read-after-write verification
- read-after-write verification
A method of checking that data is written to a hard disk correctly. Data is written to the disk and then read back and compared with the original data still held in memory. If the data read from the disk matches, the data in memory is released. If the data does not match, that block on the disk is marked as bad, and another attempt is made to write the data elsewhere on the disk.
