In that case, the attributes’ names displayed in the ATTRIBUTE_NAME column and the format of the raw attributes shown in the RAW_VALUE column may be incorrect. However, let’s suppose our ATA/SATA drive is not in the database. MODEL FAMILY: Seagate Samsung SpinPoint M8 (AF)ĪTTRIBUTE OPTIONS: None preset no -v options are required.
Match smartmontools Drive Database entry: Smartctl 7.1 r5022 (local build)Ĭopyright (C) 2002-19, Bruce Allen, Christian Franke, Drive found in smartmontools Database. The -P show option displays if the drive is in the database, and if so, its presets, then exits: # smartctl -P show /dev/sdc Instead, SCSI/SAS and NVMe drives do not provide ATA/SATA-like SMART Attributes, so the database doesn’t contain any entries for these drives. The “Vendor Specific SMART Attributes with Thresholds “ table reported by smartctl in the previous section relies on the Smartmontools’ database for ATA/SATA drives. On larger disks, they can take up to ten hours or more. We should proceed with caution with the extended tests because their duration may impact disk wear. In the continuation of this tutorial, we will do a short test. įurther on, we see the estimated times for performing the self-tests: 2 minutes for the short one and nearly 4 hours (215 minutes) for the extended one. However, if we want to enable it, we can run “ smartctl -s on -o on -S on /dev/sdc”. It’s disabled, and we can leave it that way.
TEST HDD HEALTH OFFLINE
“Auto Offline Data Collection” periodically updates specific SMART attributes, but it could impact performance. That’s fine, it means that the disk is still usable. That’s good.Īfter that, we read that the “SMART overall-health self-assessment test result” is “PASSED”.

Vendor Specific SMART Attributes with Thresholds: SMART Attributes Data Structure revision number: 16 Recommended polling time: ( 215) minutes. SMART overall-health self-assessment test result: PASSED SMART support is: Available - device has SMART capability. SATA Version is: SATA 3.0, 6.0 Gb/s (current: 3.0 Gb/s)
Sector Sizes: 512 bytes logical, 4096 bytes physicalĭevice is: In smartctl database ĪTA Version is: ATA8-ACS T13/1699-D revision 6 Model Family: Seagate Samsung SpinPoint M8 (AF) Since smartctl is very verbose, we’ve filtered the following output to highlight the most relevant information: # smartctl -all /dev/sdc Looking for the same information on a virtual disk does not make sense, and it’s not possible. Let’s see an example using the –all flag, which prints all SMART information about a physical disk. Attribute individualism is important because drive architectures vary from model to model.
TEST HDD HEALTH SERIES
SMART technology includes a series of attributes or diagnostics chosen for each drive model. The difference between NAME and KNAME is that the former indicates the device name, while the latter means the internal kernel device name. This tree-like view of partitions is quite intuitive. In this case, /dev/sda contains an LVM with encrypted partitions. Then, for each disk, we can list its partitions with lsblk, for example: $ lsblk /dev/sda -o NAME,KNAME,FSTYPE,MOUNTPOINT,SIZE The detailed information provided by lshw helps us not to be mistaken. First, let’s identify the disks via lshw: # lshw -class disk
There are several methods to find all storage devices. Let’s look at some examples: /dev/hd, /dev/sd, /dev/vd, /dev/nst*, /dev/sg*, /dev/twe, and so on. In the rest of this tutorial, we need to know which device files identify our disks and their partitions.
