Error whilst copying from Dvd Drive:

i'm using suse 10.o.

The problem I'm having, is that when i try to copy a file from a CD to my hard disk i get the following error:

Error "I/O error" while copying "/media/dvd.../".

It will copy around half the file, then the drive seems to stop spinning and i get that error?

Any idea what the error means, and how i can fix it?
thanks in advance!

some info. on the drive:

Does your DVD player handle other media correctly?
Is it possible that the Data file is corrupted in someway?
Is the media clean and unscratched?
How Large is the file? How much RAM do you have? Have you performed a memory check on your RAM?
Have you checked any of the connections in your box, IDE cables, SATA connectors etc?

I could be mistaken, so don't take my word as gospel. However, on examination of your fstab and mtab, I see one discrepancy.

As I understand it, to access files on a data cd, the device has to be mounted (from fstab: /dev/hdb /media/dvdrecorder).

Mtab shows the currently mounted devices, and mtab does not list /dev/hdb.

Perhaps that's the error. You haven't mounted /dev/hdb before attempting the file copy.

If your hardware checks out OK, I found this whilst browsing. It may be useful to you. It contains info on how to recover data from possibly damaged CD's using the dd command. Worth a Try,
