Hallo zusammen,
Welch Ursache kann es haben dass eine Festplatte plötzlich den Status Degraded zeigt?
Platte im A..... möglicherweise.
Besteht dabei die Gefahr dass die Daten verloren gehen?
Ja. Drum Backups bereithalten. Das sollte zwar ohne Verlust machbar sein. Aber murphys law sieht das nunmal anders.

Was sagen denn die smart Werte?
3ware sollte ja, je nach Controller, mit smartmontools laufen. http://sourceforge.net/apps/trac/smartmontools/wiki/Supported_RAID-Controllers
