Dotaz: Logování SMART událostí v disku.

[lertimir]

Pokouším se přesvědčit moje SSD, aby logovalo události. Hlavně krátké a dlouhé testy. Podle smartctl -a /dev/sda by mělo mít Error logging supported. v jedné části a v druhé má napsáno Not supported

hledám jestli se nějakým flagem smartctl logování nezapne, ale zatím to mi nejde. Jde to nějak nahodit? připadá mi divné, když by nešlo.

Obycejne consumer SSD podstradaji firmeare podporu pokrocileho self-logovani a reportu.

- Kingston KC100 vs HyperX - Micron C400 vs Crucial M4 - OCZ Deneva vs Agility apod.

Tak to mne tedy nepotěšilo
