Со вставленной флэшкой, все OK:

sda - SSD с системой, sdb - HDD c данными, sdc - флэшка.

Меняем флэшку на  внешний HDD - отображаются только sda и sdb.

Индикатор горит стабильно.
На компьютере (Windows 7), на ноутбуке (Ubuntu Desktop) все монтируется, читается, пишется без проблем.
Не USB сервера не хватает питания, чтобы раскрутить диск, я правильно понимаю?
