Hi. My long-owned SH-223 (DVD/CDROM) shows up in Device Manager. It is not playing but that is the subject of another thread. I've just recently bought two more (cheap to buy,) but neither show up in Device manager when I connect via a USB cable I have. My USB cable fits onto the whole length of the socket at the back of the drive. It seems strange that both recently bought drives don't show up in Device Manager. I post this to be sure my two recent drives are bad. If so it's just complete coincidence that both recently bought drives are bad. Thanks. Rich EDIT: I am assuming both newly bought drives are faulty unless someone can suggest or show that assumption is an error.
