In-Reply-To: <199908171001.MAA20996@yedi.iaf.nl> Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII X-Orig: X-Orig: Sender: owner-freebsd-current@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG Hi Amancio, I've got a: acd0: CDROM drive at ata1 as master acd0: drive speed 1034KB/sec, 768KB cache acd0: supported read types: CD-R, CD-RW, CD-DA, packet track acd0: supported write types: CD-R, CD-RW, test write acd0: Audio: play, 128 volume levels (HP 7200i) which works great. Burning is done via wormcontrol + dd as per Soren's recommendations. Data starvation was never a problem with my old 430Tx based motherboard, but became a problem when I moved up to Asus P5A/ALi board. The solution, it turns out, was to give dd a larger input/output block size - 20k instead of 2k (yes, I used team, and no, it didn't solve the problem ;)). Unfortunately there is no FreeBSD/cdrecord support for this or any other ATAPI drive. I've suggested to Soren that it wbn if his ATAPI stuff was layered under CAM, since this might possibly make porting things like cdrecord a bit more straightforward. As I understand it though the ATAPI spec is such that ATAPI devices can fail in ways that are not currently handled by CAM so this wouldn't be, shall we say, `a piece of cake'. So, as the saying goes beggars can't be choosers, and I am happy with and grateful for all of Soren's efforts. :) To conclude, I like 7200i, the FreeBSD support is reasonable (for what I need), and this device is somewhat cheaper than it's SCSI cousins.
