[Techtalk] Input/Output Error when reading from CD-RW

[TechChiq]

I put some rather irreplaceable data (including some photos I took of a 
double rainbow) on a CD-RW using K3b. Well, I am not 100% linux as I just 
reinstalled everything and repartitioned (thank you to folks replies on 
how to do that, I think I got it right :) so Windows is no longer on my 
system. Now, the problem is, I insert the CD-RW with my data on it, and 
would you know, I can see the files ok, but neither in Konqueror nor even 
as root in a term I can't copy those files to my user home directory. I 
keep getting an error message about an input/output error.

Did I forget to install something on this installation? According to K3b, 
it looks like most things are instaleld, except there are some other stuff 
that I don't think I had installed last time either.

Please don't tell me the CD-RW is toast! I really can't replace the data 
on it (I know I should have put it on CD-R instead, where I KNOW I can 
read and get the files from it)... I got an ARTEC 48x48x12 CD Writer and 
here's what the specs are from cdrecord -scanbus:

I have ide-scsi passed to the kernel in grub ok (that got done 
automagically), and there is a /dev/scd0 in my system (but even mounting 
that alone didn't work nor did mounting /dev/cdrom). My fstab right now is:

LABEL=/                 /                       ext3    defaults        1 1
LABEL=/boot             /boot                   ext3    defaults        1 2
none                    /dev/pts                devpts  gid=5,mode=620  0 0
LABEL=/home             /home                   ext3    defaults        1 2
none                    /proc                   proc    defaults        0 0

/dev/fd0                /mnt/floppy             auto    noauto,owner,kudzu

and mtab:

/dev/hda2 / ext3 rw 0 0
none /proc proc rw 0 0
usbdevfs /proc/bus/usb usbdevfs rw 0 0
/dev/hda1 /boot ext3 rw 0 0
none /dev/pts devpts rw,gid=5,mode=620 0 0
/dev/hda7 /home ext3 rw 0 0
none /dev/shm tmpfs rw 0 0
/dev/hda5 /tmp ext3 rw 0 0
/dev/hda3 /var ext3 rw 0 0

Does anything look amis? Is there a fix for the i/o problem?
