Abstract
Technologies are described herein for performing flexible virtual defect padding of bad sectors on recording media of a storage device. A defective sector on a data track of a recording medium in the storage device is detected. The size and position of a physical defect within the defective sector are determined, and one or more sectors adjacent to the defective sector on the data track are mapped as virtual defects based on the size and position of the physical defect within the defective sector.
Claims20
A method comprising steps of:
- detecting a defective segment on a data track of a recording medium in a storage device;
- determining a size and position of a physical defect within the defective segment ;
- and
- mapping one or more adjacent segments on the data track as virtual defects based on the size and position of the physical defect within the defective segment, the one or more adjacent segments being adjacent to the defective segment.
A non-transitory computer-readable medium having processor-executable instructions stored thereon that, when executed by a processor, cause the processor to:
- detect a defective sector on a data track of a recording medium in a storage device;
- determine a size and position of a physical defect within the defective sector;
- and
- map one or more adjacent sectors on the data track as virtual defects based on the size and position of the physical defect within the defective sector, the one or more adjacent sectors being adjacent to the defective sector.
A system comprising:
- a hard disk drive comprising a recording medium;
- a processor operably connected to the hard disk drive;
- and
- a virtual defect padding module operably connected to the hard disk drive and the processor and configured to
- detect a defective sector on a data track of the recording medium,
- determine a size and position of a physical defect within the defective sector, and
- map one or more adjacent sectors on the data track as virtual defects based on the size and position of the physical defect within the defective sector, the one or more adjacent sectors being adjacent to the defective sector.
