Abstract
A method for assuring data write integrity on a data storage device includes storing data in a temporary memory storage medium after receipt of the data and prior to writing the data to a storage device. After the data is written to a storage device, the data itself, or an error checking and correction code is read and compared with the original data or with the data error checking and correction code. If no error occurs, new data is received written, read and compared. If an error has occurred, the method re-writes the data to the same or a re-assigned location on the data storage device prior to writing, reading and comparing the data again. Thus, data is written and compared prior to removing the data from a temporary memory storage medium to assure data write integrity.
