Comment 14 for bug 1281588

Rocko,

Slightly OT

I see a variety of behaviour., based on the disks.

On 14.04 with the 30min polling patch: If you set the spindown to 15 mins and poll at 30, all of my disks spin down and stay down ( see list above).

 If you set the spindown to 5 and polling to 10, I have problems with the WD not being able to be set to less than the polling frequency ( as discussed original problem).

However I also see problems when poilling is within 1-3 min or so of the spindown on the Seagate drive. I havnt tried to work out exactly whats happening, or exact timings . But the seagate doesnt seem to cache anything hdparm doese either. so hdparm -C will wake it.
In summary, The 3 samsung drives stay down, but the seagate spins up if polled too soon after its spindown.
