It’s clear that FreeBSD is proactively disconnecting the drive when the timeout occurs. So, maybe there’s something that can be done there. Hello. While I cannot disagree with this last sentence, I've had my share of troubles with WD Green drives too. I had to replace them more than once during their warranty period, and was almost happy when they finally broke after the warranty was over. Leaving that aside, these drives will power down if not used for a while, but there is a DOS utility which can disable this feature. Not only this will avoid an even shorter lifespan, but it's an essential procedure if you want to use them with FreeBSD. If you haven't done this, then do it. After doing that, I was able to use them with some controllers, but not others, so YMMV. Finally, upgrading from 7.x to 8.x and then 9.x helped a lot, but in your case I don't know if there is any improvement after 9.2. HTH. bye av.
