Do you mean that both traditional IDE drives and these new SATA drives
both begin with "ad" in FreeBSD? I am new to FreeBSD, I have just
migrated from Linux. In Linux, traditional IDE drives used to begin
with "hd" and these new SATA drives began with "sd" and recognized as
SCSI devices. I expected this new SATA drives to begin with "da" in
FreeBSD. Do you mean I am wrong and both IDE and SATA devices begin
with "ad"?
