Right Now I'm using hdparm command in unix to shut down the hard disk but there are few issues with it.

when it wakes back up it consumes lots power. Is there any other way to do it?
Many times when I put my hard disk to sleep, I can see few bursts at the beginning and then after a while it goes to sleep. I think its because of the journaling system in ubuntu (which I use) Have anybody encountered that?
What would be the best linux/unix operating system (eg: ubuntu/centos/redhat) to work on extensive hard disk operations?

I would highly appreciate if you could share the problems you encountered while doing this operation.
