Can't read DOS partition

Can't read DOS partition

Post by Karl Schwa » Tue, 18 Apr 1995 04:00:00



I'm trying to access DOS files from Linux but not having much luck.
I have two disks, hda is all DOS and hdb has Linux partitions.  I
have no problems with hdb (a 540 Meg Conner).  I'm running Linux
1.2.1 distributed on the March InfoMagic CDs.

When I boot under LILO, I get these messages:

  hda: Conner Peripherals 170MB-CP30174E, 162MB w/32KB Cache,
       LHS=903,8,46, MaxMult=16
  hda: IRQ probe failed (0)

The disk geometry matches what is in CMOS.  Later in the boot,
the hda1 partition appears to check out fine -- no errors.

In the file /etc/fstab I have:

  /dev/hda1  /dos  msdos  default 1 1

which looks fine and when I run "mount" after booting I see:

  /dev/hda1 on /dos /type msdos (rw)

Just to be sure, I run "fdisk /dev/hda" and see that hda1 is
bootable, Cylinders 1-902, 165945 Blocks, Id 6, and System
16-bit >=32M.

However, when I cd to /dos and do an "ls" all I get is disk
noises and nothing is printed.  A ^C is needed to abort
the disk noise.  Also, I occasionally get errors such as this
when I run a command like (say) "df":

hda: read_intr: status=0x51 {DriveReady SeekComplete Error}
hda: read_intr: error=0x10 {SectorIdNotFound} CHS=0/0/17, sector=0

Needless to say, I have no problems reading the hda disk under DOS.
Also, the LILO MBR is on hda if that makes any difference.

Any help would be greatly appreciated.

Thanks,

-Karl

1. can't read my dos partition

Although I was able to install Redhat 5.0 from my dos partition, I can't

read it from Linux.
I get a "incorrect fs, bad option, bad superblock, etc..." error.  I
used Linux fdisk to change the FAT32 to a DOS 16>=32M.  Is there any
hope?

Thank you
Jonathan
