    Hi everyone,

    I connected my hard drive to my rmbp 13 today, and tried moving some pictures to it by firstly dragging them, then copying but neither worked, and in the copy option, there was no paste option on the hard drive, but when I try moving from the hard drive to the computer it works. But from the computer to the hard drive it doesnt work. How do I make it to work? Is there a problem? Do I need to authorise something?

    I'm guessing your hard drive was formatted by a windows computer for NTFS.

    If so, you'll need to back it up and format it either in FAT32, ExFat or HFS for it to be usable by OS X.

    Yep I remember using it first on a windows. But how do I do what you said? I didn't understand it, I'm not really the best tech guy;)

    I tried using the disk with time machine, and it said that it needs to format, so I did and it works now :). Thanks

    Hmmm if it was formatted as NTFS, I would have installed Tuxera NTFS (as I would have installed it anyway)

    If the OP intended to use the drive with Time Machine, it would have to be reformatted as HFS+ anyway.

    Format A Hard Drive Using Disk Utility (which is in your /Applications/Utilities folder)

    Choose the appropriate format:

    HFS+ (Hierarchical File System, a.k.a. Mac OS Extended (Journaled) Don't use case-sensitive)

    NTFS (Windows NT File System)
    • Read/Write NTFS from native Windows.
    • Read only NTFS from native Mac OS X
      [*]To Read/Write/Format NTFS from Mac OS X, here are some alternatives:
      • For Mac OS X 10.4 or later (32 or 64-bit), install Paragon ($19.95) (Best Choice for Lion and Mountain Lion)
      • For Mac OS X 10.5 and later, including Lion, FUSE for OS X
      • For 32-bit Mac OS X, install NTFS-3G for Mac OS X (free) (does not work in 64-bit mode)
      • Some have reported problems using Tuxera (approx $36), which is an enhanced version of NTFS-3G with faster performance.
      • Native NTFS support can be enabled in Snow Leopard and later versions, but is not advisable, due to instability.
    • AirPort Extreme (802.11n) and Time Capsule do not support NTFS
    • Maximum file size: 16 TB
    • Maximum volume size: 256TB
    • You can use this format if you routinely share a drive with multiple Windows systems.

    exFAT (FAT64)
    • Supported in Mac OS X only in 10.6.5 or later.
    • Not all Windows versions support exFAT. See disadvantages.
    • exFAT (Extended File Allocation Table)
    • AirPort Extreme (802.11n) and Time Capsule do not support exFAT
    • Maximum file size: 16 EiB
    • Maximum volume size: 64 ZiB
    • You can use this format if it is supported by all computers with which you intend to share the drive. See "disadvantages" for details.

    FAT32 (File Allocation Table)
    • Read/Write FAT32 from both native Windows and native Mac OS X.
      [*]Maximum file size: 4GB.
    • Maximum volume size: 2TB
    • You can use this format if you share the drive between Mac OS X and Windows computers and have no files larger than 4GB.
