ABSTRACT:
A request is received from a caller to perform a read of data from a storage area of a computer system, the data having master header data in a header portion. The master header data is replaced with alternate header data before returning the data to the caller. The data, including the alternate header data, is returned to the caller. A request is received from the caller to perform a write of caller data to the storage area, the caller data having caller header data in a header portion of the caller data. The write of caller data is allowed only if the caller header data is identical to the master header data.
