You need an ``override entry'' in scsiconf.c. Most likely:
{
T_WORM, T_WORM, T_REMOV, "HP", "C4324/C4325", "*",
"worm", SC_ONE_LU
},
right after the entry for the YAMAHA CDR100. Let us know if it is
found as worm0 then.
For FreeBSD 2.1, you also need to rebuild your system with the
``options NEW_SCSICONF'' (verify my spelling in scsiconf.c, please).

No idea on this.

As it stands: a unit attention. These drives tend to generate a lot
of them.
I'm afraid you won't be very successful unless you've also got a copy
of the SCSI-2 documentation... Even in printed form, it's not always
very easy to understand.

Never trust an operating system you don't have sources for. ;-)
