How do you fix a computer where the hard-drive is only recognized when it has already spun up?

In all other aspects, the hard-drive works perfectly (with a S.M.A.R.T test showing no errors). What could be the cause of this, and is there any way to fix it?

If you can access the BIOS on your computer, then I would look for that option and see if you can extend the delay.

If this is a recent occurrence, then it could be a sign that the hard-drive motor is beginning to fail and can no longer spin up as quickly as it used to. This would be a bad indication as it may not be able to spin up at all soon.
