Cannot access Dos partition >1GByte

Post by Thomas Doerfl » Fri, 05 Jul 1996 04:00:00

I am using Linux kernel version 1.2.12. Some time ago I reorganized my
hard disk (SCSI, 2GByte, using Adaptex 1515). It has the following

Partition   Contents
    0       OS/2 Warp Boot Manager
    1       OS/2 drive C (about  80 MByte)
    2       DOS drive C  (about  80 MByte)
    3       Linux Root   (about  80 MByte)
    4       Linux Swap   (about  32 MByte)
    5       Linux /usr   (about 600 Mbyte)
    6       DOS drive D  (about 1200 MByte)

When running Linux, I have the problem that I can mount FAT file
system of DOS drive C, but linux refuses mounting FAT file system of
DOS drive D. In an earlier configuration, when DOS drive D had a size
of about 800 MByte, it worked fine, also using OS/2 boot manager.

Is this a know problem, is there a fix, or should I just try and
shrink DOS drive D? I don't want to reorganize my harddisk once again
(it is so thrilling, is there really _everything_ I need on tape...)
but maybe it is the best way to fix it....

1. Help: Cannot access DOS partition after installing 2.0 & new LILO


Yesterday I installed kernel 2.0 and LILO 19. The installation is successful,
and I can boot my new kernel. However, it destroyed the superblock of one of
my DOS/Win95 partition. Here is my configuration:

        /dev/hda1:      C:, Windows 95 Driver Space 3 Compressed
                        Before compression, ~800M.
        /dev/hda2:      D:, no compression, ~250M.
        /dev/hdb1:      Swap for Linux, ~20M
        /dev/hdb2:      Linux native (everything for Linux), ~400M.

I can mount /dev/hda2 and access the files there, but mounting /dev/hda1
gives the error message like "incorrect fs type or bad superblock". Since
/dev/hda1 is also the bootable for DOS, LILO is unable to boot to DOS also.

When I try dosfsck on /dev/hda1, it says it only supports 2 FATs, but /dev/hda1
has 194 FATs.

When I try fdisk on /dev/hda, partition 1 is still there with correct blcok
size and id, also, with a * to indicate it is bootable.

I don't want to lose my data on /dev/hda1, could anybody give any hints on
how to fix this problem?
