Hi Luis,

Error 5 is EIO or I/O err= or.  My first thought was if you are using USB 2.0 because those somet= imes have power problems (that would explain an I/O error).  Then I lo= oked at your log and it appears you are using 2.0. 

If I'm right, I suggest disconnecti= ng every USB device that you don't absolutely need and trying again.  = (The drive did pass a previous diagnostic test telling us that it was worki= ng.)  If that solves the problem, I suggest using a USB 3 drive or usi= ng a **powered** USB hub.

Hugh
