I suspect this has something to do with having 20 drives connected to the system. I take it you are running some kind of server? What drives drop out - internals or the ones in the cages?
Sometimes in these kinds of cases I (personally) like to reset everything to defaults (BIOS - Windows settings) and start over. Sometimes you can just tweak yourself off the rails.
Hang tight - I'm going to turn on the bat-signal.
Hehe, well this is where it gets "hinky" i had a lot of problems with drive dropouts on my old controller,which was a known problem for that controller,and why i bought a new one, the IBM serveraid 1015M flashed to IT mode, which has worked in the sense that the dropouts now occur on different drives from before..
And ALL Drives are in cages,only boot(c), parity(Y) and drive 5(H) and drive 10(M) are connected to mainboard sata connectors, drives 1-4 and 6-9 are connected to my new IBM 1015M, the rest are connected to the asrock SATA 2port pciE cards, and here is where it gets weird
Drive 1 (D) connected to IBM dropout when using drive power management (spindown timer in windows), as does drive 15 (R) connected to one of the asrock 2port SATA pciE cards,and since these 2 drives are not same type drive d is a WD20EARS and drive R is a WD20EARX,it gets weird,and why i am getting grey hairs why this happens.
Mind you, i solely use this "server" for my movie collection,and thus it is only on whenever i want to watch a movie,and i ofcourse could run it with hdd spindown timer set to 0,but there are periods when i run it for prolonged periods of time,and thus would like some sort of power save,mostly to save the drives from spinning full speed when no traffic is needed,and thus extend their life, it is not really because of the few bucks i save on power.
Hope this all makes sense. I know a great deal about pc´s and how they work,but this problem annoys the hell out of me
