- HELP! Lost extended partition and logical drives
- Posted by Joe on October 19th, 2003
Hello,
First off, OS, = Win 98 SE, Award Bios, WDC1600BB 160GB in 3
partitions, 4GB primary the rest extended with 2 logical drives, D &
E: of 40 & 116 GB. Was using the DLG overlay
I have a 160 MB WDC1600BB which I was using with no problem till about
a month ago. What I suspect happened is that I hit the 137 barrier and
started getting corruption with high ascii characters and eventually
no boot. Quite a bit of corruption on the C: & E: drives, but got most
of my data back and reinstalled the OS and the DDA, which had
disappeared. Also replaced cables and cut back bus speed to 133.
Everything fine until yesterday, when I tried to burn a CD and could
only see high ascii where my D: drive was(maybe that 137 GB
again...had just copied 2 large image files). E: was accessible
Rebooted and now can only see the 4GB primary partition. BOTH the
extended and logical partitions are visible in Partition Magic as
"unallocated" Oh, and the DDA has gone again, and DLG won't let me
reinstall it! the options are blanked out except for "make a boot
diskette" and "update MBR". BIOS reports the disk as 33821 GB. The
data is not critical, but I'd like to get it back if I can.Thanks to
everyone, this is a great group! Here's Findpart(Thanks Svend):

You could:

where the jumpers are on the pins.
Do with no other user programs running (assuming the disk is primary
master):
findpart ide fp-a.txt
findpart setsize pm native expert
findpart pm fp-b.txt
findpart finddir pm 509 550 fp-c.txt
The fp-c.txt file probably will be too large for usenet, but you can
mail me the file.
If the setsize command changes the disk size, it will not be kept
after reboot.
Until now it is known that the first logical partition is more or less
damaged.

recognised the 160 GB natively! This allowed me to undelete one of the

what was the D: is showing as unallocated.. I know this was a pretty
dumb thing to do, but the E: was the most important. Still not good
though....I've checked with partedit and I still have the corrupted
DDO in the boot sector..
I just can't understand why the bios suddenly decided it would
recognise the large disk. When I first got this Mobo, I had terrible
corruption and partition errors which I eventually pinned down to the
PSU(supplying +4.5-6v on the +5). My "current" psu is 4.8-4.9. I'm
beginning to think there is a problem there again. I'll be doing a lot
of backing up tonight.

Looks much more likely that its something else
corrupting the data, not the 137GB barrier.
Unlikely. Much more likely to be a problem elsewhere.

Yes, it is difficult to explain what happened here. Usually there is a
natural explanation, but sometimes it must just be examined what is
present. If the BIOS shows a wrong size, it would normally be because
the BIOS detected the disk at a time where the disk size was limited
by jumpers or disk managers.
From other messages it seems as the MBR partition table is now OK, and
that the partition content is not moved 63 sectors into the disk by a
disk manager.
It should be safe to boot directly to a floppy and do "fdisk /mbr",
but since the current MBR can boot the disk, there should be no need
for that. It has no significance if disk manager code is present in
sector 2 to 63 numbered from 0, except that some partition tools may
complain.

Good, since when the disk already was recognized correct by the BIOS
(according to another message), the command should not be run. (It was
a missing Findpart edit environment variable).
Now we know that the MBR partition table is not disk manager adjusted,
and that there is no Ontrack 63 sectors offset on the disk.
No traces of FAT or directories were found in the first 329 MB of the
expected location for the lost D: partition. Directories and data
usually still would be present later in the partition. It then will be
a FAT32 without FAT recovery situation.

Download lippy1.bat in

and put lippy1.bat on the same boot floppy as findpart.exe.
Run lippy1.bat, which contains:

Note that this will delete the current primary partition, since that
partition covers the entire disk.
After that, you can reboot to the floppy, and look at the partitions
from DOS. Note that the first logical partition should get the C:
drive letter, since there is no primary partition.
You have the option to post the content from fp1-1.txt for
confirmation.

copying a large file near the 137 gb limit and random corruption

48 bit LBA but windows 98 SE doesn't. As I don't have an Intel

safely. Also, I found this while looking for a
solution(http://www.48bitlba.com/win98.htm):
"CAUTION! You may be able to install a 48-bit LBA drive without either
of the above options where it seems that the drive is working at full

corrupted once the amount of data on the hard drive begins to extend

Yep,
Nope, very unlikely indeed to get the specific
symptoms you are seeing due to that.
What's that supposed to mean ? Do you mean the file itself
is that large ? Presumably not because it isnt possible to
copy a file that large on a drive of that size, there isnt room
for both copys that need to be there during the copy.
If you mean that the file is LOCATED near the 137GB limit,
how did you determine where it is physically on the drive ?
You shouldnt be getting 'random corruption' either. It should
be completely non random corruption that affects the bit of
the file thats over the 137GB limit on the physical drive.
Dont believe it. Its MUCH more likely that you in fact have a
drive that has a problem with the cylinders at the high GB end
of the drive and that the RANDOM CORRUPTION occurs when
the file ends up in those cylinders with the bad sectors in them.
You can test that possibility by running a diagnostic on the drive.
That shouldnt produce RANDOM CORRUPTION.
What the hell has that to do with anything ?
That url below spells out how to do it safely with that OS.
That aint RANDOM CORRUPTION, thats completely predictable
corruption when the file ends up in the space over 137GB.
