Cannot read discs
I have a little problem. See, my computer won't read some discs.
It doesn't matter if they are DVDs or CDs, they just won't read.
I mean, I put them in the drive, the drive spins up and everything, but Mandriva just doesn't mount it. Nowhere can I find that disc.
I put a disc in 5 minutes ago, and now I can hear it, trying to read it. These are discs that previously worked, back when my computer was running Windows, so I know that this isn't a hardware issue. Mandriva just doesn't read them.
Hi - if you open a terminal and type 'mount' what's your output? Here's mine for example:
fingal@pickle> mount /dev/hda1 on / type ext3 (rw) none on /proc type proc (rw) /dev/hda6 on /home type ext3 (rw) none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)I am always doing that which I can not do, in order that I may learn how to do it. - Pablo Picasso
Here is my output:
/dev/sda1 on / type ext3 (rw,noatime,commit=0) none on /proc type proc (rw) /dev/sda6 on /home type ext3 (rw,noatime,commit=0) none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) none on /sys/fs/fuse/connections type fusectl (rw) //UBOX/mydocuments on /home/mord/smb4k/UBOX/mydocuments type cifs (rw,mand,nosuid,nodev,user=mord)
I suspect that Mandriva is not mounting the discs, because I hear the drive. It is making little noises, I can't exactly explain it.
Let me see.... a disc drive has 2 movable components: the part that spins the disc, and the part that moves back and forth with the laser LED on it.
When that part moves, it makes a distinctive sliding noise. THAT is what I am hearing. That part moving back and forth a couple of times, the spinning thing for a second, and then again.
Hmm - your drives are mounted all right. I see you're using SCSI drives... I don't know much about those but I think you need a driver which might not be loaded. If your kernel is looking for the correct drivers then your disks will spin, but not much is going to happen!I am always doing that which I can not do, in order that I may learn how to do it. - Pablo Picasso
What are SCSI drives?
And where/how do I get drivers for them?
Actually what I said was slightly misleading, as your hard drives are likely to be SATA.
You mentioned that you can't read some disks, but can you play any CDs? You don't need to mount them manually, and although the Linux kernel knows about your devices it handles then discreetly.
DVDs are a different case, and to play those you need separate drivers to read the disks.
Sorry about the short reply.I am always doing that which I can not do, in order that I may learn how to do it. - Pablo Picasso
I can read DVDs, I have libdvd something or other. I have been able to read a store bought DVD.
But a disc that I burned (backup files and such) won't show.
Might it be because those discs were burned using Nero on Windows?
Actually, it's a pretty random event.
Some discs will read, while many others will (consistently) not.
I find it very hard to believe that two thirds (up to a certain constant) of my discs are defective or decaying.
Whatever the case, if you can read these CD's in Windows then I would suggest that you back-up these files if you need them.
