MAGNETIC TAPE REWIND OVERWRITE DATA PROTECTION |
| 摘要 |
A computer-implemented method for preventing overwriting of data, e.g., on a magnetic medium, includes receiving a write command to write to a magnetic tape. The current location of the magnetic tape is determined. A determination is also made as to whether data corresponding to the write command is at least one of: a size and type specified for a block at the current location. Execution of the write command is disallowed in response to determining that the data corresponding to the write command is not of the specified size and/or type. |

1. A computer-implemented method, comprising:
receiving a write command to write to a magnetic tape; determining a current location of the magnetic tape; determining whether data corresponding to the write command is at least one of: a size and type specified for a block at the current location; and disallowing execution of the write command in response to determining that the data corresponding to the write command is not of the specified size and/or type. |
