ABSTRACT:
A computer system according to the invention includes a posted write cache for writing to a mass storage subsystem. Upon restart, the computer system determines whether the mass storage subsystem has been interveningly written to by another computer system since the computer system last wrote to that mass storage subsystem. If so, the computer system flushes its posted write cache, thus prevent invalid data from being written to the mass storage subsystem.
