Teresa, 
Needless to say, the variable name should be modified according to your drives 
technology.
Example: assuming you have SDLT drives, the variable name will become
NSR_DEV_BLOCK_SIZE_SDLT

In windows 2000 you can set this variable doing some easy steps:
Click right on "My computer" and choose Properties
Choose "Advanced"
Click the "Environment variables" button
Click the button "new" in the lower part of "system variables" pane
In "variable name" enter the name you have "build up" once you have identified 
your drive's technology
In "variable value" just enter 128
Click OK and that's all.

Please check that after having set the variable at least one media initialized 
by those Server/SN has reaaly labeled at 128K. In case it doesn't, there are 
some additional steps to do, involving registry edit. Check listmail archives, 
there's a wonderful page about that.

In Solaris and any other UNIX flavour the variable must be set as any other 
environment variable. I'm not a UNIX expert, so I can't be more precise.

Hope it helps
