S.m.a.r.t.?

Hi, one question for ya.
Does anybody know some link or anything like it or has the nerve to explain what are all those items that are checked in SMART? I tried googleing, but, i couldnt find detailed explanations...
Thanks!

 

S.M.A.R.T. - Self-Monitoring, Analysis, and Reporting Technology.
S.M.A.R.T. is a reliability prediction technology that anticipates the failure of a disk drive with sufficient notice to allow a user to back up data prior to a drive's failure. This technology is applied to both IDE and SCSI drives.
Drive architectures are not all the same, S.M.A.R.T. would therefore carries different set of attributes and theresholds for different drive model. Common attributes that degrade over time are identified as:
head flying height
seek error rate
re-allocated sector count
spin-up time
seek time
spin retry count
calibration retry count
data throughput

However, not all failures are predictable. For example, a power surge that damages hard disk electronics is an unpreditable failure. Mechanical failures are usually gradual and predictable, and account for 60 percent of drive failure.
The S.M.A.R.T. system technology of attributes and thresholds is similar in IDE and SCSI with only differences in their reporting manner.
With S.M.A.R.T, manageability and predictive failure capability can be provided through the Microsoft Windows Management Instrumentation (WMI) in Windows 2000, Windows XP, and Windows Server 2003.
Management applications can take advantage of these capabilities in several ways. Examples include taking an action based on seeing the "Failure Predict Event" launch or periodically polling the condition of "Read Failure Predict Status."

 

Yes, thanks for the time, i found that myself. The question was, what are those attributes representing?
What are RAW READ ERROR RATE, START/STOP COUNT, REALLOCATED SECTOR COUNT.... etc etc?
Explanation for those things i cannot find!

 

THANK YOU!!!!!!!
