Getting DPC Watchdog reboot seeming related to sleeping WD Green drives in SanDigital TR4M (JBOD) boxes (eSata MultiPort connections). Win7 seems to be willing to wait for the drives to awaken (which sometimes takes more than a minute), but Win8 seems not to be so patient. If that is the case, won't be able to use Win8 as planned on a new box.
After researching off and on for the last couple of months, getting really confused about these green WD drives. I have 60+ 2TB drives in various flavors (EADS, EARS, EARX, EZRX). Most have developed the symptoms of sleeping and then being hard to wake up. Most are in the TR4M boxes and a (presumed) sleeping drive can disrupt accessing of another drive in the 4-drive (JBOD) unit. All drives have a jumper on 7-8 since they may be used on an XP box too (disable Advanced Format).
Have seen referrence to load cycles & retry values, but not sure where to look & what values would be "bad". Have Crystal & WD DataLifeGuard. Other than the sleep problem, not having problems with the drives and the few that I've checked with the WD diagnostic are reported as ok.
Have seen articles about using WDIdle3 to lengthen park time, but that utility seems to be specific to certain models. Also I don't want to risk my data.
Have seen posts about NoSleepHD, but don't think it will work in my situation since I have 1 or 2 TR4M boxes on at a time (4-8 drives) and then will use HotSwap to "Safely Remove" the drives in 1 box and activate another. NoSleepHD doesn't seem to support that many drives.
Saw How to enable and disable PM2 (power management) on WD SATA drives
How to enable and disable PM2 (power management) on WD SATA drives and wonder if that would help. In the Win Power Options, I have Hard disk Turn off = Never, USB selective suspend = Disabled and PCIe Link State Power Mgmt = Off. The WD drives apparently ignore the Win settings. With this jumper, would I get the "no sleep" that I think I want?
