The 436 has a 6380 tape drive.  This drive writes in QIC2GB format (also
QIC1000, QIC525 & QIC120).  The standard tape you should be using is a
2.5GB, not 2.0 GB.  

Two manufacturers I know of:
3M      - Magnus 2.5
Sony    - QD9250

These tapes provide 2.5GB uncompressed, and approximately 3.5GB with
compression (hardware data compression is standard on the 436).

You can't/shouldn't use any higher density tapes (eg. 3M Magnus 5.0) as
these are intended for different drives.
