That error may be reported after a disk is reset during a FORMAT operation. Another related case is a media access after a MODE SELECT is used to change the sector size (e.g. from 512 to 528 bytes) and prior to a FORMAT command which actually reformats the disk to 528 byte sectors. So if a disk is reporting that ASC/ASCQ sequence for ever media access, then you need to format it. In that case sg_format in sg3_utils may be useful.
