Hello,

I try to:

Format via WD_Quick_Formatter_Win_1_2_0_10 don’t work

Install all drivers find for MyPassport don’t work

Format via md-dos don’t work

Format via windows format (in this step, i see HD are 976GB/976GB) don’t work

I try to change driver letter, in this step simply stay in connecting to virtual disk service…

I saw some answers saying to put more “energy in it” might work, i have a ipod touch adapter for recharge, can i try this?

I have this HD 6~7months.
