Thank You.
Okay, so this would be considered a bug in the device or is this acceptable
for a device to do?
I'm looking for some reliably way to know if to send Read16/Write16 and need
to know at the time the device is checked out (including device that may not
have media inserted - which mean read capacity won't work because many
devices fail with no media inserted).
I didn't find any general mandatory command to check if a command is
supported except for 0xA3, but that always failed check for READ16 / WRITE16
even on devices that supported it (unless I did something wrong):
  BYTE paramdata[4];
  memset(paramdata, 0, sizeof(paramdata));
  BYTE cdb[12];
  memset(cdb, 0, sizeof(cdb));
  cdb[0]=SCSIcmdMaintIn; // 0xA3
  cdb[1]=0xC; // service action
  cdb[2]=1;   // report type
  BOOL result;
  if ((result=SendCommand(.) ))!=FALSE) {
    // check if supported
    if ((paramdata[1]&0x7)<3) {
  // return to caller
  if (cdbsize) {
  return result;

No, RBC has not been changed, there is currently no RBC-2 project, and there
are currently no plans for one in the future.

Has the RBC command set been changed to support Read16 / Write16 ?   If so,
what version?
I've got a 6TiGB device connected via 1394 reporting that it uses the RBC
command set.
