If I'm not mistaken then the WD2002FYPS is an enterprise model: WD RE4-GP (RAID Edition, Green Power), so you almost certainly have the firmware that allows (1) the idle time before spindown to be modified with WDIDLE3.EXE and (2) the error reporting time to be modified with WDTLER.EXE.
So I expect your drives are spinning down to save power as they are Green series drives. But if this spindown is causing odd things to happen you could see if it's possible to increase the spindown time with WDIDLE3.EXE. Let us know if you get any news back from WD.
