        Hi Russel, Trent
I'm using an external ESATA, system have been for a number of years. When I first started out the Linux kernel did not support SMART pass-though for SATA, but it did shortly after I started using the system.
smartctl -d ata -a /dev/sd[abcdefghijklm]
just works :)
FWIW, I haven't found any devices in the last few years that don't work with smartctl, even if they require a bit of tinkering with the -d option to make it work. James
