Zdravím!

Delší dobu mám rozdělaný počítač a nebyl čas, abych ho dodělal (bastlím 19" case do racku). Takže teď tady ležel cca. půl roku bez proudu. Chtěl jsem do něj teď přidat další disky, ale po nastartování hlásil spoustu chyb čtení.

Pokud ovšem na SSD zapisuji (reálnými soubory), pak vše bezproblému přečte. Taky jsem přepsal partišnu, které zabírá 100 ze 120 GB na SSD nulami a i když se předtím na ní vyskytovaly chyby, teď ji přečte bez problému.

Smartctl hlásí tohle:

Otázky:

1. Je pravděpodobnou příčinou to, že SSD stálo bez proudu, nebo je to něco jiného (mohl tam být ještě nějaký krátkodobý problém s napájením - špičky, či tak něco). Je první varianta běžná/pravděpodobná?
2. Pokud bych SSD dále použil, pomůže předejít podobnému výpadku, pokud bude neustále napájeno (má se jednat o server/NAS)?
3. Doporučili byste SSD dále použít, nebo raději nahradit novým?
