Abstract:
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.
