With three known exceptions - fake ones generated by some IT821X adapters in RAID mode - certain old Maxtor PATA drives had a peculiar firmware failure where they changed to some kind of default serial number. Very unusual. Was never really fully explained and seems to have been very rare. - drives so ancient they don't support IDENTIFY, and we don't support them in libata anyway !
