SMART Threshold and Attribute Viewer

Top  Previous  Next

Threshold and attributes are only applicable for IDE disk drives (which includes SATA disks).

SCSI and Fibre Channel drives provide additional statistical information which may be viewed by examining the log pages.

 

With version 1.28, we added additional information to the -S output. Previously we would report something like:

First and foremost, the above information should not be used to estimate remaining life in a device. The attributes and thresholds are all vendor/drive specific, and only the manufacturer has the technical expertise to interpret this information. It is our desire to make it available to you, so you may discuss this information with your supplier in event of a drive problem.

 

In the event of a S.M.A.R.T. alert, you should immediately back up your data. After that, contact your vendor to request an RMA and tell them you have a S.M.A.R.T. alert. If your disk is under warranty, they will work out the details of a drive replacement.

 

After your replacement is on the way and after you have backed up your data, you may then contact your drive vendor's technical support and ask them to interpret the above information in order to determine either root cause, or expected life. Depending on many factors, they may or may not offer to provide this analysis. (Primarily, they will not bother to do it unless you are a really good customer of theirs, and/or you are having multiple drive failures).

 

You should also be aware that you may have a false error. This is where the S.M.A.R.T. firmware in your drive initiates an alert, but the drive is fine. A common cause of false errors is if your disk drive has had power supply problems, or is exposed to radical temperature changes in a short amount of time. Before shipping your drive off for replacement, you should contact your supplier and ask them to interpret the data to determine if a false error is likely. (It has been our experience that vendors would rather just replace the drive rather than perform this analysis.)

 

Note that the last line contains the hard disk temperature. We can currently only report temperature for most of Maxtor's ATA and SATA disk drives, and some WD disks. Support is added for other disks as we obtain the vendor-specific programming information as we obtain this information.
