LS-120 not detecting on boot but after harddrake2

richcoosa19 · 11-06-2002, 11:05 PM

I am running Linux-Mandrake 9.0 and have a LS120 Superdisk drive. Upon booting the system when mounting the local filesystems the display says "special device /dev/hdc does not exist". I get the error until I switch to super user and run harddrake2. After running the program it detects the drive and allows me to mount normally. Any thoughts, I am stumped.

My fstab for the drive looks like this:

-------------------------------
/dev/hdc /mnt/floppy vfat user,noauto,-t
-------------------------------

any help would be greatly appreciated.

Do you have IDE-floppy support included in your kernel? is it a module
that you can load?

Before you run harddrake, run:lsmod

After you run harddrake, run lsmod

Look to see if there are any modules that were loaded that are relevant
to the Superdisk. If there are, you can add that module to your start up
scripts to be loaded before you try mounting the disk.

Alternatively, edit find out which physical device it is:

Code:

hda = Primary master
hdb = Primary slave
hdc = Secondary master
hdd = Secondary slave
hde = Tertiary master
hdf = Tertiary slave
hdg = Quarternary master
hdh = Quarternary slave

(I've included tertiary and quarternary because many mobos these days have a 3rd and 4th controller that can be used for either RAID or as seperate controllers).
Once you've discovered where it is physically, edit your lilo.conf file (or grub.conf file) and in the append section of your Linux kernel, add hdx=ide-floppy... see my example below if you need:

Code:

image=/boot/vmlinuz
        label=linux
        root=/dev/hda8
        initrd=/boot/initrd.img
        append="quiet devfs=mount hdc=ide-scsi hde=ide-floppy hdf=ide-scsi"
        vga=788
        read-only

Before I ran harddrake2 ide-floppy was not loaded, however after I ran ide-floppy was loaded. I edited my lilo.conf file and added the hdc=ide-floppy statement, but the same resulted.???

How do I add ide-floppy into my startup scripts?

Added ide-floppy to modules.conf.

After you edited your lilo.conf file, did you re-run lilo so that the changes are put into effect? You edit the file and then run /sbin/lilo (as root).
