Hallo,


Ich bräuchte einen Rat bezüglich einer SSD welche ich in Zukunft eigentlich als Backup Medium verwenden wollte. Diese SSD hing bei mir in einem Synology NAS soll nun in Zukunft an meinem M1Mini als Time Machine Verwendung finden.
„Smartctl“ lieferte folgende Meldungen, welche mir aber nicht direkt etwas sagen und ich weiss nicht ob ich Platte nicht lieber "entsorgen" soll. Die verschiedenen Fehlermeldungen verunsichern mich nun.
Danke im voraus

Ich sehe da jetzt nix, was einer weiteren Verwendung entgegen stehen würde.
 
Danke - ja einerseits sagt der test "SMART overall-health self-assessment test result: PASSED" aber weiter unten gab es dann doch einige Fehler - zu diesen finde ich aber nichts. Sind das schon defekte Blöcke/Zellen?
 
Hi

ich bin mir nicht sicher, aber die meisten Programme für die SMART-Parameter sind doch noch für HDD ausgelegt und für SSD werden einige Parameter falsch ausgelegt

Gruß yew
