    I have an external hard drive that I used on my windows laptop. Now that I have a mac it acts different. One difference is I can not drag and drop a folder with movies in it on the the ext hd from my mac. I get the circle with a slash through it. Is this because it is formatted to work with windows? How do I correct this? I tried using win 8 on parallels and it says I need permissions but I don't see that option to okay it. Can I get some help please? Thx.

    Yes. Your Mac can natively read, but not write to NTFS-formatted drives.

    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.

    Read the bold text in my response. You don't need to reformat the drive to retrieve the files.

    If you want to format or reformat a drive, this will help:

    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)

    • 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.

    Yes, copy the files/folders of the HDD onto another properly formatted HDD or your Mac's internal HDD, then use Disk Utility to format it appropriately and copy the data back.
