I shut one of my machines down tonight to have a look-see at its innards. I did my looking around, then started the box back up. The RAID card starts wailing. Poke, poke, poke So, of course one of the (admittedly older) SCSI drives has taken this opportunity to cease to be. It's expired and gone to meet its maker! It's a stiff! Bereft of life, it rests in peace! If it wasn't screwed to the drive tray, it'd be pushing up the daisies! It's metabolic processes are now history! It's off the twig! It's kicked the bucket, it's shuffled off this mortal coil, run down the curtain and joined the bleedin' choir invisible!!
But that's what we have RAID volumes for.

You lose momentum!
And sometimes you can't get it back.
But that's what RAID is for, as you say.
In the normal case, turning off your PC isn't going to hurt anything. If you have power management turned on, you're already racking up several hard drive start-stop cycles each day. In fact, I suspect that by turning your PC off at night you're actually reducing the number of spin-up, spin-down cycles on the drive (because the computer isn't waking the drive up every couple of hours to twiddle something or other). Modern disks are rated for 50,000 to 100,000+ start-stop cycles. So, I'm with them. :-)
