Methods and apparatus for facilitating pre-read and/or post-read operations of a disk drive. A write command is received including a logical block address (LBA) for user data in the write command. Parity data for correcting the user data is generated by encoding the LBA with the user data. The parity data is written on a disk of the disk drive with the user data so that the LBA can be recovered using the parity data when read from the disk. When a read command is received by the disk drive, requested user data is read from a first sector. User data and parity data is read from a second sector adjacent the first sector. The parity data is used to recover an LBA for the second sector and it is determined whether to store the user data read from the second sector based on the recovered LBA.
