摘要： A data storage system and associated method of use may generally be directed to a memory cache that stores a plurality of pending read and write requests. A processor can be configured to prioritize the read requests in the memory cache in response to a sensed acoustic or mechanical vibration in a data storage medium.

摘要： The technology disclosed herein pertains to a system and method for managing write failures in a disc drive. Implementations disclosed herein provide a method including monitoring write fault events per sector for a storage device, in response to a write fault event, updating a write fault repeat count table, wherein the repeat count table tracks a number of write fault repeat counts per sector, comparing a write fault repeat count for a sector to a predetermined threshold write fault repeat count, and in response to determining that the write fault repeat count for a sector is above the predetermined threshold write fault repeat count, performing a write-reassign operation.

摘要： A method includes monitoring operations performed on tracks in a main storage area of a disc, and identifying a track of the tracks in the main storage area susceptible to adjacent track interference (ATI). When a track is identified, the identified track or an adjacent track which contributes to ATI of the identified track is remapped to an ATI safe zone of the disc having a tracks per inch (TPI) density lower than a TPI density of the main storage area.

摘要： Methods and systems that reduce off-track write retry operations in shingled magnetic recording systems. In one implementation, the method includes writing data to an initial track, determining which side of the initial track is a shingled side, calculating a percentage of position error signal (PES) at a shingled side end of the initial track (PES1) when an off-track write operation occurs, determining whether the PES1 meets a first pre-determined threshold, continue writing data to a second track responsive to determining the PES1 is below a first pre-determined threshold, calculating a percentage of PES at a shingled side end of the second track (PES2), determining whether a combined value of PES1 and PES2 is above a second predetermined threshold to determine a probability value of the initial track being erased, and continue writing to a third track if the combined value is below the second predetermined threshold.

摘要： The disclosed technology provides a method that reduces time to recover in storage systems. In one implementation, the method comprises entering an idle status, determining if there is an incomplete band update operation, invalidating a media scratch pad (MSP) by clearing headers responsive to determining there is no incomplete band update operation, performing a power cycle, reading an MSP header, and determining if an MSP header is valid. If a rude power cycle occurs and the MSP header is determined to be valid, an MSP is examined, and restored if required. If a safe power cycle occurs, an MSP restore operation is not required, reducing time to recover.

摘要： Methods, systems, and apparatuses are described for provisioning storage devices. An example method includes determining a write status of an adjacent track that is adjacent to a target track of a shingled magnetic recording (SMR) disk drive. The method may further include determining an offset for a write head based on the write status of the adjacent track and positioning the write head according to the offset.
