Write pointer management for a disk drive including a disk having a plurality of sectors and a non-volatile memory (NVM) for storing data. Data is sequentially written sector by sector on the disk. The data written in a sector includes a write status indicator indicating that data has been written in the sector. A write pointer is stored on the disk or the NVM as a check-pointed write pointer. The write pointer corresponds to a current sector for writing data on the disk. During a write pointer recovery process, the check-pointed write pointer is retrieved, and at least one write status indicator is scanned in a range of sectors from the sector corresponding to the retrieved check-pointed write pointer and a last sector to identify the current sector for writing data. The write pointer is set to correspond to the identified current sector.
