I can see from scsi.h that 0x85 is the code for ATA_16, but > I'm not sure what that command actually does. I have never heard of any kernel driver issuing either the BLANK command or an ATA_16 pass-through command. It almost certainly is a user program doing this, but I don't know which one. Booting into a minimal userspace environment (for example, with init=/bin/bash) might prove this. No doubt the reason the drive fails to respond is because it can't handle these commands and gets fatally confused.
