how do you keep a hard drive from powering down? Answered

When i opened a hard drive and powered it  with +12 and +5 volts the platter spun, but the hard drive powers down after about 40 seconds. I'm guessing its because it's idling, but how do a force it to keep going without programming a arduino to send signals through the ide?

Is it a newer hard drive?  Many new drives will automatically spin down if they detect no activity from the computer.  In your case, there is no computer!

There is probably a hack to keep it running, but I'll defer that answer to someone in the know...
