| BOT | The tape is positioned at the beginning of the first file. |
| EOT | A tape operation has reached the physical End Of Tape. |
| EOF | The tape is positioned just after a filemark. |
| WR_PROT | The tape (or drive) is write-protected. For some drives this can also mean that the drive does not support writing on the current medium type. |
| ONLINE | The drive has a tape in place and ready for operation. |
| DR_OPEN | Door is open. Depending on the type of drive, this usually means that the drive does not have a tape in place. |
| IM_REP_EN | Immediate report mode. This bit is set if there are no guarantees that the data has been physically written to the tape when the write call returns. It is set to zero only when the driver does not buffer data and the drive is set not to buffer data. |
| SM | The tape is currently positioned at a setmark. DDS specific. |
| EOD | The tape is positioned at the end of recorded data. DDS specific. |
