| May 23, 2015 at 15:37 | comment | added | scruss | Just tried this with a Raspberry Pi 2 and a very similar My Passport Ultra 1TB. Plugging the drive into the hub worked no trouble (dmesg shows the all-important "… mounted filesystem with ordered data mode" after the SCSI lines). Plugging the drive directly into the Raspberry Pi 2 spun it up, but it kept trying to remount and locked the system 9. So it's likely a power thing. Use the hub for the drive connection and tell us how you get on. | |

| May 23, 2015 at 12:47 | comment | added | Phil B. | 1) is the powered hub strong enough? I have some 4 port hubs that claim to be powered but really just provide the minimum 500mA to each port, and most external USB HDDs need a bit more than that. | |
