I'm Stumped. Here's my setup:
Primary Master: 80GB
Primary Slave: n/a
Secondary Master: 20GB
Secondary Slave: CDROM

The primary 80GB drive has:
1. A Linux Swap partiton of something like 650 MBs
2. A Single ext3 partiton using the rest of the drive (mounted as '/")

The secondary 20GB Drive has:
1. A bootable primary fat32 Win98 Partiton using 2/3 of the drive
2. An extended partiton containing a fat32 partiton using the remaining space.

I am using GRUB as the bootloader, and can boot into either OS without problems. What I'm trying to do is share the smaller partiton on the secondary hdd in both os'es. I've done this before with no problems when I had both os'es on a single hdd. The smaller partiton is avalible for use as drive "D:" when I boot into windows, but in linux I cant find anything that even indicates that the second drive or any of it's partitions even exist.

I know i missed something. But i'm too tired and blinded by aggravation to see what it is.

Hi Mikester, Welcome to lq. Are the jumpers set properly on the drive and cdrom?
Good luck. ;-)

By any chance do you have scsi emulation set up for the drive?
Good luck. ;-)

Hi Peacedog;
Yes.

Not that I'm aware of. No SCSI devices are present in this system - but based on this output from dmesg I would guess some scsi emulation is being used on the cdrom drive.

The following lines seem odd:

SCSI subsystem driver Revision: 1.00
scsi0 : SCSI host adapter emulation for IDE ATAPI devices
ide-floppy driver 0.99.newide
hdc: driver not present

Not that scsi emulation is being used, but that it's complaining about the driver for hdc not being found. It would appear to me that scsi emulation is being attempted for the drive, but SCSI disk support isn't enabled in the kernel. Why it wouldn't just use the IDE driver is beyond me.

Yeah, I thought that was odd looking too.
So I thought, ok a scsi emulating driver is being loaded for the cdrom drive on the secondary ide channel..mebbe it's screwing up the hdd as well. SCSI emulating drivers are popular (even under windows) for all kinds of devices - most notably cdrom drives and scanners - so I wasn't alarmed by this.
I moved the hdd from the Secondary Master position to the Primary Slave and made the cdrom Secondary Master, and rebooted.
Behold..everything worked. But, why??? And Why did I have to go through hell for this?? Surely something as common as a scsi emulating driver wouldnt cripple a standard ide drive, well not unless it was specifically set to use the same address as the hard drive.


Doh!


Then it hit me. I added the second hdd after I had the linux system running. The cdrom was originally in the secondary master position where I placed the hdd. And good old GRUB never let me forget it.
my /etc/grub.conf contains the following line:

/dev/hdc of course being where I had placed the hard drive. It is now /dev/hdb and I have successfully mounted /dev/hdb2 as my /Storage directory.

[groan]I'm going back to bed now. After I drink this beer.
