Thank you for the patch, with it the drive is recognized with the
following message:
cd1 at ncr1 bus 0 target 3 lun 0
cd1: <HP C4324/C4325 1.27> Removable CD-ROM SCSI2 device
cd1: 3.300MB/s transfers
cd1: Attempt to query device size failed: NOT READY, Logical unit not
ready, cause not reportable
Btw. the HP4020i is a relabeled Philips CDD-2000 with slightly different
firmware. So I would not be asonished if Philips drives would have the
same problem.
