Can't Mount any CD

elkrammer · 07-16-2003, 04:51 PM

I'm using Debian Sid. I have a normal ASUS CD READER.
The kernel detects it as follow:
hdc: ASUS CD-S520/A, ATAPI CD/DVD-ROM drive

But when i try to mount ANY CD(i tried a lot of different cds) i get the following:
~# mount -t iso9660 /dev/hdc /cdrom/
mount: block device /dev/hdc is write-protected, mounting read-only
mount: Not a directory

Then i type dmesg to see what's going on and it prints:
hdc: command error: status=0x51 { DriveReady SeekComplete Error }
hdc: command error: error=0x54
end_request: I/O error, dev 16:00 (hdc), sector 116
ISOFS: unable to read i-node block
ISOFS: changing to secondary root
hdc: command error: status=0x51 { DriveReady SeekComplete Error }
hdc: command error: error=0x54
end_request: I/O error, dev 16:00 (hdc), sector 132
ISOFS: unable to read i-node block

I know the CD Reader is good, cause in Windows it works fine and it can boot my linux and windows cd's fine...

THanks in advance,
Mauricio.

The error says your mount point (/cdrom) doesn't exist. Normaly, CDs are mounted at /mnt/cdrom. Look at/post your /etc/fstab file to see where it was set up to be mounted.

If you want to mount somewhere else, create the mount point on your directory first.

I don't think that's the problem...
Anyway fstab looks as follow:
/dev/hdc /cdrom iso9660 ro,user,noauto 0 0

Probably a long shot but I haven't posted in this forum yet so why not..

create a directory something like /foo (mkdir /foo)
put a CD in and try running this:
mount /dev/hdc /foo

tell us what happens...

You used a trailing slash, so maybe that caused the error.

Try

mount /cdrom

elkrammer · 07-16-2003, 05:36 PM

Blinker_Fluid: I tried that and happened the same:
# mkdir /foo
# mount /dev/hdc /foo
/dev/hdc: Input/output error
mount: you must specify the filesystem type

fancypiper: Same problem:
# mount /cdrom
mount: Not a directory

Of course the directory /cdrom exists..

mount -t iso9660 /dev/hdc /foo

Never seen a CD have that many problems mounting...

You got me, I don't have a DVD drive, so maybe you haven't gotten it configured right yet. Check the Linux DVD HOWTO and make sure it is configured correctly.

What are the hdparm settings? Mine (CD burner):

Code:

root@uilleann  # hdparm /dev/hdd               

/dev/hdd:
 HDIO_GET_MULTCOUNT failed: Input/output error
 I/O support  =  0 (default 16-bit)
 unmaskirq    =  0 (off)
 using_dma    =  0 (off)
 keepsettings =  0 (off)
 HDIO_GET_NOWERR failed: Input/output error
 readonly     =  0 (off)
 BLKRAGET failed: Input/output error
 HDIO_GETGEO failed: Invalid argument
 busstate     =  1 (on)

Blinker_Fluid: i don't think the problem is on my mount command... Anyway i get this:
# mount -t iso9660 /dev/hdc /foo
mount: block device /dev/hdc is write-protected, mounting read-only
mount: Not a directory

I think the problem is on what dmesg prints:
hdc: command error: status=0x51 { DriveReady SeekComplete Error }
hdc: command error: error=0x54
end_request: I/O error, dev 16:00 (hdc), sector 132
ISOFS: unable to read i-node block

fancypiper:

It's not a DVD drive.. it's a normal CD drive...

fancypiper · 07-16-2003, 05:57 PM

You have a data cd in the drive (audoi cds don't mount)?

elkrammer · 07-16-2003, 06:01 PM

Yeah it's a data CD...
I tried many different CD's and it happens the same... the CD's are in good state
