I have used the 2940UW with a CDR100 (!), a CDR400, a CD4260, a CD6416 and a CRW2100 without any problems for years. Somtimes these drives were attached to a 29160.

But: Starting with the CRW2200S, Yamaha started to ship IDE drives with some funky external SCSI-IDE converter attached to them. This is the biggest bunch of sh*t I have ever seen. They do not lock up the bus here but as soon as you do other things on the bus while burning a CD it is quite likely that you get a write error. This applies to the CRW-F1 as well. We have replaced the CRW-F1 with a and everything is fine again. Apart from that, I would use Yamaha writers again if they had a real SCSI interface. -Andre > > I've now replaced the adaptor by a used Tekram DC-390F (15 EUR) and a > new Plextor PX-W4824TA (hum, 119 EUR last winter). > > There are Plextor SCSI CD writers available (IIRC the fastest is the > PX-W4012TS) if you want one, but they're around twice as expensive as > their flagship ATAPI CD writer. > > I'm sure there are other good alternatives for either component (SCSI HA > and CD writer), but I can only talk about those I know first-hand. > > -- > Matthias Andree > > Encrypt your mail: my GnuPG key ID is 0x052E7D95 > _______________________________________________ > freebsd-scsi@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-scsi > To unsubscribe, send any mail to "freebsd-scsi-unsubscribe@freebsd.org" -- Amateurs like Linux, but professionals prefer FreeBSD.
