Normally, it's not a smart decision to enable the S.M.A.R.T feature in BIOS settings. The reason is that this may slightly affect the operation and may decrease the hard disk performance. For a better experience using the disk and optimizing the drive performance, it's highly recommended that you turn to a hard drive S.M.A.R.T monitor software or tool as recommended on this page for help. It's easy and efficient, causing no damage to your disk at all.
