Image Forming Apparatus, and Recording Medium Therefor That Ensure Apparatus Operation without Separation of HDD When Partially Inoperable

A non-transitory computer-readable recording medium storing an image forming program to control a computer of an image forming apparatus including an HDD and a non-volatile semiconductor storage device, the HDD storing user data created by a user, the non-volatile semiconductor storage device storing system data used for operation of the computer, the image forming program causing the computer to function as:

• an HDD confirming unit that detects a failure of the HDD and, in situations where a failure is detected, executes a confirmation process of detecting any operable portion of the HDD;
• and
• a system control unit;
• wherein
• in a failure of the HDD, when the HDD confirming unit does not detect any operable portion, the system control unit separates the HDD from the computer and sets the image forming apparatus into a restriction mode, and
• in a failure of the HDD, when the HDD confirming unit detects an operable portion, the system control unit does not separate the HDD from the computer and sets the image forming apparatus into a small-capacity mode.
