harddrive

[MechCD]

anyone have a 2gb harddrive? My 2gb quantum is experiencing a "bigfoot spinup" problemn. it thunks on bootup and sometimes won't get detected.



And its not cuz the 853mb drive shorted out :)



I think the heat did it in

EDIT: Turns out the power connector is loose. I'm going to try and resolder it tomorrow

I had an old 2gb fujitsu that had a prob spinning up after power management shut it down.... so i just disabled PM... and then got rid of it in a system i sold(yes i did warn the buyer).... now with gah running on everything the disks don't have a chance to spin down! :D

Amazing. I just signed on to ask a question about power management for harddrives and you're talking about it.

I have a farm of slow desktop computers. I live in California. My electric bill has gone up 3x -- and it would be much less if I weren't addicted to G@H

I've always heard about problems with power managemnt and the simplest thing has always been to blank the monitor but leave the drives running. With S@H, the drive keeps writing every minute or so so there was no point. Now that I'm running G@H on old slow computers, maybe I should be shutting down the harddrives and letting them spin back up every 10% (to update scrlog).

Will it work? What should I look out for? Are the "problems" folks have reported fixed by now?

I run mostly Win98SE, but have one WinME and a couple of Win95. The drives and mobos are almost anything you can think of.

Depending on how long it takes between writes, if its too short, then the hdd will spin up and spin down a lot and might cause wear.











Oddly, my electric bill went down after I fired up my farm :confused: :cool:

Bruce, just how old and slow are these computers? I have my laptop's HD set to spin down after 5 mins, but it never does... it's too active. I run dual clients on all my machines so if one client crashes i don't waste any cpu cycles. ;)

A P133 will run a 65AA sequence in 2h57m and complete the gene in 88h33m. Unless Stefan gives us the capability of NOT writing every 10% to the scrlog, it should take about 18 minutes between perioids of disk I/O. I figure a 99AA would be double that.

A P60 runs a 53AA sequence in 9h36m so it should spin down for almost an hour between 10%'s.

Are those old enough for you?:rolleyes:

I already have a mobo & K6-2-500 for the P60 case when I get some time to work on it but it didn't quite fit so the P60 is talking to the rest of the peripherals right now. It actually finished one gene already.:)

Whoa baby! That takes me back! Don't know thou what you'll save in the end. All you can do is try. The drive will draw more power as it spins up but it shouldn't use that much juice to counter the saving of it being still for an hour. :)
