Hi,
I have a WD external USB harddrive which I use for backups. How can I
check the drive? Is it possible to use S.M.A.R.T (is it supported on USB
drives)? As it is my backup drive I'd prefer to know if something's going
wrong.
The drive is encrypted with luks, automounted by hal. I use Debian sid,
Gnome.
S.M.A.R.T. doesn't work on my external drive. Try the docs from
smartmontools, they have some information about this.
Is it a SATA drive?
It's connected to the computer via USB, same as OP's. I don't know how I
could tell what it uses internally, but I doubt it matters because
AFAICT it's a limitation of the USB interface.
Well, I bought 2 of those Venus enclosure boxes. Let's see:
http://www.newegg.com/Product/Product.aspx?Item=N82E16817145657
One for a ATA hdd and one for a SATA hdd. Then I bought an oem ATA and a
SATA disk: an ST380211 and an wd80_0jd-60 and put them inside the
enclosures and connected them.
They work fine, show up as sda and sdb.
But *with the Debian kernel* I can do:
smartctl -d sat /dev/sda --all -T permissive
and get an answer. But when I try that with sdb, I get the answer that
the disk is not smart enabled.
Now, when I roll my own kernel (which does not have near the same
.config as the Debian one) I get that neither disk is smart enabled.
So bottomline seems to be that smartctl *is* dependent in the kernel
config *and* what sort of drive is involved and how.
