I just purchased a Samsung Story 1.5TB hard drive. I was planning on formatting as NTFS and using it as a pc backup (My 750 gig HD is full), until I went to format it on my vista pc. I saw I had an option to format as exFAT and know FAT32 works in OS X, and was wondering if exFAT will work on OS X also?

Or should I wait until Apple activates NTFS writing on OS X?

24inch 3.06Ghz iMac. 4 gigs of RAM. 1TB HD., Mac OS X (10.5.7), Hp Pavilion dv7t. Windows Vista Ultimate 64 bit.

    no. I'm not even sure OS X will read it. I think not. there maybe some third party drivers provided by something like MACFUSE but you'd have to search for that.

    either that or use the hack that activates NTFS writing now.

    Warning: it is extremely buggy so I wouldn't go there. other options are to use NTFS-3g or NTFS for Mac by Paragon.

    and of course you can use FAT32.

    There really isn't any benefit in using exFAT for an external hard drive. It was really designed to optimize performance on external flash drives. You can use NTFS or FAT32 (which has a 4GB maximum single filesize limit).

    ok, thanks guys.

    I think I might just go with NTFS and wait for apple to activate its writeablity.

    Note that if you are willing to use MacDrive (mediafour.com), a great program that I have used for years, on your PC, then you can read and write Mac formatted drives using the PC. Thus, if you format the drive Mac extended (journaled), then both machines will be able to use the drive.
