But when I initialize the hdd then it give me access but when I safely remove the disk & in the next moment I try to connect to my computer it does the same thing. After several time I format the NW-HD5 from windows after it show error 022 then I close the player but after that when I try to open the player it show the round moving logo for a min. & turn the system off. And it also doesn’t connect with the computer. i bye this 2nd hand so I don't have the warranty paper or purchase doc. so I can't even send to the dealer. Please help me. It is one of my favorite things. Thanks in advance Sorry for my bad English.
