> I have a WD10EARS which lies about its sector size Some further information: I'm using the sdata driver rather than sdiahci because my motherboard doesn't support ahci. This may be why I'm seeing the disk as having 512-byte sectors not 4096.
You could try telling your BIOS to use the disk in ATA (IDE) mode, and see if that gives you 512-byte sector emulation. However I seem to recall posts from Erik advising that some chipsets have bugs in this mode which affect Plan 9.
