This is Windows OS limitation. The Window's scsi api does not support
above 64K. You can use a 256K SIZE_DATA_BUFFERS in Linux/Unix land.

Subject: [Veritas-bu] IBM LTO3 Buffer Sizes
I've setup a new environment with IBM LTO3 drives. I set
SIZE_DATA_BUFFERS to 256K, but got an error in the details stating the
drive only supported 64K and the job would not run. Sure enough,
changing it back to 64K allowed the job to run as normal. Others have
said that 256K is supported on LTO3, but I'm not sure what hardware or
OS that is on. Is this an IBM drive thing, a Windows thing, or what? I
would appreciate any ideas.
