I am seeing hundreds of standby/wakeup cycles on my primary drive, literally every minute, as shown below with a snip from the system log file.
I've tried Power Sav. "medium" and "high" with no change in behavior. Spindow is greyed out for both drives and shows "60" mins.

A disk wakes-up when there is system activity. Period.
System activity can be:
-a running service that needs to read or update info from the disk,
-other computers in the network are refreshing theirs views or status
-competition for memory from too many services running or a memory hungry service.
The most frequent cause are the last two.
The 323 has only 64MB of memory, and it is needed for both a programs code and the data it manipulates.
There is *no control* how a disk is awakened-up, only when it spins-down.
If you force a disk to spindown, and the system needs it for any of the above reasons, the disk will immediately be awakened-up. That is what your system's log shows.
literally every minute, as shown below with a snip from the system log file.
I've tried Power Sav. "medium" and "high" with no change in behavior. Spindow is greyed out for both drives and shows "60" mins.
The Spindown entry grays out when any of the Power Sav mode is selected. Set Power Sav to disable.
Power Sav. is an old APM (Advanced Power Management) facility that many new disks don't support, and it interferes with the normal spindown.
The online help is not very clear about this:
- Power Sav. if the disk supports A.P.M (Advanced Power Management), three levels of power saving can be set. If grayed out, the disk does not supported APM.
- Low: Low power saving, higher performance, can't spindown
- Med: Medium power savings and performance, can spindow
- High: Higher power savings, lower performance, can spindow
- Disable: disables APM
- Spindow You can enter the number of minutes of disk inactivity after which it will enter standby mode, stopping spinning. If services are using the disk, it might not be possible to spin it down. This depends on how the service uses the disk. Also, when packages are installed on disk and are running, the disk where the package was installed might not be put in standby; again, it depends on the service that the package offers. You have to press theSubmit button for this to take efect.
