Unmap worked fine, though. So Bernd> possibly there is another blacklisting required. Well, the 510 is a SATA drive and doesn't implement either command so that would be an LSI SATL problem. I recall that we had some problems with the LSI firmware blacklisting DRAT/RZAT on that particular drive so I did the same in my libata patch. I don't have any bugs open with WRITE SAME or UNMAP on recent LSI firmware, though. We use it extensively here. -- Martin K.
