Yeah, I have 2 wd 'black' consumer grade drives fixed with WDTLER paired with some seagate ES drives right now. (I mix makes to avoid firmware plagues) I read that WDTLER only works on 1TB and smaller drives. I will have to find some 1.5TB WD drives and experiment.
As for the relation to ZFS, it is supposed to timeout ill-behaving consumer drives like this. In fact, from what I understand, you can configure ZFS's behavior, for example, to fail the first drive that times out, and then hang on the second drive (which would perhaps be a reasonable configuration for a ZRAID volume)
