Dynamic media cache for a data storage drive in an information handling system

An information handling system comprising:

• a data storage medium including at least one disk platter, a storage space, and a cache space;
• a processor;
• and
• a non-transitory computer-readable medium comprising instructions that, when read and executed by the processor, are configured to cause the processor to:
• receive a command from a host to write a set of data to the storage space of the data storage medium;
• determine that insufficient space is available in the cache space of the data storage medium to write the set of data to the cache space;
• in response to determining that insufficient space is available in the cache space of the data storage medium to write the set of data to the cache space, determine that an available portion of the storage space is available, the available portion of the storage space previously formatted in a first format that includes track sections of the at least one platter such that at least one particular track section overlaps with at least one neighboring track section;
• in response to determining that the available portion of the storage space is available, reformat the available portion of the storage space to convert the available portion of the storage space into a dynamic cache space formatted in a second format that includes track sections of the at least one platter such that the least one particular track section does not overlap with any neighboring track sections, wherein the dynamic cache space remains visible to the host as the available portion of the storage space;
• and
• after reformatting the available portion of the storage space into the dynamic cache space formatted in the second format, write the set of data to the dynamic cache space.

An article of manufacture comprising:

• a non-transitory machine-readable medium;
• and
• instructions on the non-transitory machine-readable medium that, when read and executed by a processor, are configured to cause the processor to:
• receive a command from a host to write a set of data to a storage space of a data storage medium, that includes at least one disk platter, associated with a drive controller;
• determine that insufficient space is available in a cache space of the data storage medium to write the set of data to the cache space;
• in response to determining that insufficient space is available in the cache space of the data storage medium to write the set of data to the cache space, determine that an available portion of the storage space is available, the available portion of the storage space previously formatted in a first format that includes track sections of the at least one platter such that at least one particular track section overlaps with at least one neighboring track section;
• in response to determining that the available portion of the storage space is available, reformat the available portion of the storage space to convert the available portion of the storage space into a dynamic cache space formatted in a second format that includes track sections of the at least one platter such that the least one particular track section does not overlap with any neighboring track sections, wherein the dynamic cache space remains visible to the host as the available portion of the storage space;
• and
• after reformatting the available portion of the storage space into the dynamic cache space formatted in the second format, write the set of data to the dynamic cache space.
