TSM tracks only how much data it has written to the drive/medium: it has no knowledge of what the storage hardware actually did to store the data.
I am trying to obtain this information so that it will give me a compression value of data transferred to tape (if any)
You know the native, physical capacity of such media, and you know how much TSM has written to it when it reaches a Full state... Richard Sims http://people.bu.edu/rbs
