freebsd stable - Apr 2005 - Adaptec 1210 weird behaviour

The Adaptec 1210 is a serial ATA RAID0/1 controller.

When the two disks are configured as RAID1, FreeBSD still sees two
harddisks instead of one.

This is with 5.3. Scary :-)
Will try this weekend with 5.4

The 1210 is not a real RAID controller, it's a SATA controller with an
Adaptec BIOS that does RAID 0 and 1 during boot.  It's up to the OS to
do the RAID operations after that.  The new ATA driver in 6-current
might actually be able to handle this, so it's worth trying.  5.4
definitely will not.
