Ich habe dieses Laufwerk mit einem Raspi verbunden, der plötzlich extrem langsam wurde. Auf einer anderen Website hat jemand empfohlen, zu laufen, smartctl -a /dev/sdcaber ich weiß nicht, was ich sehe und wie ich es reparieren kann (wenn überhaupt möglich).

$ sudo smartctl -a / dev / sdc

Viele " Read SMART Data fehlgeschlagen: Verbindungszeitüberschreitung " -Nachrichten werden angezeigt, was ungewöhnlich sein kann. Sieht nicht so aus -A, --attributes, als würden sie aus irgendeinem Grund gelesen.

Anstatt alle Zahlen selbst gsmartctrldurchzugehen, können Sie eine GUI wie eine "grafische Benutzeroberfläche für smartctl" ausprobieren. Es hat einige Funktionen wie:

  • meldet automatisch Anomalien und hebt sie hervor;
  • führt SMART-Selbsttests durch;
  • zeigt Laufwerksidentitätsinformationen, Fähigkeiten, Attribute, Gerätestatistiken usw. an;
  • kann die smartctl-Ausgabe aus einer gespeicherten Datei einlesen und sie als schreibgeschütztes virtuelles Gerät interpretieren;
  • verfügt über umfangreiche Hilfeinformationen.

Fenster mit Laufwerksinformationen - Eine fehlerhafte Laufwerksattributliste


Die Manpage von smartctl enthält einige Informationen zu den SMART-Attributen. Es scheint, als würden die Rohwerte nicht immer direkt mit dem Attribut übereinstimmen. Hier ist ein Auszug:

 Each Attribute has a "Raw" value, printed under the heading "RAW_VALUE", and a "Normalized" value printed under the heading "VALUE". [Note: smartctl prints these values in base-10.] In the example just given, the "Raw Value" for Attribute 12 would be the actual number of times that the disk has been power-cycled, for example 365 if the disk has been turned on once per day for exactly one year. Each vendor uses their own algorithm to convert this "Raw" value to a "Normalized" value in the range from 1 to 254. Please keep in mind that smartctl only reports the different Attribute types, values, and thresholds as read from the device. It does not carry out the conversion between "Raw" and "Normalized" values: this is done by the disk´s firmware.  The conversion from Raw value to a quantity with physical units is not specified by the SMART standard. In most cases, the values printed by smartctl are sensible. For example the temperature Attribute generally has its raw value equal to the temperature in Celsius. However in some cases vendors use unusual conventions. For example the Hitachi disk on my laptop reports its power-on hours in minutes, not hours. Some IBM disks track three temperatures rather than one, in their raw values. And so on. 

...

 Please note: the fact that an Attribute is of type 'Pre-fail' does not mean that your disk is about to fail! It only has this meaning if the Attribute´s cur‐ rent Normalized value is less than or equal to the threshold value. 

...

 If the Attribute´s current Normalized value is less than or equal to the threshold value, then the "WHEN_FAILED" column will display "FAILING_NOW". If not, but the worst recorded value is less than or equal to the threshold value, then this column will display "In_the_past". If the "WHEN_FAILED" column has no entry (indicated by a dash: ´-´) then this Attribute is OK now (not failing) and has also never failed in the past. 

...

 So to summarize: the Raw Attribute values are the ones that might have a real physical interpretation, such as "Temperature Celsius", "Hours", or "Start-Stop Cycles". Each manufacturer converts these, using their detailed knowledge of the disk´s operations and failure modes, to Normalized Attribute values in the range 1-254. The cur‐ rent and worst (lowest measured) of these Normalized Attribute val‐ ues are stored on the disk, along with a Threshold value that the manufacturer has determined will indicate that the disk is going to fail, or that it has exceeded its design age or aging limit. smartctl does not calculate any of the Attribute values, thresholds, or types, it merely reports them from the SMART data on the device.
