Any further ideas how to get rid of this feature?
You have several options.
1) The most clean solution is probably using the WDIDLE3 utility on
your drives to disable automatic parking or in cases where its not
possible to complete disable it, you can adjust it to 5 minutes, which

I've upgraded the firmware at five WD1000FYPS disks. One of them

I would really prefer to be able to set this stuff via camcontrol or

Hi all,
After being disturbed by the firmware issues of the wd drives causing
exceeding load cycles (see thread immense delayed write to file system
(ZFS and UFS2), performance issues in January), I have found some more
problematic drives in the following setup:
