Ahoj, včera na mě PC po start OS vykřikuje, že mi kolabuje SSD
SMART overall-health self-assessment test result: FAILED!
- NVM subsystem reliability has been degraded
SMART/Health Information (NVMe Log 0x02)
Critical Warning: 0x04
Tohle je proste varovani -
0x04 = NVM subsystem reliability has been degradedKonkretneji:
Bit 2: If set to ‘1’, then the NVM subsystem reliability has been degraded due to significant
media related errors or any internal error that degrades NVM subsystem reliability

Nema vubec smysl resit proc - tohle je ucelem SMART technologii - aby ti dali vedet vcas, ze ti disk odchazi a podle me to zafungovalo velice dobre. Dalsi krok je uz critical error 0x08 = read-only mode. A to uz typicky nedokaze nabootovat OS a budes muset hledat ctecku pripadne Live distro.
Takze bych to odzalohoval a disk vymenil. Pripadne to muzes reklamovat, pokud na to mas zaruku.. bohuzel u techto OEM disku pro brandove vyrobce neni nikdy jasna specifikace pro TBW, ale to v tomto pripade ani nepotrebujes prokazovat - proste disk rekl ze je vadnej, to se ti uzna rovnou.
Ad Percentage used, linkovany dokument na strane 122 zminuje:
Percentage Used: Contains a vendor specific estimate of the percentage of NVM subsystem life used based on the actual usage and the manufacturer’s prediction of NVM life. A value of 100 indicates that the estimated endurance of the NVM in the NVM subsystem has been consumed, but may not indicate an NVM subsystem failure. The value is allowed to exceed 100. Percentages greater than 254 shall be represented as 255. This value shall be updated once per power-on hour (when the controller is not in a sleep state).
Refer to the JEDEC JESD218A standard for SSD device life and endurance measurement techniques.
