Hi,

I hope someone has a lead for me......

During CDRom install of RedHat 8.0 I had big probs to use my CDROM or CDRW, so i installed from HDD instead, to get the system running.

The system runs now, but i've got some issues getting the CDROM and the CDRW mounted.

During the boot process it identifies my devices like this:
hda: 80Gb Western Digital
hdc: LITEON CD/DVD
hdd: LITEON CDWRITER

When i login to the system (as root) and try to mount the cdrom from the konsole:
mount -t iso9660 /dev/hdc /mnt/cdrom

i get the following error:
mount: block device /dev/hdc is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/hdc,
or too many mounted file systems

if i do a dmesg i get the following:

hdc: drive not ready for command
hdc: status error: status=0x48 { DriveReady DataRequest }
hdc: drive not ready for command
hdc: status error: status=0x48 { DriveReady DataRequest }
hdc: drive not ready for command
hdc: ATAPI reset complete
hdc: status error: status=0x48 { DriveReady DataRequest }
end_request: I/O error, dev 16:00 (hdc), sector 0

These messages keep repeating......

Anyone an idea to get this thing to Rock ??

Thanks in advance,

Dunno the cause, but I had this once with a cdrom that wouldn't run unless I did "hdparm -d 0 /dev/hdc" which disabled it using DMA. After that it worked fine.

Hi UnSpawn,

Thanx for the suggestion.... but to no avail

Hope someone else can help me ?

Post outputs of

/etc/fstab
ls -la /dev/hdc
ls -la /dev/hdd
ls -la /mnt/cdrom

Is it a combo drive DVD/CDRW?

Thanks for the help,

Thanks for the time everyone......

I've upgraded to the latest stable kernel (2.4.19) and the CDROM 's are mounting like they should......

I think it had something to do with the VT8235 not completely beeing recognised on ide1 with udma.....
