new blank disk not showing fully blank

[Chay Walker]

every brand new disk i insert into dvd drive it says only 631mb free on a 700mb blank disk

Many times discs and other storage devices have space reserved for the File System. Try cleaning it in command prompt.

Sounds about right. https://en.wikipedia.org/wiki/Hard_disk_drive#Capacity

MB in labels is 1,000,000 Bytes but the computer does not read the capacity the same way, plus formatting also loses a bit of space vs what the package states. You'd lose about 7% and up in space from what the drive package states to what your computer shows. The larger the drive, the more % of the space you lose. For a 1 TB drive, you are actually only getting a bit over 900GB in what the computer shows.
