Format Error occurred at offset

[dantopa]

Hi, I'm having lot of troubles with my Toshiba Canvio external hd 2tb. Disk access had become really slow, so I made quick wipes a few times, but problem is still present. Finally I decided to make a low level format with hdd low level format tool. The software is still formating, but there is a "Format Error ocurred at offset...: 23", and a lot of "Format Error ocurred at offset...: 1". What does those numbers means? Are the disk recoverable? Is the disk death?

Thanks
