How to Convert NTFS to HFSby J.S. Copper
NTFS is the standard file system format of Windows-based drives, while HFS (now HFS+) is the standard file system format for Mac OS X-based drives. If you have an NTFS formatted drive, you may notice that it does not play nice with Mac OS X. In order to use the drive with your Apple computer, you'll have to convert the file system format. This can be done using Apple's Disk Utility (included as part of Mac OS X) and will only take a few minutes to complete. Unfortunately, it will erase the contents of the drive, so the drive should be backed up prior to conversion.
Connect the NTFS drive to the Apple computer.
Click the "Finder" icon in the Dock. Select "Go" followed by "Utilities" from the menu bar. Double-click "Disk Utility."
Select the NTFS drive in the "Disk Utility" side bar, and then select the "Partition" tab.
Set "Volume Scheme" to "1 Partition." Select "Mac OS X Extended" as the "Format." Optionally, set a name for the drive and set the desired size.
Click "Apply" to format the drive and convert it to the Mac OS X Extended format.
