I'm trying to backup a game CDROM using dd and cdrecord and using cdrdao.
With cdrdao, I get various errors preventing a read of the CD (it's new,
clean etc) until finally, using 'cdrdao copy --read-subchan rw_raw", I get
a 750Mb datafile but the read is interspersed with the following errors:
WARNING: Found L-EC error at sector 7935 - ignored.
The resulting CD, when burned:
[root at valkerie root]# isoinfo -i /dev/cdrom
CD-ROM is NOT in ISO 9660 format
If I use 'dd if=/dev/cdrom of=cdrom.iso' I get:
dd: reading `/dev/cdrom': Input/output error
and a 1.6Mb iso file. I'm presuming this is some sort of copy protection,
[cdaly at valkerie cdaly]$ df /mnt/cdrom/
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/cdrom 670522 670522 0 100% /mnt/cdrom
[cdaly at valkerie cdaly]$ du -s /mnt/cdrom/
A difference of some 40184 blocks between disk size and filesystem useage.
So, given that I'm still entitled to do so under Irish Copyright's 'fair
use' provisions, does anyone know how I can make a backup of this CDROM?
I'm fairly sure that EA Games won't give me a replacement CD when I send
back the original after it's been well scratched after months of the kids'
handling... Well, that's not strictly true.. Their 'limited warranty'
"During such period (12 months from date of purchase) defective media will

Since this CD _must_ be in the drive to play the game, it will inevitably
get scratched (kids being small...). If I don't make a backup of the CD,
I'll have to pay STG7.50 for a replacement (if it's still available...).
I wonder can I claim that the media is defective since I cannot make a
backup of it. And, following on that, I wonder can I demand a perpetual
replacement of defective media since the replacement will not be copyable
