    Don't have a solution but would ask what type RAID is being used?
    Might make a difference as to how space is used or reported.
    What is RAID? RAID 0, 1, 5, & 10 Made Easy - The Plug - HelloTech

    From that link:
    If you use a Spanned volume, you can combine two or more hard drives of different sizes to create one large volume. On Spanned, drives are utilize sequentially, meaning data won't be written to the second hard drive until the first hard drive is full.
    That may make one wonder if only one drive is being seen or both drives are. I have 2 x 2TB NAS drives attached to my Router but just as drives, not RAID.

    Are the two 4T drives initiated as GPT or MBR? If they are MBR it will explain as they has a size limit of 2T

    Please post a Disk Manager image as an attachment. Don't forget to expand the columns and to post whole window.
