Dotaz: Nove SSD - Reallocated_Sector_Ct

[Michal Urban]

Zdravim,

chtel bych se zeptat, zda je je v poradku, ze nove (tyden stare) SSD (24GB Intel 313) ma nenulovou hodnotu Reallocated_Sector_Ct:

michal@SSD ~/.bin $ sudo smartctl -a /dev/sda | grep Reallocated_Sect
5 Reallocated_Sector_Ct   0x0032   100   100   000    Old_age   Always       -       10

Pustil jsem badblocks a podle toho je vse ok:

michal@SSD ~/.bin $ sudo badblocks -v /dev/sda
Ověřují se bloky 0 až 23452631
Hledají se špatné bloky (test jen pro čtení): hotovo                                               
Průchod dokončen, nalezeno 0 špatných bloků (0/0/0 chyb).

Zapomnel jsem to zkontrolovat, takze nevim, zda jsem uz na 10 zacinal ... cely vypis SMARTu je tady:

michal@SSD ~/.bin $ sudo smartctl -a /dev/sda

Podle mne to v pořádku je, jen bych hlídal, jestli nenarůstají, pak by to v pořádku nebylo.

[Michal Urban]

Ok, diky!

[Michal Urban]

Podle tohohle (http://serverfault.com/questions/282301/quick-method-to-determine-ssd-drive-health) a hodnot

232 Available_Reservd_Space 0x0033   100   100   010    Pre-fail  Always       -       0
233 Media_Wearout_Indicator 0x0032   100   100   000    Old_age   Always       -       0

By melo byt vse ok. Chapu to spravne?

[Pavel 'TIGER' Růžička]

Ano.
