disk 1 to two partitions, and disk 2 to 1 partition with
correct usage of approx 9M. Had a power surge while loading operating
system. Any help greatly appreciated.

Thanks in advance,

Update: Disk 1 is now OK and all partitions are working fine. Disk 2 is also
visible, but the disk information under XP displays a single partition disk
that is 10.1MB. Disk 2 is actually 20G.

I do not know enough about partition tables to correct this problem. Any
help will greatly be appreciated.

Thanks
 
There's actually (almost) one guy who can help you in this matter:
Svend himself.

I've experienced something similar last Saturday (having problems
during startup while PM was resizing and moving partitions) and the
way he helped me through to get back all my precious data is really
unbelievable! He was even willing to work on his Sunday to help me
out of this problem!

Trying to figure out yourself what it all means is almost not doable.
His analyzing programs are also very powerful. However, you have to
know how to use them!

If you want to play sure, don't mess it up yourself and ask if he's
willing to help you (which I don't doubt...).

In the Google newsgroups, search for his name and you will find lots
of triggers, meaning he's very willing to help people!

HTH.
 
Can anyone provide me with a solution that will restore my MBR to the "BU"
line below? I used findpart to generate the output below and I am convinced
that the second FAT is what I need to repair the hard disk and make my data
accessible. Any help will be appreciated.



Thanks in advance,

I hope the news message did not doublespace, it appeared textual correct
when I posted. Here it is again with only Disk 2 info. It is clear to me
that the end cyl info must be "2433" before I can see the entire disk. I do
not understand why item 11 reports "17", perhaps its the corruption of the
MBR.

If the MBR is set to zeros what restores it?

Thanks,

The 'BU' says your bootsector is missing or bad, probably by something
that caused Findpart to also find the false partition with ID 01.

The # after Root size/Cluster number in FAT output indicate that
your backup boot sector may not be correct either but that could
also be a flaw in Findpart because of that missing original bootsector.

That appears to be your problem, not the FAT(s), that appear to be correct.

the primary partition on disk 2 to the boot sector are:

from pure DOS that the partitions are OK.

You have the option to insert the content from fp1-8.txt here for

I checked the HDD in pure DOS and all looks well. Then I started the XP OS
no complaints. THANKS!

You are a life saver!

Thanks again,

How do I recover/repair the MBR?
Click to expand...

Folkert told you that the BOOT SECTOR, is missing or bad. Not to confuse with
the MBR - these are different sectors, and both are critical.

You can wait for Svend's reply, or you could try RESQDISK.

If the latter, then download RESQ from http://resq.co.il/resq.php, make the RESQ
boot floppy by running the download file and following its instruction, boot
from the floppy, and run from the A: prompt RESQDISK /ASSESS.

Post here the RESQDISK.RPT report that will be created on the floppy (leave it
write enabled) and we'll take it from there.

Partitions according to partition tables on second harddisk:

-PCyl N ID -----Rel -----Num ---MB -Start CHS- --End CHS-- BS CHS
0 1*0C 63 39102147 19092 0 1 1 2433*254 63 NB OK

Meaning that the partition table was changed since Findpart was run
first time, and that the FAT was damaged since Findpart was run first
time.

The partition table error may not be important for Windows XP.

Windows XP may have repaired the FAT again.

I assume you are now in Windows XP. To examine this, you can do:

findpart 2 fp-a.txt

and insert the output here.

I suggest that you do not access the partition on disk 2 until it is
known that the partition is OK.

The 'BU' says your bootsector is missing or bad, probably by something
that caused Findpart to also find the false partition with ID 01.

The # after Root size/Cluster number in FAT output indicate that
your backup boot sector may not be correct either but that could
also be a flaw in Findpart because of that missing original bootsector.

So Svend, does the # in this case mean that the backup bootsec-
tor may be OK because (apparently) it is not checked by FindPart
even though the (original) bootsector is found to be flawed?
Shouldn't FindPart also check the backup bootsector in such case?

The "#" only refers to the boot sector. (Cluster size and root cluster
not confirmed in boot sector).

The backup boot sector probably is OK, but it is not confirmed.

Of course it could be done, but on the other hand it will be better to
check the partition integrity before the backup boot sector is copied
to the boot sector.

One method which can be used to verify if the partition is OK using
the backup boot sector, is this example:

chsdir 2 0 1 1 backupbootsector

I recently made a Chsdir version with this, but it may not be online
yet. Before that, if I would check the backup boot sector, I retrieved
it to a file, and looked at it manually.
