I have a 37PFL9606h/12, and have bought a brand new western digital extern harddrive 1tb ( http://wdc.com/en/products/products.aspx?id=640 ).
I have succesfull connected the drive to the tv , and I can explore it.
However to make use of it it needs to be formatted. Formatting goes on but at the end I get an error that formatting cannot be completed due to too low writingspeed. That is an odd problem for a new hard disk!

Does anybody have an idea what is going on or what can fix my problem?
