I've had problems with using two PDC20269's at the same time too. (well actually one is a 69, the other is the 100, not 133 version). They seem to work ok without DMA on, but otherwise I get lots of dma errors when heavy load is placed (such as re-syncing). I've got an Epox motherboard (Duron 1.0 ghz), and four IBM 7200RPM 120gig harddrives. Right now things are running "ok" by having all four drives on one card and the other card (doesn't matter which) in my desk drawer. But it would be nice if I could put it back in the system (the speed was -great-!). -Gryn On Tue, Oct 29, 2002 at 07:08:35PM +0100, Roy Sigurd Karlsbakk wrote: > On Monday 28 October 2002 16:17, Chris Hirsch wrote: > > This is probably more of a hardware question than RAID but since there > > has to be somebody in the same boat as myself.... > > > > I'm trying to do a RAID5 setup with 3 IDE disks connected to IDE1/IDE2 > > on a Promise ULTRA133 TX2.
