Best utility for debugging disk problems

[jthan]

Hi All,

I think I need to find a utility for debugging disk partition
problems. Partition Magic? Others? Here is my story, thanks for any
help:

I just did a clean install of Windows XP (WinXP) from Windows 98 se
(Win98se) and most things are just grand except that I expected WinXP
to recognise my secondary drive, even if I left it disconnected during
the installation. This has not been the case! WinXP can not see the
FAT32 partition (the only one) on the secondary drive. I may have to
back up to Win98 just to get the files off this drive. Note that I
upgraded the bios prior to upgrading the OS.

Some info:

The primary drive is fine. Both are attached to an ATA card on the pci
buss.

fdisk detects the primary partition of the secondary drive.

WinXP detects the secondary drive, but only offers to format it.

When booting with a DOS recovery disk I can see neither drive. (No ATA
drivers?)

I have looked at the disk using the utility from
www.diydatarecovery.com and was able to see the disk as well as verify
that the at least some of the files were there. I was using the demo
version of the utility where you can't change anything, but it appears
that everything is OK, so why doesn't XP mount the partition?

A bit of info on the computer:

Hi All,

To provide more information, you can download Findpart at my page, do:

findpart all fp.txt

and insert (not attach) the output file here.

Here's what I get. Huge thanks for any help. (Next step is to take it
to work and connect it to another computer or something. Or maybe
backgrade to Win98.)

You have to insert the entire output file as I suggested, if I should

Get ****ed. Some of use want to see the detail.

You get to like that or lump it.

The disk size of disk 2 is listed as 2014 MB.

A 19532 MB FAT32 partition was found at cylinder/head/sector 0/1/1.
This is the normal location of a primary partition. From the Findpart
output no problems in the partition can be seen, except that it
currently ends after reported end of disk, and is not in the partition
tables. The partition contains about 12494 MB of data.

The partition table contains an invalid entry for a 2014 FAT16
partition beginning at CHS 0/0/1 (the MBR).

First the disk size problem should be solved. By reading your first
message again, the most likely explanation may be that the disk size
was set using the disk Set Max Address command, but if you have
touched the disk since it worked, it also can be a wrong jumper
setting. If you cannot solve the size problem, you can do using
Findpart for DOS from boot to a floppy:

findpart ide ext fp-a.txt

and show me the output file.



When the size problem is solved, files from the 19532 MB FAT32
partition can be copied to current directory and below using the
command:

findpart chsdir 2 0 1 1 copy

assuming there is room for the files in the destination partition.

It can be examined if the FAT32 partition is internally OK using the
command (when the size problem is solved):

findpart chsdir 2 0 1 1 summary fp-b.txt

If the number of files and number of used clusters from the FAT match
the number of files and used clusters from the directories, the
partition can be assumed to be OK.

If the partition is internally OK, it can be recovered by editing the
partition table. To do that, a new Findpart search should be run when
the disk size problem is solved.

Despite the controversy concerning this discussion, here is the
information. I am quite grateful for anyone who can help with this
problem. I hope that those who are not interested will forgive this
indulgence.

No one ever does except Svend, the author, who is nearly always around.
Any effort by others will go in vain since only Svend knows the specifics
on how his program works (or not works) and what the output therefor is supposed to mean. Trying to help out is competing with
Svend, which one
will loose, so no one bothers.

Some of us are interest in reading Sven's explanations.

You dont have anything better to do under your bridge except play net goon ?

Snapped your dick off did you ? You were warned.
