ABSTRACT:
An electronic disk subsystem for use with data processing equipment has an electronic disk control unit and an electronic disk unit and compares, in a write mode operation, the address of the last data with the content of a counter which is built in the disk unit. The subsystem, therefore, reliably detects an error which may occur in the counter.
