Most hard drives manufactured this year will be advanced format. It may still be several years before we get hard drives that don't lie. I haven't found any way to query the drive, other than looking up the model number on the manufacturer's website (which isn't always easy, and sometimes finds conflicting information because you get a "logical" size of 512 and a "physical" size of 4k). > Also, I posted a bug report for it here https://www.illumos.org/issues/2663 Thanks :-). We can now track the progress of the OI-specific discussion about this issue. _______________________________________________ OpenIndiana-discuss mailing list OpenIndiana-discuss@openindiana.org http://openindiana.org/mailman/listinfo/openindiana-discuss
