Abstract
In a magnetic or optical disk drive the integrity of data written on a disk is verified by writing data to a portion of the disk, and immediately reading the data from the disk after it has been written. If there is error in reading the data and/or the data read from the disk is substantially different from the data written to the disk an error condition is generated. The error condition may be reporting the error to the host which decides whether to rewrite the data or immediately rewriting the data without further instructions from the host.
