Installing internal tape drives Re viewing Drive Default Settings 23 Data Compression The internal tape drive provides two sw itches for controlling data compression. Switch 1 determines whether hardware data compress ion is enabled or disabled. By default, switch 1 is set to ON, enabling hardware data compressi on.
Installing internal tape drives Re viewing Drive Default Settings 24 Power -On Self-T est Switch 4 en ables or disabl es the Pow er-O n Self-T est diagnostics tha t the drive performs when pow- ered on. By default, the drive responds to SCSI commands only after it successfull y completes the Power-On Self-T est (abou t 5 seconds).
Installing internal tape drives Recording Drive Information 25 SCSI W ide/Narrow Configurat ion (DDS-4 Drives Only) Switch 9 enables SCSI Wide or Narrow operation. By default, switch 9 is set to ON, enabling SCSI Wide (16-bit) operation. T o enab le SCSI Narrow (8 -bit) operation, set switch 9 to the OFF position.
Installing internal tape drives Accessing the Inside of Y our Computer 26 Accessing the Inside of Y our Computer T o gain acc ess to the inside of your computer: 1. Shut down the computer as you would normally . Then turn off the computer and all peripherals connected to it.
Installing internal tape drives Mounting the Internal T ape Drive 27 4. Secure the drive in the mounting bay using two M3 .0 metric screws on each side of the drive (see Figure 5 on page 27). As Figure 6 on page 27 shows, the 3.5-inch drive has four screw holes on the bottom and five on each side.
