I'm using the A20-OLINUXINO-MICRO with a small SATA drive. When I plug in the cables and boot the A20 it comes up fine, but the disk doesnt auto-mount. Also I notice the drive makes a constant clicking sound, about once a second.
It's a new disk - so not expecting any issues at this stage.
Probably not providing the right power to the drive or a cable problem.
Don't rely on a new drive being OK - test it.

Thanks - I was trying to power it from the A20 board with the power adapter. Using an external PSU worked fine.
