My primary hard disk and controller are an ST4144R disk and a WD-1006vsr2 controller. The only trouble I've had is the notorious lock-up problem. I've cured this by formatting 2:1, so I lose a little speed but it's a lot better than crashing (anyway I've got a 209 Mb SCSI as my other drive :-) ). ESIX does detect that the primary drive is RLL. That's ESIX rev. D - the only version I've used. Cheers, Glenn > -- > Mark A. Emanuele > V.P.
