I would like to see this clarified as well. I ran into this problem a number of months ago and reported it here, but it was never resolved. I saw this problem on drives from two different vendors, and didn't think to look elsewhere in the spec to find that bits 5 and 7 were obsolete. At least now I understand why, but it should be clarified in the spec.

Good morning, After speaking with Dan Colegrove yesterday, we agreed that I would post a request for a clarification (in the spec) as to exactly what the ATA reset signature should be. This stems from the spec indicating the signature should be 1,1,0,0,0. However, in other locations in the spec the dev/head register is marked as having bits 5 and 7 as obsolete. The inference there is to ignore those bits - and, as Dan pointed out, even in the signature. We had assumed otherwise and were failing to recognize a 2.5 inch drive that reported 1,1,0,0,A0 as its signature - which I am told is acceptable. So, I'm wondering if others are confused by this as well, and if it would be possible to get the spec to clarify this (and, while that's in progress, if I could get a note from the committee for my boss <g>) Thanks! josef Zeevi
