QC - 2016-05-01

Been using this for a while now (V 9.43 i think) on a Pi. It has been working great.
however after a recent rebuild I set the spin-down time & power saving factor the same as before
-B 127 & -S 24
now if i execute a manual spindown (-y) the next time the drive is accessed it doesn't spin back up again. It did before?
i'm going to try & remove current ver & go back to 9.43 to confirm.
Anyone any ideas in the mean time?
