When I boot my system up, and it auto detects the drives, next to my hard drives, it says "S.M.A.R.T for hard disks disabled." I didn't know what is was, and so I enabled it. This caused big problems, giving me a lot of blue screen crashes, so I disabled it and I have had no problems since. What is this feature and what does it do, and what did it keep causing blue screen crashes? Jim.

Acronym for Self-Monitoring, Analysis and Reporting Technology, an open standard for developing disk drives and software systems that automatically monitor a disk drive's health and report potential problems. Ideally, this should allow you to take proactive actions to prevent impending disk crashes SMART should only be enabled on hard disks with SMART. If you enable it on a hard disk without you get lots of problems like you have.

Thank you for your response. I think the hard disks are SMART capable, when I boot up, next to each hard disk, it says "SMART capable but disabled" I don't know why the systems crashes even though they are capable... I don't need it though the machine seems to be running fine without. Thanks anyway

Probably the disks are NOT, but what you see is that the BIOS is capable buy disabled.

The only thing SMART technology does is monitor the HDD and give you a warning if it detects drops in RPMs or other indications that the drive is about to fail. Your drives will function just fine without it.

Thank-you both DDS and ranchhand, that has cleared some things up, I'll just keep it disabled and the drives are functioning fine... Thanks again, Jim.
