Re: [newbie] Trouble mounting HDC
Schof solved his problem, but I have to disagree with HarM on the
subject of mounting disk.
Mounting the whole disk (i.e. hdc) works for cdrom, not for hard disk.
For these, you can only mount the partition (i.e hdc1).
How would the kernel know where to mount your partitions if you did't
tell explicitely?

Yes, I'm sure...that way you mount the whole disk i.e. all partitions.

HardDrake lists both hda and hdc under the disks drop-down, but when I

I have tried this with two different known-good disks; exact same

Any suggestions for further troubleshooting?
Thanks very much!
You need to edit your /etc/fstab file to let it know /dev/hdc is no
longer a
CD drive The format should be self explanatory. You can comment out
the old
entry with a '#' at the beginning of the line. Then reboot and it
should find
your drive.
If the CD-ROM is defined as ide-scsi, then it is a bit more
complicated. If
your /etc/fstab has no entry for /dev/hdc but does have an entry for
/dec/scd0 then it is ide-scsi The simplest way around this issue is
to use
/dev/hdd instead (The alternative is to rewrite your boot sector
which is
more hassle)

Which makes me think: Could it be that the cd-rom was a CD-writer?
If so there are probably still lines in lilo (/etc/lilo.conf) like append
/dev/hdc=ide-scsi.
Remove those lines from /etc/lilo.conf and run lilo (as su/root) to make it
stick.
Good luck,

Yes the subject of ide-scsi is a bit confusing to a newbie. Your CD-ROM is of
course IDE, but the Linux CD burning backend 'cdrecord' only works with SCSI
devices. So in order to be able to burn CDs with an IDE CD-RW the kernel
supports a 'scsi emulation' mode called ide-scsi.
Now you will say this is a CD-ROM not a CD-RW.
If your CD-RW and CD-ROM are both ide-scsi then it is possible to do CD to CD
copying without having to copy the data to buffer first.
So that is why Mandrake has configured your CD-ROM as ide-scsi.
If you look at /etc/lilo.conf you will see the definition for your boot sector
and you will see in the 'append' line hdc=ide-scsi
Rather than mess about with your lilo.conf file I was suggesting you connect
your hard drive to the IDE secondary slave interface instead. That way it
will be /dev/hdd and you should find that diskdrake will detect the drive and
allow you to configure it.
BTW: The new Linux 2.6 kernel dispenses with the concept of ide-scsi so we may
not see this sort of question for much longer.
