    PC Hard drive in a Laptop

    I'm going to be using a laptop in my mp3 system, but I need to upgrade the hard drive first. Regular PC hard drives are waaaaaay cheaper than Laptop HDs, so I was figuring I'd try to pick one of those up. However, there's the issue of the connector. I know there HAS to be an adaptor to allow me to use a regular Hard Drive in a Laptop, but I can't find one. Anyone?

    Thanks ..

    That is something I have never seen. A friend of mine built one from the opposite adapter that allows the 2.5" drive in a normal ide. They should be well under $10.

    Get 44 little pins and stick them in the adapter to convert the small female connector to a male and plug it into the laptop. Be certain the pins are long enough and the lengths are consistent. Then plug a normal ide cable into the other end and connect your drive to it.

    I don't know if he used the laptop power for the drive or a separate power source. If they are separate, make sure you can ground them together.

    Steal a male power connector off a dead cpu fan to get power from the adapter.

    You should be able to use a regular drive in a laptop with the 2.5 to 3.5 adapter. You will need to a gender changer on each port, and you will need to supply a source of external power.

    External USB Hard Drives, that is all I have to say.

    use your small hard drive to boot from, and use the USB to store your MP3's.

    See, the problem with using USB drives is that the cost is almost double a regular drive.

    $58 for a 30gig EIDE Drive
    $98 for a 30gig USB Drive
    $100 for a 30gig Laptop Drive

    Cost is the reasoning for wanting a PC Drive.

    Where can I tap power from a laptop to power an PC Drive if I create an adapter like previously mentioned in this thread? Are the extra 4 pins on a laptop drive FOR power? Could I use them somehow?

    I'm afraid a laptop HDD is going to be the most cost effective. Like Seanster said, unless you want a power supply dangling off of your setup, there's really no cheaper/better way. AFAIK, no laptop power supply can power a 3.5" HDD.

    My suggestion: Crowbar that ol' wallet open and buy a 2.5" drive.

    Laptop hdd's use +5vdc for both signaling an spinning the motor, where as desktop hdd's use +5vdc for signaling and +12vdc for the motor. As was eluded to before, there's probably not going to be a readily availible source of +12vdc to spin up your drive.
