help - lost dos partitions while installing linux

Post by Paul Maynar » Wed, 07 Oct 1998 04:00:00



befor i started i had:
win95 on the first primary partition,boot manager, and 250M free space
before an extended partition
on the extended partition i had a linux swap partition and ~1gig slackware
linux; another 1gig free space; 3 dos partitions; 2 hpfs partitions;1 more
dos partition; and another 500M free space

during suse install i deleted the 2 linux partitions, then the install
prog. asked if it should install on the 2 gig of free space, i say yes,
the install program attempts to create a swap and root partition and then
reports a mke2fs error. after this my dos and os2 partitions are gone.
anyone know if i can recover these? since i don't think they were
formatted can i create partitions exactly where they used to be and be
able to recover the data?

thanks for any help

If you know exactly where they are supposed to be, and if indeed they
have not been touched, then yes, you should be able to repartition the
same way and have them back.  But you do have to know exactly where the
partitions used to be.  None of us knows where they were.  Since the MBR
has been written over, there is no way to find out now.

Hello Paul,

||  If the data was untouched (only the partition tables), then:

^^  yes, that is exactly what you need to do.  What you need to
know, is the exact sizes and placements of the partitions.  If
you need help, post further details here.  A partinfo.exe report
would be helpful.  Partinfo is a utility included with Partition
Magic, but is also available as a free download from the PowerQuest
site.

help - lost dos partitions while installing linux

Post by paul mayna » Tue, 13 Oct 1998 04:00:00


i have been trying to recreate them using mikhail ranish partition manager. once
i enter the information where i think the first lost partition exists, partition
manager seems to recognize automatically the rest of the partitions. however the
volume labels don't show up. another person who used partition manager to
recover lost partitions told me that the volume labels should also reappear. so
i am not sure i have the correct values. i have also tried the linux program
fixdisktable. while it was able to find a linux partition that i had deleted it
has not found my fat16 aprtitions.

here is my partinfo report:

At the end of this post I have shown in table format what your partition
tables would currently look like, based on your partinfo report.  The
Windows primary, Boot Manager, and extended partition all show up, but
there is no 250 MB free space before the extended partition.  Then, three
Linux partitions (swap, native, native) show up.

Thus spake pmayn...@bcpl.net (paul maynard) in message <3621735f.3057...@news.abs.net>:

That's a good sign.  Does it recognize *all* of the original partitions?

The volume labels do not show up _where_?  Do you mean in Ranish Partition
Manager?

The values were _likely_ correct.

Ok, so where did these three Linux partitions come from?  Are they new ones
you created, or former ones you restored with Ranish Partition Manager?  You
said Ranish Partition Manager recognized the rest of the partitions.  Did
you then undo the recovery you had done with Ranish?  If so, could you redo
the recovery and then post a new partinfo report, and let us know why you
felt that Ranish had not done a proper job?

help - lost dos partitions while installing linux

If you create a fat32 partition with the same starting and ending cylinder
numbers as the original, it should still be good.  You can only do this
with the linux fdisk; do not attempt it with the ms fdisk.  You'll need to
give it a type designation of 0b.

Fogive me for not testing this, although I have done it with other
partition types.

1. HELP! Lost Xtended DOS partition while installing Linux...

Hello,

Last night I tried to install the latest Slackware version of Linux
(from ftp.cdrom.com) but something happened to my D: drive which was
set up as an extended DOS partition.

I had loaded all the Linux install disks on D: in directory \install.
After running 'setup', I tried to install from hard disk but kept
getting errors.  

I rebooted my computer in order to copy the \install files from D: to
C: but I was no longer able to access D:!!  I got the dreaded
'abort, retry, or fail' message...

DOS fdisk lists D: as still an xtended partition but its System type is
unknown.

Linux fdisk lists what was D: twice as sda2 and sda5

/dev/sda1   *     1   1 300 307184      6       Dos16
/dev/sda2       301 301 400 102400      5       Extended
/dev/sda3       401 401 503 105472      83      Linux native
/dev/sda4       504 504 520  17408      82      Linux swap
/dev/sda5       301 301 400 102384      6       Dos16

I have a Seagate 520 MB SCSI hardrive with an Adaptec 1540C controller.

Is there anyway to recover data off D:? Or is it lost forever....

E-mail if you can.  Thanks in advance!

-Kenny Quon
