Disk data management

A system, comprising:

• a data storage system including a disk:
• and
• computer-executable logic operating in memory, wherein the computer-executable program logic is configured to manage disk data, wherein the computer-executable program logic is configured for the execution of:
• obtaining background medium scan (BMS) data from a disk;
• determining a bad sector in the disk based on the BMS data;
• and
• recovering data stored in the determined bad sector.

A computer program product for managing disk data, the computer program product comprising:

• a non-transitory computer readable medium encoded with computer executable program code, wherein the code enables execution across one or more processors:
• obtaining background medium scan (BMS) data from a disk, wherein the BMS data is recorded according to execution of BMS by the disk;
• wherein the BMS data includes a BMS status information and BMS result entries, and wherein determining a bad sector in the disk based on the BMS data further comprises:
• determining a time duration of a last execution of the BMS based on the BMS status information;
• identifying, based on the time duration of the last execution of the BMS, BMS result entries recorded according to the last execution of the BMS from the BMS result entries;
• and
• determining the bad sector in the disk based on the identified BMS result entries;
• determining a bad sector in the disk based on the BMS data;
• recovering data stored in the determined bad sector;
• and
• recovering the data stored in the bad sector determined and relocating the bad sector determined to another available sector of the disk based on redundant array of independent disks (RAID) redundancy.
