RE: hard drive won't shut off

One quick way to tell if any partition is currently 'dead' is to do an
ls of each mounted directory (e.g. if /dev/sdb2 is mounte on /mnt/foo,
then ls /mnt/foo)



Let us assume you have 10 partitions mounted, spread all over the
various disks, but they are not all someplace handy like /mnt.



So, for a quick 'hey, is it dead' sanity check, do this:



ls `df -kh|grep -v 'Mounted on' | awk '{print $NF}'`



If you get no errors, it is not QUITE time to panic J



If you do, you probably found the offending partition(s). Also, check
/var/log/messages after that to see if you see any error messages
pointing at a certain drive (even if you don't see any errors in your ls
trick above).



And to the great suggestion of using smartctl (wish *I*'d thought of
it!) - if the drive supports SMART that's the first line of defense -
use smartctl. If not, and the drive is making funny noises, try the
above.

Subject: RE:hard drive won't shut off



On a similar note, my old desktop system, which has several hardrives of
various sizes and ages, has int he last week or two started making on
odd sound that I am guessing is the read/write head being pulled back as
if to power down, then let back out again. It is clearly not affecting
the drive I am running off of, but I do not know of any tool or system
monitor that would help me isolate which drive is going. I must
apologize in advance for having not yet even attempted to research this
on the web. When Mike brought up the general topic, I decided to chime
in and see if anyone remembers something that might be useful off the
top of their heads. If not, I should be able to tell when it goes hard
failure, and it is unlikely to take my main partition with it, so no big
deal. Thanks again in advance for the help.

Mike
