Hello Isramozart, have you tried connecting the My Book to another PC or using another USB cable?

Shure! Not just change usb cable to another one, but trying firewire port too.
Also connected to iMac to see if disk recognized (even NTFS is not Mac file system).
Besides, I completely disassembled the box, pulled disks out and checked them individually using external sata to usb unit.
What else?
I tried to resset settings inside the disc using the button on the rear panel.
