[wellylug] CDRW & DVD mount conflict ?

[Adam Bogacki]

I'm confused about mounting dvd & cdrw drives.
I wish to (permanently  ?) mount both so that I can play dvd's and also 
burn audio from CD's in drive dvd.
However, it seems I can't mount both at the same time.

'dmesg' gives me

> hdc: ATAPI DVD-ROM drive, 512kB Cache, UDMA(33)
> Uniform CD-ROM driver Revision: 3.20
> hdd: ATAPI 32X CD-ROM CD-R/RW drive, 2048kB Cache, DMA
> hdd: drive_cmd: status=0x51 { DriveReady SeekComplete Error }
> hdd: drive_cmd: error=0x04Aborted Command


However,

> Tux:~# mount -t iso9660 /dev/dvd /mnt/dvd
> mount: /dev/dvd is not a block device
> Tux:~# mount -t udf /dev/hdc /mnt/dvd
> mount: block device /dev/hdc is write-protected, mounting read-only
>
> Tux:~# mount -t iso9660 /dev/hdd /mnt/cdrw
> mount: block device /dev/hdd is write-protected, mounting read-only
> mount: wrong fs type, bad option, bad superblock on /dev/hdd,
>        or too many mounted file systems


My /etc/fstab includes

> /dev/fd0        /floppy         auto    
> defaults,user,noauto            0       0
> /dev/hdd        /cdrw           iso9660 
> defaults,rw,user,noauto         0       0
> /dev/hdc        /dvd            udf     
> defaults,ro,user,noauto         0       0
> /dev/hdb2       /boot   ext3    defaults                        0       2


Also, I get

:~$ mplayer dvd://1
...<snip>...
Can't open VMG info !

which I understand is due to mplayer looking for  /dev/dvd, but

> Tux:~# ln -s /dev/hdc /dev/dvd
> ln: `/dev/dvd/hdc': File exists


changes nothing.

Any ideas ?
