.... I would like to set up either Crystal Disk Info or some other program to alert me if a HD is possibly going bad. I see Crystal Disk Info has a Startup check box and also alert by email. I prefer something working in the background instead of seeing a Window even if it's minimized. Of course is something is going wrong then a Window alert will be very welcome. So if anyone already knows how to do this, please let me know
Hard Disk Sentinel would fit the bill. It's often on free giveaway, see the discussions earlier in this thread, posts #25-#31.
