>Description:
It seems the HP 8100 CD-RW drive does not work with the standard
acd driver in 3.x for write mode. When opening for writing, the
acdopen() routine does an ATAPI REZERO_UNIT command that the HP
8100 rejects with an "illegal request" error. The HP 7200 aparently
accepts the REZERO as that drive reportedly does work with the
stock acd driver. The dmesg output for the probe and acdopen()
(with atapi.c DEBUG enabled) are as follows:

acd1: rezero failed
>How-To-Repeat:
With an HP8100 connected, try to burn a CD-R/CD-RW disk. When opening the
device for write, it elicits the following error in dmesg:
acd1: rezero failed
>Fix:
The following patch works for me, but I am no ATAPI wizard so I have no
idea if there are unforseen Bad Things that happen if the rezero isn't
successful.
