unable to mount the cdrom
|

| No Spam 2004-02-25, 3:34 pm |
| I wonder if anyone has had a similar problem and what they did to rectify
it.
A few weeks ago my cdrom on redhat 9 was working fine, I then increaed the
ram, after placing the ram module I was unaware that in the process I had
dislodged the ide cable for the cdrom, when I rebooted the cdrom no longer
worked, I opened up the comp to find the ide cable dislodged and promptly
put it back in place.
However the cdrom works by manually pressing the eject button on it apart
from that it looks like linux no longer recognises it, on start up it says
/dev/cdrom failed no such file or device. All previous mount commands no
longer work it just says /dev/cdrom no such device or no such ... in
/etc/fstab or /etc/mtab. I am at loggerheads over what to do, I am very new
to linux and am wondering is dislodging the ide cable and powering up the
comp could have permanently damaged the ide cable, here is my last dmesg
log any help will be greatly appreciated.

At least the CD-ROM has power and some of the firmware is OK.
<snip>
Here's the information about your primary IDE interface channel only,
notice no secondary IDE channel is listed;
> ide0: BM-DMA at 0x7cd0-0x7cd7, BIOS settings: hda:DMA, hdb:pio
..........
> 0x1f0-0x1f7,0x3f6 on irq 14
Primary IDE Channel example;
ide0: BM-DMA at 0x1860-0x1867, BIOS settings: hda:DMA, hdb:pio
Secondary IDE channel example;
ide1: BM-DMA at 0x1868-0x186f, BIOS settings: hdc:pio, hdd:pio
Example IDE I/O ports and IRQ assignments for both IDE channels, primary
on top;
kernel: ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
kernel: ide1 at 0x170-0x177,0x376 on irq 15
Things to check;
Check your system BIOS and make sure the second IDE interface channel is
not disabled. Most of the time the CD-ROM is attached as the master device
on the secondary IDE interface channel (dev/hdc in Linux terms).
Make sure that the IDE cable is in fact connected properly (maybe it's not
fully seated) and not backwards (in most cases the drive light stays on
all the time).
The CD-ROM may be OK, the cable might be bad or the secondary IDE
interface channel is 'blown out' on the motherboard (this happens often).

Sounds like the IDE interface on the mother is not well, it might be time
to think about a replacement, sorry.
