Setting the write–protect switch
Travan minicartridges feature a write-protect switch located in the upper left corner
of the cartridge. You can set the switch to keep data from being written on the tape.
Use this switch when you want to make sure that important data on the tape will not
be overwritten.
Figure 4-4 shows the cartridge with the switch in the non-protected (read/write) or
unlocked position.

cartridge or to the unlocked position..
Loading revised firmware from a Seagate firmware cartridge
The STT20000 SCSI minicartridge drive uses flash EEPROM. Flash EEPROM
enables you to download new firmware when revisions to firmware are released.
Firmware revisions are released on specially encoded cartridges that are
automatically recognized by these drives. These firmware revisions are available for
qualified OEMs only from Seagate Technology.
To load a firmware upgrade tape, follow these steps.
1. Power on the host system and the STT20000 drive. Allow the system boot up
process to reach the point where there is no SCSI bus activity.
