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.

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

Thank you
