Т.е. все склоняются к мысли что это не проблема 4к.
Меня в выводе hdparm -i /dev/sdb не понятно почему
BuffSize=unknown
Т.е. нету буфера? Может ли это быть ошибка hdparm? Как-то можно это
проверить? Какие аргументы можно провести продавцу для замены?
При этом SMART девственно чистый. См вложение.
В dmesg из подозрительного только вот это
