Subj : Partitioning attempt on a Maxtor 120G: wanted both fat32 and ext3

Hello!

I attempted to partition my new 120G Maxtor USB external hard disk
so that approx 20G would be linux and the rest fat32.  The idea was
to be able to back up the linux side, including ownership, etc.

I'm getting the following message:

lion:etc/ ? mount /mnt/maxtor/linux
mount: wrong fs type, bad option, bad superblock on /dev/sda2,
        or too many mounted file systems

What can I do to make things work properly?

Here's a bunch of information on what I did...


lion:root/ ? parted /dev/sda

Using /dev/sda

14946/255/63.  Therefore, cylinder 1024 ends at

lion:cec/ ? fdisk /dev/sda

The number of cylinders for this disk is set to 14946.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
    (e.g., DOS FDISK, OS/2 FDISK)
