Then flip the logic (10 then 6). These devices are supposed to report that the command is not supported. All indications I have is that the newer drives do. Older drives just fall of the bus and die if you send a 10byte cdb. >Anyway the *(10) commands are NOT functionnally equivalent to *(10) >function as you know. Right. Look at the code that builds these commands. The smallest command type that can satisfy a given request is used. You can optionally set a minimum command type size too. >May-be you just want to have best possible support for hard disks < 1GB. They work fine now.
