Hi,

I recently installed slackware 10.2 and compiled the 2.6.14.3 kernel. I'm having problems mounting my dvd-rw cd-rw combo drive. Quite bluntly, I'm getting errors regardless of the device combinations I'm using in fstab. Although I'm new with Linux, reading about what I'm dealing with suggests that I need to mount each capability seperately in Fstab (that is, I need to mount both a dvd-rw and a cd-rw for the same device).

The error message I get is either

UDF-fs: No VRS found

or

mount: you must specify a filesystem type

or

mount: bad options, filesystem, superblock
(or something along those lines).


My fstab is listed below. That said, is there a linux command that allows me to view or figure out what the active devices are? I know all the devices are listed in /dev/*, but is there anyway to figure out the devices linux recongises as being active? That would help me figure out the mappings...

Fstab is as follows:

/dev/sda2 / xfs defaults 1 1
/dev/sdb3 /home xfs defaults 1 2
/dev/sdb4 /usr xfs defaults 1 2
/dev/sdb1 /drv-fat_c vfat defaults 1 0
/dev/sda1 /drv-ntfs_c ntfs users,owner,ro,umask=000 0 0
/dev/sdb2 /drv-ntfs_d ntfs users,owner,ro,umask=000 0 0
/dev/cd-rw /mnt/cd-rw iso9660 noauto,user,ro 0 0
/dev/dvd-rw /mnt/dvd-rw auto user,ro 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
proc /proc proc defaults 0 0

not necessarily

all very interesting, but these errors really need to be posted WITH the setttings
you used to achieve them.

will help with disk partitions

might help with dvd/cd but won't tell you the filesystem
(can't think how to do that right now)


/dev/cd-rw /mnt/cd-rw iso9660 noauto,user,ro 0 0
/dev/dvd-rw /mnt/dvd-rw auto user,ro 0 0

perhaps try replacing both these with:

Hi,

Although I did come accross it when I was searching the error messages, I confirmed that the appropriate kernel modules were loaded, and that it should have worked.

Actually, it was your later remark, with respects to fdisk, and the dvd-rw and cdromtool that helped most. It suggested that it should be working but wasn't. I took the obvious route first and decided to first narrow down whether it was a configuration or a hardware error by loading windows and seeing if it worked. When I found that windows, despite recognizing the presence of my drive, wasn't able to access them, I swapped my dvd-drive with that of a friend. The swapped drive worked perfectly under both Windows and Linux.

I got a new drive (the first was under warranty), and everything seems to be working well. It would appear this was the result of a defective drive.

Thank you for your help,

Ps. Clearly I should have included the settings that led to the error message. But I was tired and thought perhaps you could read my mind. Pity I was wrong.

Heh, sorry, my mind-reading skills only work at short range

Glad to hear you found the problem.
