Thanks jaclaz for your reply. I am a bit confused. 1. I decided to buy (not cheaply) Nokia cable CA 42 after having see the informative video by nitrohelix (Thanks for that!), and because my laptop does not have Serial ports. 2. Now I read around (from two or three members) that there may be issues: 2.1 In case the cable is not Original -- this is not my case 2.2 In the case the cable si Original, but looks like the following (picture borrowed from Jhothagondyaz in his post here June 26:thanks) -- this is also my case 2.3 In case of using a laptop -- this is my case too. I did not try the HD connection (just yet), because I would like to test that the Cable works in first instance, being the one with trouble 2.2. I learned that a loopback test is what I need. As I said however I do not have any recognition that the cable after installing Nokia Setup.msi as described in the previous post of mine. [[EDIT: Now I attached a battery of 3v to cable 1 and 5 and CA 42 is perfectly recognized by the laptop. Windows Devices shows an additional Modem as Nokia CA 42 USB Modem. I set up the hyperterminal connecting to the port (COM4) of the Nokia modem, I had first the impression that the loopback did not worked (I used also TeraTerm 3.13), because I did not see my typing retyped back. However I later understood that the loopback is just this: see what you typed on the keyboard. /End EDIT]] I did not understand if Jhothagondyaz was able to come out with a final solution, since he was with the same cable of mine (I send him a PM to ask this - no answer yet). My questions are: 1) Is it a problem of power supply to the cable? 1.1) Do I need to use 3V batteries to pin 1 and 5 (Nokia mobile side of the cable), to make CA 42 detected? [[EDIT: To these two questions the answer is YES if you have Cable 2.2 /End EDIT]] 2) After Cable detection, and with the presence of Nokia CA 42 USB Modem, how will be the settings for the hyperterminal (or TeraTerm 3.13 portable edition)? [[EDIT: Just be sure to pick up the same port of Nokia USB Modem. The loopback does not mean that you see what you typed twice. You will see it just once /End EDIT]] 3) I guess that the batteries should stay there during the connection to the Seagate. Is this correct? If this is so do I need also to attach the GND (black cable) in addition to Rx and Tx, being the power of the CA 42 different from the power of the HD? [[EDIT: I tried and both questions do have a YES answer /End EDIT]] TIA for any help. [[EDIT: I hope the EDIT notes may be to some help to other members /End EDIT]]
