This could be an indication of future failures and/or potential data loss in bad sectors. Attributes: Drive has a non-zero Raw value ("5 Reallocated_Sector_Ct"), but there is no SMART warning yet. Error Log: Error "Uncorrectable error in data". Usually this means uncorrectable data loss and similar severe errors. Error Log: Drive is reporting 2 internal errors. The device error log contains records of errors. * sdb (Crucial/Micron Client SSDs, Crucial_CT525MX300SSD1, SerNo 1a2b3c4d) * sda (Crucial/Micron Client SSDs, Crucial_CT525MX300SSD1, SerNo 1a2b3c4d) Use -full to get also a warning for notices.Ĭhecked 6 disks. to open the benchmarking tool for the selected drive. From there, select the option Benchmark Disk. Keep in mind that a smartctl run can take up to one or two seconds per disk,ĭepending on its health and (interface/bus) speed.ĭon’t forget to run /usr/sbin/update-smart-drivedb from time to time to get the newest driveĭatabase (sometimes there are improvements on how to interpret some attributes). Once open, use a single click to select your disk from the left hand side of the dialog window, and then click on the 3 vertical dots near the top right of the dialog window (to the left of the minimize button). Disks without SMARTĬapability can be ignored using the -ignore parameter manually. The check tries to identify all disks automatically. Running this check just makes sense on hardware using ATA/SATA and/or SCSI/SAS HDDs and SSDs. Reliability of the hard drive and predict drive failures. The check calls smartctl, which itself controls the Self-Monitoring, AnalysisĪnd Reporting Technology (SMART) system built into most ATA/SATA and SCSI/SAS dd command: It is used to monitor the writing performance of a disk device on a Linux and Unix-like system. No need to provide any warning/critical thresholds, no need to maintain anyĭisk or property databases, no need for any additional libraries.
