Title: Advanced Power Management
Post by: calisun on March 30, 2005, 07:32:25 AM

I have turned on power management in bios, but my hard drive never spins down. Is there something in SME server that I must turn on for power management to work? The issue is not so much power consumption, but premature hard drive failure if it keeps spinning all the time. I know that continues spin up and spin down would increase the latency of the file transfer and is  bad for the drive. That is why I set spin down to one hour in bios. So it would not spin down during the day as users are connected and it is being used, it would only spin down during the night when there is nobody connected. But it never spins down.
Drive that spins continuesly 24/7 would have shorter life span than a drive that spins 10/5.

Another related question, my SME box is used as file server only, but even when all workstations are off, I still notice hard drive light blinks for less than a second every 6 - 7 seconds. Anybody knows what is cousing this?

Title: try looking for logs

start with looking which logs are updated.

Also I do not see a reason for such spindown.
there are some drives that still work after some 6 years of 7/24 work.
not that they have acceptable size for  todays sizes - still - they do work.

Historically any drive in 4 years is completeley outdated (though still useable)

Also I think that the heat is a bit more concern for drive's longevity.
