    Hey Guys,

    I have a 1TB WD Hard drive which is in NTFS format at the moment.

    I want to format this to FAT / FAT 32.

    Someone told me that FAT / FAT32 would not be able to format a whole TB.

    What is the maximum size can be formated ?

    8TB is max volume size.

    4GB-1byte is the max file size.

    If you plan on wanting to store any files larger than 4GB on the drive (i.e.: Dual layer DVD ISO images,) then FAT32 isn't going to work for you. Other than that, you should be fine.

    Okay , this is what i want to achieve with the 1 TB WD.

    I have my mac book pro of which i use it to dj with serato.

    i also have a windows desktop i use.

    I cant build crates in serato with the HD on the mac due to the NTFS, so because this HD is strictly for music purposes , i want to format the entire drive to FAT.

    So , am using my Windows desktop to do the formatting , i go to my computer and right click on the HD i am seeing exFAT and not FAT or FAT 32.

    exFAT and FAT32 share the same limits. You would want to look at the Windows XP link I posted to get the more accurate depiction of what those are for exFat.

    exFAT is Microsoft's format that they created for external flash-based media (USB keys, mainly, but any external USB storage device such as a mechanical drive inside a USB enclosure like what you have would follow the same guidelines.)

    When I say 4GB, I mean a single file (i.e.: an mp3 file.)
