  • cdr/dvd drive

    i bought a cdrw.dvd rom external drive for my carpc and i have a 160w power supply. the carpc has a cd rom already installed but when i try to hook up the drive it wont read the disks nor will the pc show its hooked up to it via usb

    Did you supply the external drive with power too? Usually it needs additional power and only uses the USB for data transmission.

        Usually 5v for a slim drive.

        You can pull the 5v from the red wire on a HDD molex conenctor.
        Have you looked in the FAQ yet?
        How about the Wiki?

            and use the barrel connector/wire off the AC power supply that came with it. You will have to use a multimeter to figure out which wire is 5V and which is GND. Otherwise, go to radioshack and pick up the power conecter that plugs into the back of the drive and wire it up correctly. If you wire it backwards you will kill the external drive. The extrenal drive will inidcate polarity of how the plug should be.

              Not if you want to retain a functioning optical drive!
              The car's electrical system (including the cigarette lighter) are 12v. A slim drive usually requires 5v. The fact that your power connector has a USB connection, it confirms that your drive requires 5v.

              Again, tap into the 5v on a HDD molex connection for power. The red wire is 5v. The yellow wire is 12v.

                yes I think I have seen a convertor like that. It has to convert the 12v to 5V.

                  search for cigarette lighter to usb

                  correction: Not enough current to power it properly. YOu need soemthing to do 2A or more probably. this will only do 0.7A after seeign the pic up close. Just wire it from the molex connector and hack the usb cable power cord unless you drive only needs 700ma to power it.

                      look here at the disk drive connector from your computer PSU:

                      http://en.wikipedia.org/wiki/Molex_connector

                      http://en.wikipedia.org/wiki/Usb

                      then take your usb power cable and cut it. Figure out what wire is connected to the outer ring on the barrel connector using a multimeter set to ohms. that will be ground ususally. the inner pin shoudl be 5V.


                      Added:
                      Use wire from PIN 1 USB to RED wire on Molex
                      USe wire from PIN 4 USB to Black wire on molex
