Have for the hard disk a few weeks to work it verloren.Habe exchanged twice. Now, the third is broken. I have taken out the last plate from one computer and plugged into the other. Now showing on both computers the name is no longer on, the file system is no longer visible, and the capacity is 0. CHKDSK and Seatools found no errors. All plates me overthrew the Office programs for reading and writing from. Toshiba not get help.
