    Overwrite exFAT format of 8TB external drive with NTFS?


    I have an external WD 8TB My Book: My Book - External Hard Drive | Western Digital (WD)

    It is formated in exFat. Could I do a quick format with NTFS? Would this cause any drawbacks?

    It won't cause any drawbacks other than erasing everything that is currently on the drive. I would start with the clean command in diskpart. Just make sure you have the correct drive selected!

    Thank you!

    Unfortunately I do not have any idea of diskpart. Why is it better to use that one, why not the Win partition manager? The clean command? To delete the content of the drive? Anf after formating? Why?

    Is there an adavantage of using NTFS? There are some programs (indexing) obviously running much faster with NTFS.

    Many thanks again

    The clean command just resets everything so nothing left behind would interfere with it in the future. You run it from a command prompt (admin) or "run as Administrator" command prompt. Then:

    Diskpart
    List disk
    Select disk # -replace # with the actual number of the 8tb drive
    Clean - this will erase the selected disk
    Convert gpt
    Create part pri
    Format fs=ntfs quick
    Assign
    Exit
    Exit

    Thank you very much!

    I am afraid I have any idea of such commands and how to serve that command prompt, very sorry.

    Main difference between exfat and ntfs is that exfat drives can be read on a mac as well. If you do not need that functionality, ntfs is generally more efficient.

    Yes, I do not need the drive for Mac, for Win only.

    ntfs is generally more efficient
    What does it do better?
