Comments:

Took a while to get working due to lack of docs, i.e. transport info and nothing else! Thanx Yamaha! This drive is an excellent piece of kit. 646mb Data track at 4x speed in 17mins! No problems encountered. Seems to enjoy any writable CD's up till now, very easy to feed ;-).

Comments:

Nice 10x CDROM, works perfectly but doesn't like CD's with sticky labels (low clearance in drive). Reads CDDA.

Hard disk:

Seagate ST3144A 130 MB HD as boot drive.

Comments:

This is what I am stuck with at the moment. It works, but the maximum transfer rate I could achieve was 357KB/sec. This is just a bit too slow to be able to write in 2x speed. At the moment I am using Reselection off the writer, DMA on the Host adapter, 32kb chunks and sequential writing with a 12MB buffer while writing in only 1x speed, very disappointing after buying a 4x CD writer :-(.

Tips:

Not many, it works (mostly) but you should always, ALWAYS write the WHOLE CD in test mode first. I have a very nice collection of "coasters" now so if you want to buy a "CD clock" as a present for someone you don't like, or a frisbee for the kids, I'm your man ;-).
