Tape volume overwrite protection during error recovery

An apparatus, comprising:

• a processor and logic integrated with the processor, executable by the processor, or integrate with and executable by the processor, the logic being configured to cause the processor to:
• detect an error while writing data to a tape volume;
• reposition the tape in response to detecting the error;
• determine, after the repositioning, a current position of the tape;
• and
• determine, based on the current position, whether a rewrite of data associated with the error to the tape volume is allowed.

A computer program product for protecting overwrite of a tape volume, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a controller to cause the controller to perform a method comprising:

• detect, by the controller, an error while writing data to a tape volume;
• reposition the tape in response to detecting the error;
• determine, by the controller after the repositioning, a current position of the tape;
• and
• determine, by the controller based on the current position, whether a rewrite of data associated with the error to the tape volume is allowed.
