Ho un disco vecchio di un anno che mi sta dando problemi. La copia dei dati non riesce dopo circa 8-10 GB di trasferimenti. Si trasforma spontaneamente in "sola lettura". Ext4 è formattato correttamente, sono il proprietario. Cercando online, sembra che questo sia un sintomo di un disco guasto.
Come posso confermare ciò, poiché i test SMART indicano diversamente?
Ho fatto l'ovvio come controllare l'Utility Disco ed ho eseguito il test SMART esteso. Tutti i risultati di Utility Disco tornano perfetti. Tasso di errore di lettura e settori riallocati mostrano zero.
Immagino che questo disco sia danneggiato e SMART non lo rilevi, anche se non capisco perché. Vorrei confermare qual è il problema.
Non ho problemi con gli altri dischi nella macchina.

Ultimo ma non meno importante è lo screengrab di lettura / scrittura, questo è nuovo. Rimase piuttosto coerente per tutta la durata del test.
EDIT- Quando ho acceso questa mattina l'unità era cambiata da / dev / sda a / dev / sdc, strano. Sono certo che non è mai successo prima e sono certo che fosse / dev / sda. Ho scambiato i cavi SATA con uno noto e ho visto lo stesso errore a trasferimenti di circa 10 GB. Non ho ancora cambiato le porte SATA, lo proverò dopo. (Modifica n. 2, era la porta SATA, cambiandola risolto il problema. Contrassegnandola come troppo localizzata.)
