mounting problems on 80gb partiton

Ok. I installed a Western Digital 120 GB hard disk as a slave on my machine. The problem is that linux wont mount a large 80gb partion that I made on it. But it's

My bios is old enough to where it can't recognize all that space with out a little help. The provided help is the "Data Lifeguard Tools" that came with the drive.

The last Linux install i did as follows:

I already had my master disk with windows 2000 on it, broken into ntfs and fat (for media type things, so i can work with them in linux)
Next i installed my new hd. Using the Data Lifeguard Diskette i made 3 partions on the disk, one for my / one for my swap and then the big 80 giger for more media stuff. Then i used the DLTs to format that big one fat32, leaving the others unformatted.
So booting into windows, it now sees the fat32 partition.
Next i installed linux (slackware 10) creating a spot for the 80gbs in my fstab, but it won't mount that partition.

The error it gives is the ol':
mount: wrong fs type, bad option, bad superblock on /dev/hdb1,
or too many mounted file systems

Also in my dmesg i see several things that i believe pertain to the partition is question:
I know it recognizes the full size of the disk:
hdb: 234441648 sectors (120034 MB) w/8192KiB Cache, CHS=14593/255/63, UDMA(100)
I know that it sees the partition as i see:
Partition check:
hda: hda1 hda2
hdb: hdb1 hdb2 hdb3 (hdb1 is the 80gb)
There are some errors that i am assuming relate:
FAT: bogus logical sector size 0
FAT: bogus logical sector size 0
UMSDOS: msdos_read_super failed, mount aborted.
FAT: bogus logical sector size 0
VFS: Can't find a valid FAT filesystem on dev 03:41.

my fstab is as follows:
/dev/hdb3 swap swap defaults 0 0
/dev/hdb2 / reiserfs defaults 1 1
/dev/hda1 /mnt/cdrive ntfs ro 1 0
/dev/hda2 /home/media vfat defaults,umask=000 1 0
/dev/hdb1 /home/media2 vfat defaults,umask=000 1 0
/dev/cdrom /mnt/cdrom iso9660 noauto,owner,ro 0 0
/dev/fd0 /mnt/floppy auto noauto,owner 0 0

/dev/sda1 /mnt/camera auto defaults,umask=000 0 0

devpts /dev/pts devpts gid=5,mode=620 0 0
proc /proc proc defaults 0 0

So, yeah. I'm not quite sure what to do. I need to use the DLT in order to get full use of the disk, but i now linux can't mount it. Am i just scewed or does anybody have any ideas?

Much thanks for even getting to the end of this long post!

Don't format with data lifeguard. Don't worry about what the BIOS can or cannot see, except to be sure that your /boot is located at the front of the HD (within the first 540 Meg of the front of the drive...make a separate /boot of maybe 30 Megs, and put it clear at the front). Once Linux takes over, what BIOS sees or doesn't see is irrelevant.

Format and partition the drive using standard Linux tools and it will work fine.

and in windows?

Okay. I had a feeling that the DLT was causing a serious incompatability issue. You think that windows will see things okay?

Do you intend to boot Windows from this drive? If you only intend to use it as a data drive for Windows 2000, there shouldn't be any problem. Windows will see it OK. There can be some issues when you use Linux tools to format a drive that Windows will use; I suggest you carefully review the man pages for sfdisk to get a better idea of how to handle this.

If you wish to boot from it, you will need to be certain that all the Windows boot stuff is in the front of the drive as well. Where just depends on your BIOS; you either have to have the boot stuff within the first 540 Megs or the first 1 Gig, depending on the BIOS. You need to boot to this partition, but you can have your entire Windows installation someplace else; just boot then transfer control.

You may have some issues getting Windows to see the whole drive; in the past I have had trouble (on modern systems with recent BIOS) with WD drives and Win2K. WD provides a utility that helps with this, but truthfully I don't know what level it operates on the system. It runs within Windows so I don't think it messes with partition boot sectors or the MBR, but I am not sure. I have always eventually gotten Win2K to cooperate, but I haven't dealt with the situation where I was trying to maintain dual access between Windows and Linux, so I have to say I don't really know the answer.

Actually, I have to say this. I see all the complaints on this board about problems installing Linux, but in my experience the most obnoxious and difficult to install OS I have ever dealt with is Win2K. It is very often HARD to install. Linux is just slow to install.

Yes I agree. Windows is a major pain to install and maintain. I rarely have had trouble installing linux (excluding getting X to work properly, though i have had fairly good luck with
In my current situation however, i think your plan will work. I keep windows isolated on its own disk so i don't have to mess with it too much, in this case not at all. When i have some time i will back up the little bit of stuff i have on that partition and use cfdisk to reformat it. We'll see what happens from there, but i have a good feeling.

Thanks for all your advise.
