External hard drives, thumb drives, USB drives, Flash memory cards, and devices like iPod are examples of storage devices that you can connect to your Mac using Thunderbolt, USB, or USB-C cables, or connect wirelessly using Bluetooth wireless technology.

Storage devices (such as external hard drives) can also be available on your network. Additionally, you can insert flash memory cards from your camera or other device in the SDXC card slot in your Mac. If your Mac doesn’t have a card slot, you can access the data on the flash memory card using a connected card reader.

After you connect your storage device, you can move files from your Mac to the storage device or from your storage device to your Mac.

If your Mac has a USB-C port, see Use USB-C cables with your Mac.

When I copy files from macOS X to a USB external hard drive disk with both command or drag and drop action, the operation can not be processed. After some time investigate with google, I finally found the reason. This article will tell you how to resolve can not copy files from macOS to USB external hard drive disk issue.

1. Format The USB Disk With ExFat File Format.

The main reason for this issue is macOS can only read NTFS format files but can not write files to NTFS disk. So if the USB disk is NTFS format, then the copy and paste operation can not be operated. So we should change the USB Disk file format to others such as FAT or ExFAT. And ExFat is a more good choice.

Copy Photos From Mac To External Hard Drive

1.1 Change USB Disk File Format Steps.

  1. Open macOS Finder —> Applications —> Utilities —> Disk Utility.
  2. Select the USB disk in the left panel.
  3. Then click the Erase button at the top of the right panel. Select ExFAT in the Format drop-down list and begin to format.
  4. After the format process complete successfully, you can copy files from macOS to USB disk successfully.

2. Install NTFS-3G To Make MacOS Support Read-Write Microsoft Windows NTFS File System.

  1. Open a terminal and run the command $ brew install ntfs-3g to install NTFS-3G.
  2. Unmount the existing NTFS format partition if needed.
  3. Create a directory as the mount point volume label for the NTFS partition.
  4. Run /usr/local/bin/ntfs-3g command to mount the NTFS disk partition with the above mount point manually in read-write mode.
  5. You can also run the /usr/local/bin/mount_ntfs command to mount the NTFS disk partition as below.

3. How To Copy Files From macOS To USB External Hard Drive In Command-Line.

Copy File From Mac To External Hard Drive

  1. Open a terminal and run the command cp -R Documents /usb.
  2. The -R parameter will copy all the subdirectories under the Documents directory to the USB external hard drive.
  3. But above command may raise an error message such as usb/Pics: No such file or directory.
  4. This is because the USB external hard drive is mounted under /Volumes folder, so you should add the /Volumes directory before USB disk name when you run the cp command.
