SDLT 220 and SDLT 320 Compatibility Issues
For more information about what happens when a 320-formatted cartridge is 
inserted into a SDLT 220 drive, refer to Section A.7, “Overwriting 320-Formatted 
Super DLTtape I Data Cartridges” on page A-11.
Forcing Tape Density with MODE SELECT Parameters
The Default Density Override parameter on the Vendor Specific Configuration 
Page (25h) can be used to override the default density for the tape until a new data 
cartridge is loaded.
NOTE: For more specific information about tape density codes, 
refer to the SCSI command descriptions for MODE 
SELECT and MODE SENSE. You can find these in a 
separate document published by Quantum, SDLT 220 and 
SDLT 320 SCSI Interface Guide, 81-85001-01.
