Abstract
A method in a data processing system for minimizing read/write errors caused by impaired performance of a hard disk drive during runtime operation of the hard disk drive. The runtime operation includes an active mode during which read/write operations are conducted and a standby mode which occurs while no read/write operation is underway. First, at least one performance parameter of a hard disk drive is monitored during a standby mode of operation. Next, in response to detecting a degraded value of the at least one performance parameter, performing preventive recovery action only during the standby mode of operation, such that the performance parameter is restored to an acceptable value without interfering with hard disk drive operation during an active mode.
