Early 2011 Macbook Pro, OWC Datadoubler with Sandisk Extreme in the orignal slot for Sata-III, and original drive in the optibay. I'm not sure if my problem is the same as everyone else's regarding spin down; my disk won't stop writing/reading. Mostly writing however, and it seems to be at about 10 second intervals. I've killed spotlight/mds/mds worker, Istat, and set sleep to 3 minutes, but as I keep getting regular write spikes, the drive won't sleep, then it will go crazy writing for no apparent reason (no applications running, not doing anything but watching the monitor) The setup I have is having a boot-admin on the SSD, with my user folder pointed to the optibay HDD for my actual user. Any ideas?
