Im having issues with keeping an external USB hard disk mounted.
Got my pi, started playing and decided to go out and buy a 3TB external HD to connect to my pi. The hard drive is self powered and I'm connecting that to a powered USB hub and then into one of the pi's USB ports.
Using the pi, I created a new partition and reformatted the drive using mkfs.ext3.
The drive mounts (takes FOREVER) and I can read/write files to the drive. But after some inactivity, I come back to the pi and get I/O errors when I try to access the drive. I then need to umount and re-mount the drive.
What could be causing this disconnect? I'm trying to rule out power because the drive is self powered by it's own PSU and it's also being connected to a 2.0 A usb hub before the pi. The pi itself has its own 1.0 A power supply (phone charger).
Anyone have any ideas?
