This looks very good. Actually, I wanted to write exactly such a
program to test all that SCSI stuff. You always seem to be anticipate
my ideas ;). I will check your code and commit it to the repository
into the basictools folder.

So, building it should be analogous to building the SCG version of
himdformat, right?

This sounds great. You should try to convince Joerg to integrate any
possibly necessary patches upstream into cdrecord to avoid a patch
avalanche ;).

On the other hand we still have the problem that apparently we cannot
send any SCSI commands to non-CD/DVD/BD drives on MacOS X. We will
need to patch cdrtools as well, so that it will also work with the
HiMD. When connecting a USB cdrom, the drive is detected by "cdrecord
-scanbus" so it's not an issue with the bus but rather with the drive
type.

Any ideas? Michael was already suggesting that it's a matter of
cdrecord using the SCSI driver from MacOS which provides access to the
optical drives only.
