Hi,
This is my first post on this list, so please bear with me.
I've been trying to get a new 64-bit Fedora 17 installation to recognize
an older disk that contains a 32-bit installation. I had installed the
32-bit version on my older Intel-based machine, but recently decided to
replace the motherboard and CPU with 64-bit stuff, and get a new hard
disk for the 64-bit system. I have many files on the 32-bit disk that
I'd like to be able to access on the new 64-bit system, but so far I
have not been able to mount the old disk. I've tried various "mount"
commands with no success. I don't really understand the error messages
when I try to mount the old disk.
Any help will be greatly appreciated.
Below is some information from the 64-bit installation that I think is
relevant.
Here I'm trying to mount the old system:
###########
[root@alan-fedora alan]# mount /dev/sdc /mnt/fedora32
mount: wrong fs type, bad option, bad superblock on /dev/sdc,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
[root@alan-fedora alan]# mount -t auto /dev/sdc /mnt/fedora32
mount: wrong fs type, bad option, bad superblock on /dev/sdc,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
I've already created the /mnt/fedora32 mount point:
###########
[root@alan-fedora alan]# ls -l /mnt
total 4
drwxr-xr-x. 2 root root 4096 Nov 4 11:02 fedora32
[root@alan-fedora alan]# fdisk -l
###########
Here's what "fdisk -l" shows. /dev/sda is not used yet. /dev/sdc is the
old 32-bit installation disk. /dev/sdb contains the new 64-bit
installation.

I think that one thing that's happening is that the LVM software is
getting confused by the fact that both the 32-bit and 64-bit
installations have the same names for the LVM volumes (or whatever the
proper terminology is). But I don't know what to do to straighten out
the confusion.
Thanks,
Alan
