1. A computer-implemented method for altering a current position in a Data Partition of a tape at which the tape transitions to a DATA_FULL state, comprising:
determining a size of an Index to be appended to an end of file data written to the Data Partition of the tape; and
altering, based on the size of the Index to be appended to the end of the file data written to the Data Partition of the tape, the current position in the Data Partition of the tape at which the tape transitions to the DATA_FULL state to a new position in the Data Partition of the tape at which the tape transitions to the DATA_FULL State, wherein the DATA_FULL state is a state on the tape in which only metadata write operations are permitted in the Data Partition.
