[Linux-Biella] Disco che va? o USB Controller?

[Daniele Segato]

Un disco usb ultimamente mi dava noie
lo trovavo scollegato
con errori nei log...
spegnevo e riaccendevo e andava...

preso disco nuovo

dopo pochi giorni ha preso a far la stessa cosa..

sfiga? (ovvero è il disco) oppure ho un problema all'USB controller?
