External HardDrive - Copying Files

Hi,

I recently started using a Mac Book Air. I have WD external drive, that has files from the windows OS. When I connect the HD to the Air, I can read them fine.

But when I try to Edit, Like want to rename a file on the HD, I see no option to do that. I tried dragging files from the desktop on Air to the HD, it would do nothing.

But when I try to copy/drag files from HD to the desktop, they work fine.

How should I copy files from my MacBook Ait to the External HD?

Welcome to the Mac Forums.

Based on the information you provided, your external hard drive is likely formatted to NTFS which can only be read but not written to by your MacBook Air. It's OK to continue using that hard drive but you'll need a third party driver to be able to read and write to it. The best one is from Paragon Software: "Paragon NTFS" cost is $19.95. After installing the driver, you'll have read and write access from the Air.

NTFS Mounter is Free and words great:
