1. A method comprising:
- activating a display mounted on a hard disk drive assembly, said activating comprising detecting that a control is engaged at a first time;
obtaining usage context from a cache of said hard disk drive assembly in response to said activation of said display mounted on said hard disk drive assembly, wherein the usage context comprises a rank status in a RAID configuration, the rank status including an indication of whether the rank is in one of a plurality of modes, the plurality of modes comprising a normal mode, a failed mode, a degraded mode, and a rebuilding mode; and
information of an amount of free space in the cache, a microcode in the cache, hardware levels of the cache, a spin-up status of said hard disk, an operator that configured the rank, and a rotational velocity of said hard disk;
displaying on said display mounted on said hard drive assembly at least a portion of said information obtained from said cache;
determining, at a second time, if said control is engaged; and
in response to determining that said control is not engaged, powering off said display, wherein said second time is greater than a predetermined time threshold time after said first time.

Abstract
Methods and systems are provided for displaying information on a hard disk drive assembly. One hard disk drive assembly includes a hard disk drive that includes a driver circuit coupled to a display and to a display memory. The driver circuit activates the display mounted on the hard disk drive assembly. In response to the activation of the display the driver circuit obtains information from the display memory of the hard disk drive. The driver circuit displays at least a portion of the information obtained from the display memory on the display mounted on the hard disk drive assembly.

8. A hard disk drive assembly comprising:
-
a hard disk drive comprising; a display; a display memory comprising a cache; a driver circuit coupled to said display and said display memory, wherein said driver circuit is configured to; activate said display mounted on said hard disk drive assembly, obtain usage context from said cache in response to said activation of said display mounted on said hard disk drive assembly, wherein the usage context comprises a rank status in a RAID configuration, the rank status including an indication of whether the rank is in one of a plurality of modes, the plurality of modes comprising a normal mode, a failed mode, a degraded mode, and a rebuilding mode; and
information of an amount of free space in the cache, a microcode in the cache, hardware levels of the cache, a spin-up status of said hard disk, an operator that configured the rank, and a rotational velocity of said hard disk, anddisplay at least a portion of said information obtained from said cache on said display mounted on said hard disk drive assembly; and a control coupled to said driver circuit, wherein said driver circuit is further configured to; perform said activation by detecting said control has been engaged at a first time, determine if said control is engaged at a second time, and in response to determining said control is not engaged, power off said display, wherein said second time is greater than a predetermined time threshold time after said first time. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A non-transitory computer-readable medium comprising a computer program product for displaying information related to a hard disk drive assembly, comprising:
-
computer code for activating a display mounted on the hard disk drive assembly, said computer code for activating the display comprising computer code for detecting that a control is engaged at a first time; computer code for obtaining usage context from a cache of said hard disk drive assembly in response to said activation of said display mounted on said hard disk drive assembly, wherein the usage context comprises a rank status in a RAID configuration, the rank status including an indication of whether the rank is in one of a plurality of modes, the plurality of modes comprising a normal mode, a failed mode, a degraded mode, and a rebuilding mode; and
information of an amount of free space in the cache, a microcode in the cache, hardware levels of the cache, a spin-up status of said hard disk, an operator that configured the rank, and a rotational velocity of said hard disk;computer code for displaying on said display mounted on said hard drive assembly at least a portion of said information obtained from said display memory; computer code for determining, at a second time, if said control is engaged; and computer code for powering off said display in response to determining that said control is not engaged, wherein said second time is greater than a predetermined time threshold time after said first time. - View Dependent Claims (16, 17, 18, 19, 20)
