siguardian™is a disk utility that checks and monitors the status of your hard drives to help prevent data loss. using s.m.a.r.t. technology included in all modern hard disks, this program analyzes and calculates the date your hard disk will reach its threshold exceeded condition (t.e.c.), when keeping data on it will no longer be safe, so that you can pro-actively back up all of the data on that disk. checking the disks at system startup so it doesn't use memory while you work, this program shows all s.m.a.r.t. statistics both graphically and numerically, including raw attribute values, worst attribute values, and threshold values of attributes. residing in the system tray, this utility can be quickly brought to life in order to run a t.e.c. simulation on a selected hard drive. self monitoring analysis and reporting technology (or s.m.a.r.t.) is a technology that enables a pc to in some cases predict the future failure of storage devices (like hard disk drives). pioneered by compaq, s.m.a.r.t. is under continued development by the top five disc drive manufacturers in the world: seagate technology inc., ibm, conner peripherals inc., western digital corporation, and quantum corporation. armed with prediction information the user or system manager in some instances has the opportunity to backup key data or replace a suspect device prior to data loss or undesired downtime.
