A little background: I have a dual boot machine with
two scsi disks. The first disk contains XP (sp2), the
second disk has linux (gentoo 2.6.11 kernel)
installed in 3 primary partitions (a small ext2 active
boot partition, swap space, and an ext3 root
partition). Both OS are bootable and work fine. I
want to access this second drive from within colinux
(0.6.2), which is obviously installed on the XP side,
with archlinux (wombat) and the tap driver.

I have problems in mounting the **second disk's**
ext3 partition within colinux (colinux can otherwise
r/w perfectly on the first disk); I can see the ext2 but
not the ext3 fs (the last partition on the second disk)
.
Here's my config.xml:

<?xml version="1.0" encoding="UTF-8"?>
<colinux>
<block_device index="0"
path="\DosDevices\c:\colinux\rootfs_large"
enabled="true" />
<block_device index="1"
path="\DosDevices\c:\coLinux\swap_1024Mb"
enabled="true" />
<block_device index="2" path="\Device\Harddisk1
\Partition1" enabled="true" />
<block_device index="3" path="\Device\Harddisk1
\Partition2" enabled="true" />
<block_device index="4" path="\Device\Harddisk1
\Partition3" enabled="true" />
<cofs_device index="0" path="\DosDevices\c:\"
type="flat" enabled="true" />
<bootparams>root=/dev/cobd/0 devfs=mount
</bootparams>
<initrd path="initrd.gz" />
<image path="vmlinux" />
<memory size="1024" />
<network index="0" type="tap" />
</colinux>

The second disk’s first partition mounts correctly:

# mount -t ext2 /dev/cobd/2 /boot
# mount
/dev/cobd/0 on / type ext3 (rw)
none on /proc type proc (rw)
none on /sys type sysfs (rw)
none on /dev/pts type devpts (rw)
none on /dev/shm type tmpfs (rw)
tmpfs on /tmp type tmpfs (rw)
/dev/cobd/2 on /boot type ext2 (rw)

I can r/w from /boot just fine, I can even
include /dev/cobd/3 as swap space in fstab
(_swapon_ returns no errors, and _free_ shows the
correct increase in space). But the third partition's
fs won't mount:

# mount -t ext3 /dev/cobd/4 /mnt/groot

returns:

mount: /dev/cobd/4: unknown device

I’ve tried to ensure that XP is not claiming this
partition (though obviously it lacks an XP-readable
fs, XP had previously given it a drive letter, which
I’ve removed). Anyone have any ideas on how to
correct this problem?
