Problems with Maxtor ATA/100 Card and knoppix 3.9

I am using Knoppix 3.9 to to boot a machine I have with 2-30GB Maxtor drives that are connected to a Maxtor ATA/100 PCI card. The drives do not show up under /mnt but they do show up when I choose DMA Acceleration (I dont want to use it, just wanted to see what showed up). Here's what dmesg shows:

Here is the output from lspci (the Maxtor card shows up as promise)

Knoppix should be able to do it automagically. Out of curiosity, try this code:

Code:

(set -x cat /proc/partitions scanpartitions fdisk -l /dev/hdi fdisk -l /dev/hdj ) >& post.txt

Please post the output from post.txt

I suspect that Knoppix doesn't have the devices setup in /dev/. Try creating one like so:

Code:

(set -x # disk "i" mknod -m 0660 /dev/hdi b 35 0 fdisk -l /dev/hdi ) >& post.txt

Please post the output from post.txt. Does fdisk generate some output? If it does, then you can create the rest with this script:

Code:

# disk "i" # mknod -m 0660 /dev/hdi b 35 0 # already created but included here for completeness for m in $(seq 1 24) ; do mknod -m 0600 /dev/hdi$m b 35 $m done chown root.disk /dev/hdi* # disk "j" mknod -m 0660 /dev/hdj b 35 64 for m in $(seq 1 24) ; do mknod -m 0600 /dev/hdj$m b 35 $[$m + 64] done chown root.disk /dev/hdi*

Let us know how it goes.

I just check on a the Major number on a Fedora Core machine that actually has /dev/hdi. On it the Major number is 56 and not 35. Let's try one more time:

Code:

(set -x # disk "i" mknod -m 0660 /dev/hdi b 56 0 fdisk -l /dev/hdi ) >& post.txt

In fact here's a listing of the devices for the drive and first partition:

Code:

Woo-hoo! Success! Well, at least you can now see the drive and partitions with fdisk.

Right. That's because only one device was made. /dev/hdi is the device file for the entire drive. You now need to make the rest of the devices, at a minimum devices hdi1 through hdi6 which correspond to partitions 1-6 on drive hdi. You can do that with the 'for' loops like so (similar to my previous post but with the Major number adjusted to 56):

Code:

# disk "i" # mknod -m 0660 /dev/hdi b 56 0 # already created but included here for completeness for m in $(seq 1 24) ; do mknod -m 0600 /dev/hdi$m b 56 $m done chown root.disk /dev/hdi* # disk "j" mknod -m 0660 /dev/hdj b 56 64 for m in $(seq 1 24) ; do mknod -m 0600 /dev/hdj$m b 56 $[$m + 64] done chown root.disk /dev/hdj*

or you can do the first six manually by typing this:

Code:

# disk i # mknod -m 0660 /dev/hdi b 56 0 # if already done, you can skip this line mknod -m 0660 /dev/hdi1 b 56 1 mknod -m 0660 /dev/hdi2 b 56 2 mknod -m 0660 /dev/hdi3 b 56 3 mknod -m 0660 /dev/hdi4 b 56 4 mknod -m 0660 /dev/hdi5 b 56 5 mknod -m 0660 /dev/hdi6 b 56 6 chown root.disk /dev/hdi* # disk j mknod -m 0660 /dev/hdj b 56 64 mknod -m 0660 /dev/hdj1 b 56 65 mknod -m 0660 /dev/hdj2 b 56 66 mknod -m 0660 /dev/hdj3 b 56 67 mknod -m 0660 /dev/hdj4 b 56 68 mknod -m 0660 /dev/hdj5 b 56 69 mknod -m 0660 /dev/hdj6 b 56 70 chown root.disk /dev/hdj*

After you've run the above, then run this code:

Code:

( set -x fdisk -l /dev/hdi fdisk -l /dev/hdj rebuildfstab -r cat /etc/fstab ) >& post.txt

Please post the output from post.txt.

That output looks fantastic. You should now be able to mount your drives.

I don't know the really technical details. But I can give you some handwaving details. ;)

In Linux (like Unix) everything is a file: a file, a directory, the screen, the keyboard, etc. Your disks and partitions are also files. In your case the "files" for your drives and partitions were missing. Why were they missing? Probably to save on space to get other items on the CD. So, what you did was create files with mknod. mknod links a device to a file. For example, 'mknod -m 0660 /dev/hdi b 56 0' links the device at Major number 56 with Minor number 0 to the file /dev/hdi. It also defines the device as a block device with the option 'b' and assigns it permissions with 0660. Why Major 56 and Minor 0? I have no idea. It's probably defined somewhere, I just don't know where. Why /dev/hdi? It turns out that that is an arbitrary name. You could name it /dev/my_favorite_drive. But by convention IDE drives are named hd[a-z].

Does that clear things up? Post back if not.

BTW, you will have to recreate those files this every time you reboot the LiveCD, unless you remaster your own CD or use the "save configuration" command and modify the knoppix.sh script. If you would like a hand with either of those, post back.

Glad to hear things are working. And thank you for posting back with your experiences.
