A self-healing Hard Disk Drive (HDD) system includes a chassis housing an HDD device self-healing subsystem coupled to an HDD data storage system that includes a plurality of HDD data storage resources. The HDD device self-healing subsystem prevents data from being stored on a first HDD data storage resource that is included in the plurality of HDD data storage resources included in the HDD data storage system. When the HDD device self-healing subsystem determines that data storage operations using a second HDD data storage resource that is included in the plurality of HDD data storage resources will be subsequently unavailable, it remaps logical addresses associated with the second HDD data storage resource to the first HDD data storage resource, and provides the data that was stored using the second HDD data storage resource on the first HDD data storage resource.

A secure one-time programming undo system includes a component and a component configuration system. A one-time programming subsystem in the component configuration system provides the component with personality configuration information that configures the component to perform component operations, and performs a one-time programming operation that configures a component engine in the component to deny modification requests to modify the personality configuration information. A one-time programming undo subsystem in the component configuration system performs a one-time programming undo authentication operation, and transmits a one-time programming undo instruction that is associated with the one-time programming undo authentication operation to the component, with the one-time programming undo authentication operation configured to authenticate the one-time programming undo instruction to the component such that the component executes the one-time programming undo instruction that reconfigures the component engine in the component to allow modification requests to modify the personality configuration information.

A storage device write-read error reduction system includes a computing device that includes a storage device. The storage device determines, at a temperature that is within a predefined temperature range, that a storage device background operation should be performed and, in response, identifies data that is stored in the storage device and that was written to the storage device outside the predefined temperature range. The storage device then prioritizes the data that was written to the storage device outside the predefined temperature range over data that was written to the storage device within the predefined temperature range and, based on that prioritization, performs the storage device background operation to rewrite the data to the storage device.

A device including first firmware of a first type and second firmware of a second type different from the first type. The first firmware configures the device to be installed into a first information handling system associated with the first type. The second firmware configures the device to be installed into a second information handling system associated with the second type. The device is configured to receive a firmware commit command that command includes either a first indication to commit the first firmware, or a second indication to commit the second firmware, but not both indications. The device further determines that the firmware commit command includes the first indication and locks the device to use the first firmware and not the second firmware, and determines that the firmware commit command includes the second indication and locks the device to use the second firmware and not the first firmware.

System and method to provide a single device type in customized products

Systems and methods are provided for implementing one-time programmable features for storage devices. In some embodiments, an Information Handling System (IHS) may include: a processor; and a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution, cause the IHS to: initialize a one-time programmable (OTP) security storage device; and transmit a command to the OTP security storage device, where the OTP security device is configured to be set in security or non-security mode in response to the command, and where the OTP security storage device is configured to deny or ignore any subsequent command to set the OTP security storage device in a security mode or a non-security mode.

One-time programmable features for storage devices

A storage device projected temperature environment configuration system includes storage devices with the same physical hardware configuration, and a computing device manufacturing system that manufactures computing devices. A storage device projected temperature environment configuration subsystem in the computing device manufacturing system identifies a first projected temperature environment for a first computing device being manufactured by the computing device manufacturing system, configures a first subset of the storage devices to perform first storage device operations in the first projected temperature environment, identifies a second projected temperature environment that is for a second computing device being manufactured by the computing device manufacturing system and that is different than the first projected temperature environment, and configures a second subset of the storage devices to perform second storage device operations in the second projected temperature environment that are different than the first storage device operations.

A track map of a disk drive is generated to compensate for various conditions. A track map is a stored measurement of every 'half' servo track width on a disk. Every servo half track width is measured in the factory on a disk and then the data is stored on the disk for use during drive operations. When an individual track is accessed, the appropriate servo half track width data is pulled from memory and is used to adjust a scale factor for that local half track width. The track map may be used to compensate for various conditions including varying servo track width, microjog distance, and data track spacing.

Compensation for variable servo track width

A disk drive uses the integration of the instantaneous velocities of the heads to estimate the distance the heads travel while latched. The disk drive can then determine if the heads are properly parked based solely on the distance traveled, thus avoiding the use of costly sensors. In the event that the heads cannot be properly parked due to some malfunction, the disk drive may store a special code in a nonvolatile memory. The special code directs the controller not to spin up or attempt to load the heads on any disk, preventing the disk from being damaged by the heads.

Preventing damage to the heads and media in a removable cartridge and disk drive

A process for continually compensating for the microjog error resulting from RRO. Typically, the 1F RRO is the most significant, but the method could be applied to the microjog error caused by RRO of other frequencies. The process continually determines an instantaneous microjog error based on the RRO and adjusts the read element target position throughout one revolution, such that the write element remains centered on its intended position.

Method of compensating for microjog error due to repeatable run-out

An apparatus includes a unit that uses a head with spaced read and write portions to write and read information to and from an information storage medium. According to one feature, a desired position for the write element is converted into a position for the read element as a function of a polynomial. According to another feature, the unit uses the head to write and read back selected information in order to determine compensation information, the receiving unit subsequently effecting writing of information with the head as a function of the compensation information. On a more specific level, the unit can removably receive a cartridge that contains the information storage medium.

Method and apparatus for writing with head having spaced read and write elements

A method of inhibiting inadvertent and unauthorized writing and reading of information to and from a storage medium comprises the steps of (a) writing a first code in a predetermined location on the storage medium, the first code being indicative of a first protection mode of the storage medium; (b) receiving a command to change the protection mode of the storage medium from the first protection mode to a second protection mode; and, in response to the command, (c) writing in the predetermined location on the storage medium, in place of the first code, a second code indicative of the second protection mode. A protection mode can inhibit writing to the storage medium, both writing and reading to and from the medium, or neither. Changing of protection modes can also be password protected.
