HP PCs - SMART hard disk error 301, 302, 309, 30A, 30B, 30C, 3F1, 3F2

The computer runs a SMART Hard Disk test during startup. If there is a potential hard disk issue, you might see an error message displayed on a black screen.

SMART hard drive error warning message

The SMART Hard Disk test creates a prediction about the potential for hard drive failure, not an actual failure. A SMART Hard Disk error warning can occur for a variety of reasons, such as the computer having been jarred sharply or the hard disk being subjected to higher than usual temperatures.

If you receive this error message, perform the following actions:

  1. Immediately back up all important data and files. While the SMART hard disk error might not indicate the imminent loss of the hard disk, it is best to be prepared, just in case the disk does fail.

  2. Run a Hard Disk Test to verify the condition of the hard disk.

If the error code includes 3F0, then see HP PCs - 3F0 boot device not found error displays on a black screen in Windows 10.

Back up your data

In Windows 10, use the File History backup feature to back up to an external drive or network location.

For more information, see Backup and Restore in Windows 10 (in English).

  1. In Windows, search for and open Backup settings.

  2. Click Add a drive. Windows searches your computer for usable backup drives.

  3. Choose an external drive or network location to store your backup files.

Perform hard drive tests in HP PC Hardware Diagnostics

HP PC Hardware Diagnostics provides multiple tests to test the hard drive on your computer and confirm hardware failures. First, run the Quick Test (two to three minutes).

  1. On the Component Tests menu, click Storage > Quick Test.

    Selecting the Hard Drive Quick Test
  2. Click Run once. The Quick Test begins.

  4. If the hard drive passes the Quick Test, but there is still a problem with the hard drive, run the Extensive Test. This test includes the SMART Check, Short DST, Optimized DST, and Long DST. To run these tests individually, select them from the Hard Drive Tests menu.

  5. If the hard drive fails a test, click Troubleshoot.

  6. Follow the on-screen instructions to attempt to resolve the problem, and then click Yes.
