Strictly speaking, this is a Banana Pi question. However, one might want to do something similar with a Raspberry Pi, so I consider it appropriate to ask here. Hope I'm right.
Now the Banana Pi has an eSata connector. I can hook this up to a hard disk drive, and what I've got is an internal 3.5" HDD. I would like to keep this configuration as a home server, however, I am afraid that the HDD will not like this mode of operation - lying around loosely while spinning. What is my best option to keep the HDD safe and working? Do I need a case?
