I brought up on the reflector awhile back about adding a bit to IDENT to indicate SATA device. I remember mentioning it would be a good thing especially since not too many SATA devices were out in the field at that time. As more and more are shipped and more and more incompatibilities are found is anyone considering this yet. I know it would mean that a SATA paddle card would have to capture IDENT command and modify the data and this might not be an ideal thing to do. But what about the native SATA devices? I didn't see any mention of it in the minutes from Oct. 2003 meetings. I have also gone through the latest ATAPI-7 Book 1 and see no mention of it. Is there a reason no one wants to do this. It just seems like everyone would like to know if the attached device is really a SATA device or not and there seems to be an indication that it is needed more and more.
