Fail more gracefully on unsupported media

[squall38]

cdrskin gets really scary when you attempt to use unsupported media:

---

$ cdrskin data.iso
cdrskin 0.2.6 : limited cdrecord compatibility wrapper for libburn
cdrskin: scanning for devices ...
cdrskin: ... scanning for devices done
cdrskin: beginning to burn disk
Waiting for reader process to fill input buffer ... input buffer ready.
cdrskin: FATAL : SCSI error condition on write : key=5 asc=2Ch ascq=00h
cdrskin: FATAL : Burn run failed
Track 01: Total bytes read/written: 0/0 (0 sectors).
cdrskin: FATAL : Fifo still contains data after burning has ended.
cdrskin: FATAL : 4194304 bytes left.
cdrskin: FATAL : This indicates an overflow of the last track.
cdrskin: NOTE : The media might appear ok but is probably truncated.

How about something like "Media in drive not supported"?

Please try wether the current development version does already fulfill your expectations.

svn co http://libburnia-svn.pykix.org/libburn/trunk libburn_pykix
cd libburn_pykix
bootstrap; configure; make

or

wget http://scdbackup.sourceforge.net/cdrskin-0.2.7.tar.gz
tar xzf cdrskin-0.2.7.tar.gz
cd cdrskin-0.2.7
configure; make

In both cases

cdrskin/cdrskin

is the binary to test.

It should refuse on unsuitable media. Suitable are CD-R, CD-RW, DVD+RW, DVD-RAM and formatted DVD-RW (to be achieved with a run of option blank=format_overwrite). See

man cdrskin/cdrskin.1

I can't reproduce now since I don't have any media that's left unsupported.

That's progress :))

Unsupported would still be: DVD-RW blank (virgin or blanked by cdrecord blank= or by dvd+rw-format -blank), DVD-R, DVD+R, all double layer types, HD-DVD, BD.
