CrystalDiskInfo is a HDD/SSD utility which supports S.M.A.R.T.
CrystalDiskInfo is a tool that can display technical information about your hard drives including but not limited to firmware, serial number, type of interface, how many times the hard drive has been started, how many hours has been on, Etc. This portable app also has the ability to tell you the status of your hard disks by a using a simple status message (it can be good, caution, bad or unknown) and the current temperature, it also displays S.M.A.R.T. statistics that can help you diagnostic a hard drive more accurately tough i wouldn't bother with this feature unless you can make sense of the very technical numbers that you are given. The last noteworthy feature i would like to mention is the controlling of certain special features that hard drives have, for example with CrystalDiskInfo you can manage the AAM and APM features of your disk, handy if you want to make your hard drives quiter or manage your power settings.
In conclusion i feel that CrystalDiskInfo is a pretty good program for knowing your hard disk info and optionally to do some very technical stuff, its' worth checking out. Available for Windows 2000/2003/XP/Vista.
