<my long post snipped>
If your disks aure ultra 160, you should have 160 MB/s DT
Something looks wrong in your hardware, - are your disks LVD enabled ? - do you have ultra 160 capable cables and terminaisons ? - are your terminaisons correctly configured ? - do not connect other SCSI devices on the same scsi port, - never mix 16bits and 8bits devices.

Thanks Michel - the dmesg quote was part of the original post though - things don't look so bad now I've got the cabling right. I originally copied the cable installation from the machine I extracted the card and disks from, rather than looking properly at the installation manual - which means I messed it up. But I've put the cable back where it goes now. Things are now better - sorry if my second post wasn't making that clear, I should have deleted that old part perhaps.
