LTO Tape Size Differenc

Hi There,

We are using HP MSL4048 with LTO6 tapes. we used to backup some windows servers file level backup & also some VMs.

We have created different pools for daily/weekly file backup & weekly VM backup.  We formatted LTO6 tape and added to file server pool where its shows 2.4 TB or sometimes 2.5 TB of free space.

Where as in VM pool after formatting LTO we get 6TB of free space. i checked the pool properties also, both are same. Still getting this much size difference.

Am I missing something ?
