smart: насколько страшно?

Hetzner. Взял несколько серверов на один проектик. Больше половины винтов в смарте показывают такое:

SMART Error Log Version: 1

ATA Error Count: 5

CR = Command Register [HEX]

FR = Features Register [HEX]

SC = Sector Count Register [HEX]

SN = Sector Number Register [HEX]

CL = Cylinder Low Register [HEX]

CH = Cylinder High Register [HEX]

DH = Device/Head Register [HEX]

DC = Device Command Register [HEX]

ER = Error register [HEX]

ST = Status register [HEX]

Powered_Up_Time is measured from power on, and printed as

DDd+hh:mm:SS.sss where DD=days, hh=hours, mm=minutes,

SS=sec, and sss=millisec. It "wraps" after 49.710 days.

Error 5 occurred at disk power-on lifetime: 23055 hours (960 days + 15 hours)

When the command that caused the error occurred, the device was active or idle.

After command completion occurred, registers were:

ER ST SC SN CL CH DH

-- -- -- -- -- -- --

40 51 00 02 06 3e 00

Commands leading to the command that caused the error were:

Сейчас ошибок нет, все делает вид что работает стабильно. Вопрос - насколько это критично и можно ли оставить так? Или пинать их до тех пор, пока не заменят все винты на диски с чистой историей?

PS Я понимаю что хетцнер - дешевка на десктопах.
