I have a couple of EIDE drives along with a SATA drive, and the EIDE
drives are only used infrequently.

I'm not sure, but I think my system keeps them spinning.

How would I go about parking them up and suspending them (turning them
off?) while they are not in use?

This on Slack 12.2

Hang on... just found hdparm. Reading the man page now.

Hints, tips, and tricks, still welcome though.

Make sure there's no cron jobs referencing those drives, as there's a
fair delay in spinning up again. And, put them to sleep, but don't
knock 'em out as then you need a power cycle to bring them back :)

Not something I care about these days, HDDs seem to go for years...

I'm thinking about the accumulated cost of electricity keeping them
spinning, and the uneccessary whine in the background, and the added heat
output. These drives are way better than the three I've got in the
"emergency spares" drawer though. I'm saving /those/ for relatives that
"want a computer". >:)

Its kinda fun adding to the list of things I can fiddle with too. :)

Added this to /etc/rd.d/rc.local

hdparm -S 120 -m 16 /dev/hdc
hdparm -S 120 -m 16 /dev/hdd

Lets see how long they keep workin' huh? ;\
