Q2) I wish. Has the time come to acknowledge Microsoft's de facto definition of this op? Can we make x23 "obsolete" rather than "vendor-specific"?
Q3) Can we obsolete x8B? On the theory that for some people this will be the Seek op for 64-bit Lba's?
Thanks in advance. Pat LaVarre

Fun, thank you. I had heard rumour of devices moving out more than the 16 byte Cdb length limit of Atapi/Usb etc. and I had heard rumours of commands that move data both in & out, but this is very concrete.
