Как узнать данные S.M.A.R.T.
S.M.A.R.T . - это губо говоря доступ к диагностической информации винчестера: времени работы, ошибкам и прочему.
Установим пакет smartmontools
sudo apt install smartmontools
Узнаем, какие диски есть в системе:
xxx@xxx:~$ sudo smartctl --scan
/dev/sda -d scsi # /dev/sda, SCSI device
/dev/sdb -d scsi # /dev/sdb, SCSI device
/dev/sdc -d sat # /dev/sdc [SAT], ATA device
Т.е. видны три устройства sda, sdb, sdc
Посмотрим S.M.A.R.T. для sdb:
xxx@xxx:~$ sudo smartctl -a /dev/sdb
Выводится зачастую большая портянка инфы, но в ней нас больше интересует табличка
