[comp.sys.mac.hardware] SCSI Saver Compatability...

BRBOYER%MTUS5.BITNET (Bradley R. Boyer) (02/19/91)

   SCSI Saver used to work for me quite well.  I used it when I was
downloading files over night.  I could sleep while the computer was
downloading and then it would power down the drive until I turned the power
off in the morning.

   The program no longer works on my MacSE/030 because of a new feature in the
system document.  The system periodically spins the drive as to keep the
grease from drying out during normal operation.  This was included due to a
common harddrive mechanical problem.  Anyways, I am not sure if there is a new
version of SCSI Saver that deactivates this automatic feature.  As it stands
right now, the system will spin the drive (and move the R/W arm) so that no
parts wear out too quickly.

   Does anybody now if there is another alternative other than SCSI Saver?

I tried SCSI Saver today with my Macintosh II, equipped with a single
internal 40 MB Apple (Quantum) hard-drive.

SCSI Saver succesfully spun down the drive after the specified time
of idle disk spinning, but was unable to reawaken the drive when I needed
it. Folders would not open. Applications would not launch. Every imaginable
disk access failed.

Restarting did not solve the problem. Eventually, the disk-with-a-question-mark
icon came up.

I was forced to power-cycle the machine to get things back to normal.

With my fingers crossed, I tried this three times with various combinations
of applications running doing various things. I was not surprised to see the
same things happen each time.

Anybody know what differences exist among Apple's standard hard-disks? I saw
an earlier posting where somebody with similar hardware was using SCSI Saver
with no problems.
