[sclug] Help! CD drive not being seen - more info

[Neil Haughton]

Postscript: lshw also shows the following:

           *-cdrom
                description: DVD reader
                product: DVD-ROM SD-616F
                vendor: SAMSUNG
                physical id: 1
                bus info: scsi at 1:0.0.0
                logical name: /dev/cdrom
                logical name: /dev/dvd
                logical name: /dev/scd0
                logical name: /dev/sr0
                version: F100
                capabilities: removable audio dvd
                configuration: ansiversion=5 status=nodisc

I see the status is 'nodisk', even though I have inserted an audio CD.
Could this mean that the drive itself is the problem?

I'm suffering from Homer Syndrome - I'm pushing so much Windows stuff into
my brain these days in order to earn a crust that my Linux expertise (such
as it was) has been pushed out.Can anyone give me some pointers?

My PC at home (Debian Squeeze) cannot read the CD/DVD drive. I'm not sure
what is wrong but my wife is due to go into hospital soon and I am keen to
get all her favourite CDs into Ogg or Flac format onto her music player
(are you reading this BPI?). So the pressure's on.

Trouble is that I am not sure what the problem is. The drive can clearly be
seen (dmesg and fstabs extract below) , and Sound Juicer has the device
listed as the only choice, but it cannot see the contents when a CD is
inserted.

dmesg:

So I'm not sure where to turn. I also have a CD Writer installed which is
no longer connected because it broke, so I unplugged the ribbon cable
meaning to attend to the problem later. Could it be that just unplugging
that physically has confused the system?

I have some fallback options, such as connect my Windows laptop and make
the CD drive a share and possibly access that as the source, or maybe rip
each ISO image to a file and mount that each time (sounds cumbersome), and
I could also buy an external USB CD drive and connect that, but I'd much
rather just use the drive I already have and have used before.

All and any useful help will be appreciated.

TIA

Neil.
