[smartmontools-support]SMART on USB or FireWire mass storage devices

[Rhialto <rh...@fa...>]

I was recently playing with SMART on a recently purchased disk. Then I
built it into a USB2 /  FireWire external box. After that, the disk
changed from wd0 to sd0 (that's how NetBSD likes to call IDE resp SCSI
disks). And, apparently due to the firewire/ide bridge getting in the
way, SMART didn't work anymore.

Which brings me to my underlying question: is there some standard way
for SMART for USB or FireWire mass storage devices that smartctl simply
doesn't know about, or does one exist but my box unfortunately does not
support it, or maybe such doesn't exist at all?

The external box is of the brand Acomdata (www.acomdata.com). The disk
probes like this when it is plugged in:

umass0 at uhub4 port 5 configuration 1 interface 0
umass0: DMI WD3000JB-00KFA0, rev 2.00/2.43, addr 2
umass0: using SCSI over Bulk-Only
scsibus0 at umass0: 2 targets, 1 lun per target
sd0 at scsibus0 target 0 lun 0: <DMI, WD3000JB-00KFA0, 2.43> disk fixed
sd0: 279 GB, 16383 cyl, 16 head, 63 sec, 512 bytes/sect x 586072368 sectors

Hmmm why would there be 2 targets on the scsibus, when the disk shows up
as only one. A "scsictl /dev/scsibus0 scan all all" command doesn't show
anything else either.
