Hi net gurus!! I have a question regarding the Mac IIsi hard drive and figured that somone on the net would have the answer. It seems that my drive has a power-down "feature" as it shuts down after about 2 minutes of inactivity (of the drive, NOT the mac). Is this normal? Should the timeout be this short? Better yet... How do I disable this "feature" completely? It reduces the effective speed of the machine, since I am constantly waiting for the drive to spin back up. Thanks Rick Klaus rickk@hp-vcd.hp.com P.S. I did look through the manuals and can find nothing about this.

There is an init called SCSISaver that does just what you described. Check
you System Folder and see if it is there. No, it is not normal for a hard
drive to spin down after 2 minutes. Your problem must be caused by
something added to the standard system (i.e. the system sw as it come from
Apple does not support any kind of SCSI spin down), -OR- may be a hardware
problem. Does the hard drive spin back up if you access the drive? Hope
this helps,

I would like my drive to power down after about 10 minutes of inactivity and have been looking for a way to do this. Does it work with any drive?

My understanding is that the most dangerous time for a HD is power up and power down. (Other then solid jolts whilst spinning). This is because on some drives the heads come down and rest on the surface, or have to be retracted by the drive as its power dies. Drives last longer when they are left to spin. -- | Michael Harlow | u855203@bruny.cc.utas.edu.au | | GPO Box 1201, | u855203@probitas.cs.utas.edu.au | | Hobart, 7001 | Computer Science Department, | | Tasmania, Australia | University of Tasmania. |

For the Portable there is a CDEV utility that lets you select the amount of time on drive inactivity before the drive shuts off. The MacPortable uses Connor mechanism and I think that their drives are made to handle being turned on and off regualarly. > My understanding is that the most dangerous time for a HD is power up and > power down.

You can get scsisaver via anonymous ftp from mcsun.eu.net.

The reason that the HD spins down on the portable is to save battery power I can't think of a good reason to keep turning the HD on and off on a desktop machine except when it's going to be moved.... Steve Fuller XDPQ8@vaxf.cc.iastate.edu

A friend of mine bought a IIsi, when he got it the internal 80Mb drive was defective, so he took it back and had the HD replaced. When he got the mac back it had the same "feature" you mention. The "repairman" told him that he replaced his HD with one from another IIsi, 80Mb low profile HD's being in short supply at the time. Eventually they replaced the HD again and the "feature" went away. Incidentally, his HD would spin down after one minute, almost to the second, of inactivity.
