The only way I know of to re-set the drive to original settings would be to restore the original firmware that it came with.
Problems with that:
1. Older firmware will mean less support of current media, for instance latest write speeds and newest media types won't be recognised.
2. Older firmware will also mean that later fixes released by the manufacturer will not be captured. You could in fact cause yourself more problems.
Almost without exception you want the latest firmware (save for ones with known bugs) on your drive. Therefore if you have tried what the boss suggested in his post at the top of this page and that made no difference you should consider a new drive. If it's an internal one they really are cheap as chips nowadays
