There were two related issues corrected by v2.0 of the software. They are:
1. "No space left on device" error.
2. The failure of AFP to properly connect, while other protocols work fine.
These issues were usually caused by the drive being powered off suddenly. However, to correct the issues, you MUST click the Reset button in the update tool after installing v2.0.
NOTE: Updating to 2.0 may destroy the data partition on the ED Mini. Please back up before updating.
NOTE: Selecting the Reset button will delete any created users and will reset the administration password back to ADMIN.
