Not recognising USB 3.0 hard drive Tags: Hard Drives NAS / RAID USB3 Storage Last response: January 20, 2013 12:38 PM in Storage Share Antares88 January 20, 2013 11:13:45 AM Hi. I just set up the Icybox NAS enclosure through the web NAS interface. NAS works fine. But when I switch the USB 3.0 cable with Ethernet my MacBook Pro 2012 won't recognise this external hard drive. Disk was formatted in exFAT format. Any ideas on this issue? Regards, Nino!

Antares88 January 20, 2013 12:23:18 PM There is no switch for host/slave mode. I tried the exetrnal disk connecting on an WinXP laptop and it recognised it. Can't find your answer ? Ask !

There has to be something wrong with my MacBook Pro USB 3.0 connection? So far, other USB devices worked fine, but they were all USB 2.0. Can't find your answer ? Ask !
