    Recently bought a Samsung M3 Portable Hard Drive and apparently I have to download a NTFS driver, I did and time machine still tells me the disk is not in mac format.


    Any help?

    Time Machine requires the Mac OS Extended (Journaled) format. Just attach the drive and open Disk Util and select the drive on the left then go to the erase tab and select Mac OS Extended (Journaled) ion the drop down then click erase and you will be all set to use the drive with Time Machine.

    NTFS is only if you need to use the drive in Windows.

    I have heard by doing so it limits file uploads per time to 4GB?

    No... I think what you may have read somewhere is the old 4GB file size limit of FAT32. That limit does not apply to either NTFS or the Mac OS Extended (HFS+) formats.

    Ah ok I see. Will this maintain read/write capability on Windows machines as well?

    No... if you format the drive to HFS+ to use form Time Machine, it won't work in Windows by default, but you can buy software like this that would allow read/write with Windows and HFS+.

    I know you want to use the drive for Time Machine, and that does require HFS+ on the Mac, but what are you trying to do with the drive in Windows? If you want to use that same drive to swap some files back and forth between Mac and Windows you could make one partition in HFS+ for Time Machine, then a second partition in the ExFAT format that both Mac and Windows can read/write by default.

    On the Samsung M3 Portable H/D 1Tb that I bought recently, will only work on the first mac I used on but not on my other mac. Is it too late to change for use of both ??

    What Macs are they? What file system are you running?

    And which one isn't recognising the drive? Is the drive seen in Disk Utility?

    not recognized on the second Mac, the desktop. Disk Utility sees it OK on the Macbook the first computer but on the second one , while the name appears no buttons are highlighted in order to verify or any of the others to edit.

    Out of interest, where is this "helpful" bit of advice coming from? I ran into someone who'd done the same.

    I currently use macbook pro and own Samsung M3, Ive just plugged in my M3 for the first time in a while and it has formatted to NTFS. Why would this happen? I need to now revert it back so I can use on my Mac which I done for months and I can't afford to erase all the contents on it...what should I do?

    I imagine NTFS out of the box.

    If ever you used a different file system with the drive, I can't imagine destruction of that file system without the knowledge of a user.
