    • If the HDD/SSD is not installed in a PC, a USB drive adapter (SATA) can be used. For NVMe and NGFF M.2 SSDs, a specific enclosure is required.

    • If the hard drive is not installed and you do not have a USB adapter, it can be plugged into a motherboard.

    • While high hours are not an indication of failure, these drives are more likely to fail.

    • GSmartControl can be used in Ubuntu if you cannot read the output from Disks.

    • Boot your system into a live Ubuntu session. Locate the Disks application and select the hard disk you want to test.

    • From the drop-down menu, select SMART Data and Self Tests. This will pull up the SMART data.

    • Locate the following SMART attributes: Power On Hours and Power Cycle Count.

    • If Reallocated Sector Count is highlighted and the number is high, replace the drive. Use SMART Extended for accuracy. You will lose capacity and these drives often fail without warning!

    • Locate the following SMART attributes: Reallocated sector count; Current pending sector count.

    • To run a SMART Extended Self-Test, left click Start Self-Test. Select Extended from the drop-down menu.

    • While high hours are not an indication of failure, these drives are more likely to fail.

    • Select Disks from the desktop to open GSmartControl.

    • Select the hard disk you want to test. Click Attributes to read the SMART data.

    • Locate the following attributes: Power On Time and Power Cycle Count.

    • If Reallocated Sector Count is highlighted and the number is high, replace the drive. Use SMART Extended for accuracy. You will lose capacity and these drives often fail without warning!

    • In the Attributes tab, locate the following SMART attributes: Reallocated Sector Count; Reallocation Event Count; Current Pending Sector Count.

    • To test the drive, select Perform Tests. Click Test type: and select Extended Self-Test.

    • Use the error log and SMART data together to diagnose drive problems.

    • Check the error log for drive errors. Click the Error log tab, and review the logs.

    • In the Error log, review the available errors. Read these logs if any are found.

    • When possible, avoid sector wiping SSDs. This will reduce the drive liftetime and can be drastic on older 75TBW lifetime drives.

    • Your erase options are limited to the Security Set options supported by your drive.

    • Drives without ATA Secure Erase will need to be erased externally. Select External and choose Nwipe. Run the DoD Short command (3 wipes+drive blanking).

    • If your drive has a buggy ATA Secure Erase implementation, choose External and erase the drive with Nwipe. SSDs should only be erased with the Secure Erase command.

    • For NVMe SSDs, the best option is to use NVMe Secure Erase.
