Production of this drive has been discontinued.

The SCSI bus connector on this tape drive is reversed from that on most other SCSI devices. Make sure that you have enough SCSI cable to twist the cable one-half turn before and after the Archive Anaconda tape drive, or turn your other SCSI devices upside-down.

Two kernel code changes are required to use this drive. This drive will not work as delivered.

If you have a SCSI-2 controller, short jumper 6. Otherwise, the drive behaves are a SCSI-1 device. When operating as a SCSI-1 device, this drive, “locks” the SCSI bus during some tape operations, including: fsf, rewind, and rewoffl.

If you are using the NCR SCSI controllers, patch the file /usr/src/sys/pci/ncr.c (as shown below). Build and install a new kernel.

5.7.25 Wangtek 5525ES

The boot message identifier for this drive is WANGTEK 5525ES SCSI REV7 3R1 type 1 removable SCSI 1 density code 0x11, 1024-byte blocks

This is a QIC tape drive.

Native capacity is 525MB.

Data transfer rate is 180kB/s.

The drive reads 60, 120, 150, and 525MB tapes. The drive will not write 60MB (DC600 cartridge) tapes. In order to overwrite 120 and 150 tapes reliably, first erase (mt erase) the tape. 120 and 150 tapes used a wider track (fewer tracks per tape) than 525MB tapes. The “extra” width of the previous tracks is not overwritten, as a result the new data lies in a band surrounded on both sides by the previous data unless the tape have been erased.

This drives quirks are known and pre-compiled into the SCSI tape device driver (st(4)).

Other firmware revisions that are known to work are: M75D
