Claim 10:
11. A computer system for unoptimized tape drive read detection, the computer system comprising:
one or more computer processors;
one or more computer readable storage media; and
computer program instructions, the computer program instructions being stored on the one or more computer readable storage media for execution by the one or more computer processors, and the computer program instructions including instructions to:
determine whether a read order of a trio of consecutively read related files is consistent with an order in which the trio of consecutively read related files are stored on a magnetic tape media, wherein the read order of the trio of consecutively read related files is determined to be consistent with the order in which the trio of consecutively read files are stored on the magnetic tape media based on:
comparing the read order of the trio of consecutively read related files to a starting block number of each file in the trio of consecutively read related files, and
determining that either the starting block number of each file in the trio of consecutively read related files increases or that the starting block number of each file in the trio of consecutively read files decreases; and
responsive to determining that the read order of the trio of consecutively read related files is inconsistent with the order in which the trio of consecutively read related files are stored on the magnetic tape media:
generate an unoptimized tape drive read warning.
