Thanks for the correction.
I looked at the fan, and it's a 12v one ... So, the ATA drive and the fan are running off the YELLOW, 12v wire ... not the RED 5v one ...
Basic computer electronics: If you put the fan's power lead to the 12V wire and the fan's ground lead to the 5V wire, the fan will run at seven volts; about half speed but also half noise. It's perfectly safe and a common tactic used on custom-built computers. (Just don't put the power lead to 5V; then the fan won't have enough juice to spin up!) If you've got a front drive bay open (5.25" preferred, or 3.5"), you can buy a fanbus to control the speeds of your fans, if noise is a problem. (Recommendation: DigitalDoc 5+)
I may just forget it ... a bit afraid of fracturing the electrical system of a sensitive machine ... may blow something out that would end it all ... switching something on and off may cause a bad flux of some sort ... especially while the system is up ...
Probably not; hard drives can be configured (at least on PC's) to shut off after a certain period of inactivity. It really isn't worth it; it's more stressful to power up and down than it is to keep running. Plus, an "idling" hard drive doesn't use too much juice anyway.
These ATA drives, by Seagate, are good ... but they don't last like my older Seagate SCSIs did ... and still run!
I just had a three-year-old Seagate ATA fail on me a few weeks back (model ST360021A). It was part of a RAID 0 array of which I had no backup... Probably just another isolated incident; I wouldn't be concerned. Just remember to keep a backup.
