end_request i / o error, dev sdc sector xxxx - SSD Absturz?

Ich verwende Ubuntu 12.04 und es scheint, als ob meine SSD bei mir versagt. Nach einer beliebigen Zeit druckt die Disk nur end_request i/o error, dev sdc sector xxx wenn ich einen Befehl wie ls oder irgendetwas anderes eingebe. Dies kann nach 24 Stunden oder nur wenigen Minuten geschehen.

Alle SMART Tests (kurz/erweitert) bestehen und es gibt keine neu zugewiesenen Sektoren, obwohl ich nicht sicher bin, ob SSDs damit wie die älteren magnetischen Typen umgehen.

Die Anzahl der Programmfehler scheint das Hauptproblem im SMART log. 4745980543444) zu sein.

Was kann ich besonders anders als ein normales Festplattenlaufwerk?

Es scheint, dass dies eher eine grobe Firmware als etwas zu Ernstes ist. Sehen:

Hier ist der relevante Gumph:

Dieses Laufwerk kann nach 5184 Stunden Einschaltdauer hängen bleiben:
http://www.tomshardware.com/news/Crucial-m4-Firmware-BSOD,14544.html
Firmware-Updates finden Sie auf den folgenden Webseiten:
http://www.crucial.com/support/firmware.aspx
http://www.micron.com/products/solid-state-storage/client-ssd#software

Sie haben (vor kurzem) 5184 überschritten, damit dies umso relevanter aussieht.

In jedem Fall sollten Sie eine Sicherungskopie erstellen und sich darauf vorbereiten, dass die Sicherungskopie auf einer anderen Festplatte gespeichert wird.
