I have a 400GB TDK Ultrium 3 tape. I add several libraries to this tape each month. I use the DSPTAP option and print out the tapes contents each month after adding libraries to it.
My question is. How do I determine what's used and what's available (in size). In other words. If the tape has a 400gb capacity in it's native capacity. How many mb, or gb have I used and how many mb, or gb are available. The only thing I see on this tape listing is the file length which I'm unable to translate into mb, or gb.
