Http://www.linuxsir.org/bbs/showthread.php?s=&threadid=81020 Werix Monitoring your hard disk-SMART early warning system Foreword : Psychological fear most is not that we install a system, but hard to install, bad hard disk suddenly one day, No backup (DAT, DLT tape like you have scary). How you will be able to know whether a new hard disk Years? (Hard disk state? ), Especially if the early warning, telling us not stand a fast hard disk, Nice. Solution : SMART SMART (SFF-8035i) is a hard disk manufacturers have established industry standards, the standard is a hard disk protection With the implementation of a deposit, reliability, error rate and other attributes of time to find form. All attributes have a 1byte (the The small-scale 1-253), the value of standardization, it also includes another 1byte critical stage of value, if certain attributes form Data values close to or less reached a critical stage, then your hard drive quickly with you forever, or at least more than it Limit the use of the design - and the worst case scenario is to do a backup. After ATA-3 SFF-8035i industry standards, the ATA-5 ATA-4 adding an erroneous message (error Log), and self-rated series hard disk SMART orders. SMART meet with IDE and SCSI hard disks. I used to do the experimental FreeBSD 5.2, and Debian, has been pretty good, can be directly used atactl OPENBSD Now, let us look at the man atactl or below the message. No other Linux system, we can see the end of this paper to the official website inquiries Your system. 1.

This article is based on an English magazine "Linux Journal January 2004" - Monitor drive health with SMART, author Bruce Allen is a professor of physics. I wrote the article because of better times than my own notes, so I decided to refer to some examples of the original order.
