> e05104r0 Draft ERR/DRQ Technical Report > e05105r0 ERR/DRQ Technical Report Proposal Sigh... Why is this back? This is totally unneeded and confusing. This is simple... A device that has status of BSY=0 DRQ=1 and ERR=1 has violated the PIO Data In protocol (in ATA/ATAPI-7 see Figure 48 "Device PIO data-in state diagram) and/or has violated the PIO Data Out protocol state diagram (in ATA/ATAPI-7 see Figure 50 "Device PIO Data data-Out state diagram). I'm sorry if some device implementer designed a device that violates the PIO data transfer command protocol and rules, but that is no reason to add such a confusing SET FEATURES subcommand to the standard.
