dd-Befehl wird nach Ausführung langsamer

[fhihu]

Hallo miteinander,

ich habe ein paar gebrauchte Festplatte gekauft (in der Größe 4 TB) und wollte prüfen, ob alles in Ordnung ist bzw. die Festplatten anfänglich mal komplett löschen.

Ich habe dann versucht mit dd die Festplatte komplett zu überschreiben:

dd if=/dev/zero of=/dev/sdc bs=1M status=progress

Das läuft es immer bis ca 1,2 TB mit 167 MB/Sec. Das dürfte sicher in Ordnung sein. Aber ab diesem Zeitpunkt geht der Fortschrittsbalken nicht mehr weiter bzw. nur sehr sporadisch. Die Geschwindigkeit ist auch auf 37 MB/Sec gesunken.

Mir sind dann diese Fehler aufgefallen "199 UDMA_CRC_Error_Count 0x000a 199 199 000 Old_age Always - 7". Habe das im Internet recherchiert, das hat angeblich mit der Übertragung zu tun und nicht mit der Festplatte an sich.

Ich habe dann noch zwei kurze Tests gemacht, hier scheint auch alles in Ordnung zu sein. Ich habe dann versucht, noch einen langen Test zu machen, der wurde aber abgebrochen, da die Festplatte in PowerSave gegangen ist, obwohl der Test lief.

Kann das etwas mit dem dd-Befehl zu tun haben, dass der nicht mehr richtig vorwärtsgeht? Mir ist auch aufgefallen, dass die Festplatte ziemlich heiß war, vielleicht ist sie einfach überhitzt und deshalb ging nichts mehr vorwärts.

Vielen Dank für eure Hilfe

Das läuft es immer bis ca 1,2 TB mit 167 MB/Sec. Das dürfte sicher in Ordnung sein. Aber ab diesem Zeitpunkt geht der Fortschrittsbalken nicht mehr weiter bzw. nur sehr sporadisch. Die Geschwindigkeit ist auch auf 37 MB/Sec gesunken.

Das könnte damit zusammenhängen, dass der Schreibvorgang gepuffert erfolgt; d.h. am Anfang wird in den Puffer (Hauptspeicher) und parallel dazu auf die Festplatte geschrieben. Während die Platte noch mit dem Schreiben (des Inhalts eines Puffers) beschäftigt ist, werden die noch freien Puffer gefüllt. Oft ist es sogar so, dass auch die Festplatten eingebauten Pufferspeicher haben. Dadurch fällt es zunächst nicht auf, dass der eigentliche Schreibvorgang auf die Festplatte "viel" Zeit in Anspruch nimmt. Aber irgendwann sind eben alle Puffer (Betriebssystem und Festplatte) gefüllt und dann wird die tatsächliche "Schreibzeit" sichtbar.

Ist die Platte direkt mit einem SATA-Anschluss auf der Systemplatine verbunden oder verwendest Du einen SATA/USB-Konverter?

Hast Du schon einmal versucht, ob sich diese Art Fehler durch ein anderes SATA-Kabel und/oder einen anderer SATA-Anschluss auf der Systemplatine vermeiden lassen?

Hier noch der zweite Teil des Smart Berichts mit den Tests:

SMART Error Log Version: 1
...
The above only provides legacy SMART information - try 'smartctl -x' for more

Hast Du das mal ausprobiert? Bringt das andere Ergebnisse?

Wenn ich nach WRITE FPDMA QUEUED suche und Kabel und Anschlußbuche am mainboard als Fehlerursache ausgeschlossen werden können, hätte ich in die Platte nicht besonders viel Vertrauen.

Hat sich in der Zwischenzeit die Anzahl der Fehler erhöht?

Vielen Dank für eure Rückmeldungen.

Ich verwende ein USB-Gehäuse, um die Festplatte zu betreiben. Ich habe mir dieses dazu gekauft:
Gehäuse

Ich glaube, es ist ein Anwendungsfehler meinerseits
Ich habe die Festplatte überhitzen lassen. In diesem Gehäuse wird sie wohl zu warm, vor allem, wenn man versucht, 4 TB auf einmal zu schreiben. Für solche Anwendungsfälle ist das Gehäuse wohl nicht geeignet.
Sie hat eine Temperatur von 67 Grad erreicht, deswegen war sie auch nicht mehr handwarm.

Die anderen Platten hatten eine Maximaltemperatur von 46-48 Grad. Habe das mit dem Befehl smartctl -x herausgefunden.

Ich werde die anderen Platten nun nicht mehr mit dd quälen und kopiere auf diese betroffene Festplatte eher Sachen, die nicht so wichtig für mich sind.
