Hi,

This is because the lun see gigabyte as 1000 megabytes, rather than 1024 like windows reads it, as well as The file system (format of the hard drive; NTFS, Fat32) itself takes up space too.

if you want to get a disk size of 70GB, you need to create a netapp lun of size: 70x1024: 71680MB

good luck
