This is now allright with me, because libata works well. But two other issues remain: How do I - use smartctl on such pseudo-SCSI devices - set DMA to other values?

Previously, my two S-ATA drives had been driven by the IDE driver, and were assembled to a RAID-1 MD device (via software RAID) on them. Now, with 2.6.9, the libata driver takes over, and my md device seems no longer present (booting to an older 2.6.5 kernel, however, makes them visible again). The IDE driver seems not to probe for the S-ATA drives in the first hand: NFORCE2: IDE controller at PCI slot 0000:00:09.0 NFORCE2: chipset revision 162 NFORCE2: not 100% native mode: will probe irqs later NFORCE2: 0000:00:09.0 (rev a2) UDMA133 controller ide0: BM-DMA at 0xf000-0xf007, BIOS settings: hda:DMA, hdb:DMA ide1: BM-DMA at 0xf008-0xf00f, BIOS settings: hdc:DMA, hdd:DMA Probing IDE interface ide0...

The other question is: libata seems to activate UDMA/100 for my S-ATA drives, although they are able to run with UDMA/133. "hdparm" does not work with SCSI drives, in this case. Can I tell libata to activate UDMA/133?
