How does one enable or disable compression on a Sony DDS tape drive?

Answer:

The compression can ONLY be set in the software OR the hardware, not both. If the compression is to be set on the hardware, you will need to set the jumper or dip switch accordingly. The methods to control compression are different depending on the product. (see matrix below)

Products Control Method DC mode 1 DC Mode 2 DC mode 3 DC Mode 4
SDT7000
SDT9000
jumper Not supported Not supported
SDT10000
SDT11000
dip switch

 

 

 


DC mode 1
compression is disabled after power cycle; host control is allowed.
DC mode 2
compression is disabled after power cycle; host control is not allowed.
DC mode 3
compression is enabled after power cycle; host control is not allowed.
DC mode 4
