We're currently trying to find out what's actually going on with all these drives. At first, drives which got blacklisted aren't many and made sense (had other problems with NCQ, etc..) but with new generation drives from many vendors showing the same symptom, we aren't too sure now.Is there a way to tell whether Windows is using NCQ or not? I checked the system log (or whatever it's called) on my notebook and is clean but I'm not sure it's using NCQ (I don't even know if it'd log spurious completions somewhere).
Which driver is installed for the SATA controller in Windows, the chipset-manufacturer-provided AHCI driver or the default Microsoft driver? You'd need the AHCI driver installed for NCQ to be used.
