hd Almost every EIDE or SATA hard disk includes S.M.A.R.T. data. That information is collected by the drive itself and contains data that the manufacturer considered relevant to check reliability. The data is made up of several attributes that have a current value, a worst one, a threshold, some raw data, and some flags. Basically, when any attribute's current value is below its threshold, the hard disk is considered unreliable and likely to fail. By using several techniques, this report tries to give a wider range of info, basing its analysis on advanced comparisons with normal values based on real hard disks and on expert-like checks. The final results are not to be taken as an absolute truth, but they are a very good approach to what a professional would say about your hard disk status.

NOTE: this is a sample result using default hard disk data. In order to get a real report about the health, status and reliability of your hard disk, please refer to SpeedFan.
Your hard disk is a Maxtor 6B160P0 with firmware BAH41B10.
The average temperature for this hard disk is 37C (MIN=27C MAX=48C) and yours is 34C.
Your hard disk's S.M.A.R.T. attributes are now being analyzed and a full report about the reliability, health and status of your hard disk is generated:
Your hard disk is not below any attribute threshold. This is good.
Your hard disk was never below any attribute threshold. This is good.
Your hard disk is now being compared to real data used to define normal values for your specific hard disk model. This way, the analysis can automatically use proper operating ranges. The images give you an idea of how each attribute is within such range. Current and raw values are shown for easier reference for experienced users. There are 3001 hard disk models in the current archive.
