Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error SMART Self-test log structure revision number 1 The smartctl command reports a badblock at Logical Block Address LBA = 0x016561e9 which in decimal number system is 23421417. This article proceeds through some examples of disk failure for different types of filesystem. The usage of this command will be clear as we proceed through this article. The smartctl performs SMART tasks and can be used to print SMART self-tests and error logs among other tasks such as support for polling TapeAlert messages from SCSI tape drives. Smartd is the deamon that polls the ATA and SCSI devices every 30 minutes (this value can be changed) and logs the SMART errors and changes in SMART attributes using SYSLOG interface. The smartmontools package provides two utilities: smartrd and smartctl. This tutorial describes the actions that can be taken when smartmontools detect and report some badblocks on hard disk running linux. The SMART stands for Self-Monitoring, Analysis and Reporting Technology. The SMART technology built into many storage devices (such as many ATA-3, later ATA, IDE and SCSI-3 hard drives) monitors the reliability of hard drive and can predict drive failures. These badblocks can be recovered if we are able to reach the exact location of that block. The badblocks in a storage device are the portions of the device that are not readable for some reason.
