Hi, I'm trying to disable the write-cache on these two disks: <SEAGATE ST318438LW 0003> at scbus0 target 0 lun 0 (pass0,da0) <IBM DNES-309170W SA30> at scbus0 target 6 lun 0 (pass2,da1) both sitting on an Adaptec 2940 U2W controller ahc0: <Adaptec 2940 Ultra2 SCSI adapter> port 0x1000-0x10ff mem 0xd0020000-0xd0020fff irq 11 at device 14.0 on pci0 I can set WCE to 0 using camcontrol modepage -e -m 0x08, but upon reboot WCE is set to 1 again. AFAIK this can't be set interactively, so I am at a loss as to how to disable the wc forever. Any ideas? tks -- pica
