I'm using a CD drive with no problem until I need to create an ISO
file from a data CD-ROM for what I use this:
# dd if=/dev/rcd0c bs=32k > image.iso
A CD or DVD block is 2k, not 32k.
You may find the readcd(1) tool included with cdrtools more helpful
than dd(1) for reading optical discs.
yep, tried with bs=2k and bs=4k and get same problem.
and that is the intended behaviour of 'dd'. read the manpage.
if the input ends unexpectedly (as it does in your case) you get info
directed at std err - an error.
yeah, I was going to post that the "dd" tries to overstep beyond the
CD-ROM size
and then reports error, but "cdio cdrip" also have problems with the end and
report problems with the last track. Maybe it's a burning issue, i'm
ussing exactly
# cdrecord -v dev=/dev/rcd0c fs=32m file.iso
this is also with DVDs? I'm trying also with DVDs and found that
disklabel shows
a 4.3 GB size of the DVD and "dd" stops before end ( about at 2.2-2.4 GB).
I will try on another PC but I only have problems doing ISOs, so I
discarded the
hardware issue, maybe I was wrong.
