Thank you for your reply....

My idea is to setup a server where files (music or films for instance)
would
be stored on large disks
which would work only when addressed otherwise they would be down and not
turning.Thus the server could be up but not the disks which could last
longer.

In short kind of an ide hot swap system.

What do you think?

I think you should stop topposting...




Spinning down the disks of a server is a good idea, but only if it's used
infrequently.

Let's put it this way, stopping/starting your disks is going to ware them
out faster. But you do reduce power and noise.

So, set the timeout at a long enought time. Say, 1 or 2 hours.
That way, they will spin down during those periods of the day, where they
tipically aren't used.

should I look deeper into the hdparm to spin down drives etc ?
Deeper than what? There is only one depth to it.
hdparm -S 180 /dev/hda
That sets timeout to 15 min. For details, 'man hdparm'.

...just remember that if a process wants to read from or write to a
disk, the disk subsystem will issue a spin-up command. Since there are
always processes reading from and writing to / and /var (syslog, various
daemons) then your /var disk will either be spinning constantly, or
jumping back and forth between spinning and not spinning. The first
case is better for long-term disk life even if it consumes slightly more
power. It should be easier to spin down disks that are not part of the
core system (not / , /var , /usr , or /home) and have them stay spun
down.
