I have tried to connect the DVR to my new home recently but It was giving me error No HDD to write. Previously It was working fine for almost 2 year in my old home. I have removed the HDD from DVR and place it as secondary slave in my home desktop. I can see the same in BIOS setup but can't see drive letter (D or E) in my computer. Is the HDD faulty? or may be anything else. Pls advice. Regards
