2783/24=115 so lange hab ich das Gerät doch noch gar nicht. Ist wohl doch nicht nagelneu. Nein, das sind Minuten. pffft gut gegangen.

Ich werde die Abschaffung unseres Kühlschrankes beantragen ;-)
Implicit wird es wohl drin stehen. In "man smartd" kannst du mal nach "HOUR" suchen. Da findest du eine Bespielkonfiguration, wo die 9 mit Power_On bezeichnet wird. In dem Manual zu smartctl wird die Option -v beschrieben
Gut, danke.

The power-on timer (Attribute 9 raw value) on my Maxtor disk acts strange.
There are three related problems with Maxtor's SMART firmware:
1 - On some disks from 2001/2002, the raw value of Attribute 9 (Power On Time) is supposed to be minutes. But it advances at an unpredictable rate, always more slowly than one count per minute. One (unconfirmed) theory is that when the disk is in idle mode, the counter stops advancing. This is only supposed to happen in standby mode.
Die sollte jünger sein. Na ja ich werd das prüfen.
2 - In Maxtor disks that use the raw value of Attribute 9 as a minutes counter, only two bytes (of the six available) are used to store the raw value. So it resets to zero once every 65536=2^16 minutes, or about once every 1092 hours. This is fixed in all Maxtor disks manufactured after July 2003, where the raw value was extended to four bytes.
Nochmal aus obigem Output: Note: timestamp "wraps" after 2^32 msec = 49.710 days.
OK, danke an Euch beide. Ich werde jetzt erstmal ein Konfig-File zusammenbauen damit mir die Uptime nicht ewig um due Ohren gehauen wird.
