I got a WD hard disk about 2 TB. works perfectly except if the power goes out as did 1 hour ago, it won't read the HD. I can still access files but it wont reset seeding and it has a message.
Error: former volume not mounted. I can highlight each and restart, then it resumes seeding and downloading.

Normally I wait till marmite come around and he gets it right. But I think Marms tolerance for the elderly is wearing a bit thin.
I thought a Remote PS might help, it didnt.
