Vreemde meldingen in "dmesg" bij gebruik USB-HDD

[Josefien]

Mijn vraag
...
Het valt me op dat als ik op mijn Linux-server een USB-HDD hebt gebruikt om een back-up te maken, ik naderhand een aantal van deze meldingen in "dmesg" zie:

[5701194.595997] sd 7:0:0:0: [sde] Unhandled sense code

Het maken van een back-up is simpelweg de USB-HDD aansluiten, koppelen met "mount", een back-up maken via "rsync", een "umount" doen en dan koppel ik 'm weer af. Tijdens welke stap deze meldingen komen, weet ik niet precies. Maar "rsync" geeft geen foutmeldingen.

Een uitgebreider stuk uit "dmesg":

Wat betekenen deze meldingen? Kan het kwaad? Het zijn geen bad sectors en de back-up blijkt bij een steekproef ook gewoon leesbaar.


Relevante software en hardware die ik gebruik
...
- Debian 8.0 (OS)
- WD Elements 640GB USB2.0 externe HDD


Wat ik al gevonden of geprobeerd heb
...
De externe HDD aansluiten op een andere PC. Daar overleeft hij een fsck zonder problemen. Op de server trouwens ook.

Waarschijnlijk ondersteunt je harde schijf (of de usb-chip er tussen) niet alle commando's.
Zie bv

[Verwijderd]

Kan een quirk zijn van de controller (in de USB-behuizing) en niet van de schijf zelf. Het kan ook simpelweg gaan om instructies die niet worden ondersteund zoals thunder7 aanvoert. Hoe dan ook, in de meeste gevallen kun je dit negeren, mits de meldingen zich consequent voordoen en dat patroon ook niet wijzigt.

[Josefien]

Het is inderdaad zeer waarschijnlijk de controller in de behuizing​ die bepaalde zaken niet ondersteunt. Vandaag had ik namelijk backups gemaakt op een andere schijf met dezelfde type behuizing en ik krijg dezelfde meldingen.

Het is er wel pas gekomen na de upgrade naar Debian 8.0. Daarvoor draaide het op 6.0 die deze meldingen niet gaf.

[Rik.]

Als het pas is gekomen na de upgrade lijkt het erop dat er commands uitgevoerd worden in debian 8 die in debian 6 niet uitgevoerd werden en niet worden ondersteund door de controller.
