    I'm trying to use the -trim-sector-ranges flag to reset my SSD but I have to keep trimming in 65535 increments. Why can't I just run "hdparm -trim-sector-ranges 0:62533296 /dev/sda" The help info for that flag is very vague and the error isn't very descriptive in telling me what's wrong.

    Use -security-erase to trim an entire SSD.  Much simpler.

    But yes, it would be very good if hdparm could break up requests into smaller ranges automatically.
    It doesn't today, though.  Got a patch?
