HP PCs - SMART Hard Disk Error 301, 302, 309, 30C, 3F1, 3F2 Displays on a Black Screen

This document pertains to HP Notebook PCs with the HP Unified Extensible Firmware Interface (UEFI) beginning in late-2008.
On startup, you might see a message about a SMART Hard Disk error.
Identifying the SMART Hard Disk Error
The SMART Hard Disk test produces 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.
After receiving the error message above, do the following:
  • 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.
  • Run a Hard Drive Test to verify the condition of the hard disk.
If the error code shows 3F0, then see 3F0 Boot Device Not Found Error Appears on a Black Screen.
