    Basically I just got myself the latest MacBook as an upgrade from an old laptop. With my old laptop I had no problems what so ever when using my external hard drive. To delete any files I didn't want I would just right click and press the delete option. However, when connected to my new Mac, there is no such option when right clicking on a file. I've tried dragging the file to a recycling bin but I get a message from the finder saying this file can't be deleted. I've tried moving the file out of my hard drive which worked and then deleting it which was fine but the file remained in the external hard drive as I'd only created a copy. I can't figure out how to delete files I don't want. Deleting everything on the hard drive is out of the question. Any help would be greatly appreciated.

    Thank You.

    Ross.

    Ehh, This might work. Not sure though.

    Right click on the Drive and then hit Get info. Look towards the bottom at Sharing/Permissions and make sure it says Read & Write.

    If you used that HDD with Windows and formatted it with Windows or bought it for a Windows machine, it might be formatted with NTFS, a Windows file system, which Mac OS X can only read, thus you can't delete files/folders.
    To be able to write to NTFS formatted volumes, use NTFS-3G (free).

    Having same issue


    I did this and it said READ ONLY. with no option to choose Read and Write.

    So the question is, how do we get it to say READ AND WRITE?

    Did you read the other posts? You need to check to see if the external HD is formatted NTFS - that's usually what causes the problem.

    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 (approx $20) (Best Choice for Lion and later)
      • For 32-bit Mac OS X, install NTFS-3G for Mac OS X (free) (does not work in 64-bit mode)
      • For 64-bit Snow Leopard, read this: MacFUSE for 64-bit Snow Leopard
      • Some have reported problems using Tuxera (approx $36).
      • Native NTFS support can be enabled in Snow Leopard and Lion, 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.

    I am searching here as I just ran into this problem as the OP. And yes this hard drive was formatted for a windows machine.

    GGJ-
    Is this app still relevant? I want to delete stuff from my External without losing anything when formatting or whatever. I want to just manually delete certain stuff from it.

    Hey guys,

    If formatted to NTFS 3G, would it be recognised by Windows if needed to be used ??

    I just now saw your post from over a year ago. I've updated my previous post to include more current information. I recommend Paragon for reading, writing and formatting NTFS drives from OS X.
    Yes.
