Our Dell SATA 750's say this: # dmesg | grep wd wd0 at pciide0 channel 1 drive 0: <Maxtor 6Y080M0> wd0: 16-sector PIO, LBA, 76293MB, 156250000 sectors wd0(pciide0:1:0): using PIO mode 4, Ultra-DMA mode 5 dkcsum: wd0 matched BIOS disk 80 root on wd0a rootdev=0x0 rrootdev=0x300 rawdev=0x302 They seem to work nicely with the internal SATA disks and Obsd3.7. -- Janne Johansson Sektionen fvr IT & Media, Stockholms Universitet Frescati Hagvdg 10 106 91 STOCKHOLM http://www.it.su.se
