    What does it take to spin up an IDE hard drive?

    Here's the scenario...
    You're at a swapmeet or garage sale or picking up
    a drive you bought on Craigslist.

    Me: "Is it free of bearing noise?"
    Seller: "Oh yeah, was my brother's primary drive."
    Note, the question was completely avoided...

    And you get it home and it sounds like an airplane taking off.

    If you plug in power, most IDE drives won't spin up.
    Taking along a power supply is easy. Booting a laptop
    and using a USB/IDE converter...not so much.

    Is there a simple way to make an IDE drive spin up when powered?
    Connector with some address/select pins wired to ground???

    Thanks, mike

    That's not my experience; old IDE drives and new SATA drives
    power up and start spinning when raw power is applied.

    SCSI drives, on the other hand, were made with various
    options (because a simultaneous startup of an 8-disk
    RAID was likelier to pop fuses than to perform
    normally). Many-parallel-disks operation of IDE was
    relatively uncommon.
  3. Nothing that beats one of the IDE/SATA -> USB adapters. Then you can test
    the drive straight away too.
