seems to be working fine for me, just add the -d ata line and you get all the
info of a regular ATA drive.
from the smartmontools website:
> Smartmontools should work correctly with SATA drives under both Linux 2.4
and 2.6 kernels, if you use the standard IDE drivers in drivers/ide. If you
use the new libata drivers, it won't work correctly because libata doesn't
yet support the needed ATA-passthrough ioctl() calls. Jeff Garzik, the libata
developer, says that this support will be added to libata in the future. When
this happens, we'll add support to smartmontools for a new SATA/libata device
type '-d sata'. Typically, to force an SATA disk to run using the standard
(non-libata) drivers, you must use the BIOS to select "legacy mode" for the
controller. If the IDE driver doesn't support your particular SATA
controller, or the controller doesn't have a legacy interface, then only
libata can be used. Unless the hard disk controller on the system motherboard
is Intel, VIA or nVidia, standard IDE drivers may not work
> Note: an unofficial patch to libata that allows smartmontools to be used
with the standard '-d ata' device type was posted to the linux kernel mailing
list at the end of August 2004. The patch is included in the libata-dev
patchset that can be applied to a recent Linux kernel (>= 2.6.9). With a SATA
disk driven by a libata driver, smartmontools can now be used by specifying
both the device type 'ata' and the SCSI device corresponding to this disk,
for example, smartctl -i -d ata /dev/sda. The patch is still under
development and it is probably best to make sure that the disk is idle before
that said, if your buying new equipment for RAID, go with a ATA controller
(the HighPoint RocketRAID 454 or 464 seem to have linux support for raid 5,
though the 454 uses the cpu to do parity) and you'll save some $.
