For Mac users who also need to use a PC at work, home or just with specific applications, there is a solution. Using Boot Camp Assistant, you can install Windows 7 on your Intel-based Mac computer in its own partition.
On my Windows server machine I have a 1TB drive I want to partition down the middle, one half NTFS and the other HFS+. I don't necessarily need to be able to write or even read the HFS+ partition from within Windows (although I have already installed some drivers to read HFS which do work well), its more just to be used as a dumping ground for the household Macbook backups etc.
I read somewhere that 'GParted' can do this but I wanted confirmation / advice on any alternatives before diving in. I also read somewhere that I would need to create the HFS partition first and then format the remaining space as NTFS? GParted can do part of this. Firstly, defrag your drive and check to see that the end of the drive is free of files. Next boot into a bootable GParted disk. This runs a simple Linux GUI.
Now resize the partition downwards to make room for the new one. Then create your new partition. The bit that GParted will not do is the formatting. For that, you boot into OSX and complete the job. If you don't defrag first, you may find that you don't have as much room to resize the disk as you might have thought.
Especially if the disk has been in use for a while. This is due to fragmentation of the files on the disk. Indeed a heavily used Windows NTFS partition may be a complete 'mess' with chunks of files all over the place. This is rarely an issue to newer versions of Windows, indeed some think Windows may run faster this way! But it may stop you clearing space to do the partition resize. If you don't have a Mac OS to hand to format the partition, you could spend money on but a free way would be to get a bootable Linux CD, should work. I believe the Ubutuntu can format Mac partitions.
If Not, SUSE have a that would allow you to include the hfsutils package.
Back Up the Drive’s Data First First, back up the data on the Mac-formatted drive if you have anything important on it. This process won’t actually convert the file system. Instead, we’ll just be wiping the drive and starting over from scratch. Any files on the drive will be erased. If you have a Mac lying around, you can plug the drive into a Mac and back up the files. If you only have Windows systems available, you can use to copy files from the drive onto your Windows system drive or another drive.
HFSExplorer unfortunately requires you install Java to use it, but it’s the only free option here. You’ll probably want to. Erase the Mac Partitions, Including the EFI System Partition RELATED: First, open the. Press Windows Key + R to open the Run dialog, type diskmgmt.msc into the box, and press Enter to open it. This tool allows you to manage the partitions on drives connected to your computer — internal ones or external ones connected via USB. Locate the Mac drive in the list of disks. Be sure you’ve identified the Mac drive — if you accidentally delete partitions from another drive, you could damage your Windows installation or lose your files.
If you’re lucky, you can just right-click each partition on the Mac drive and select Delete Volume to remove the partitions. You can then right-click in the empty space and select New Simple Volume to create a partition and format it with the Windows NTFS or FAT32 file systems. The Mac drive may have an “EFI System Partition” on it.
This partition is marked as protected, so you can’t just right-click and delete it — the delete option will be disabled. To erase this partition, we’ll have to wipe the entire disk. This process erases everything on the disk, including its files and all its partitions. First, note the number of the disk in the disk management window. For example, in the screenshot below, the Mac-formatted drive is Disk 2. Next, open a Command Prompt window as administrator. To do this on Windows 8 or Windows 7, press the Windows key once, type cmd, and press Ctrl+Shift+Enter.
Type diskpart into the Command Prompt window and press Enter. Type list disk at the DISKPART prompt and press Enter to view a list of disks connected to your computer. Identify the number of your Mac disk in the list. It should be the same as the number of the disk in the Disk Management window.
Be sure to double-check this — you could accidentally wipe the wrong drive if you select the wrong disk here. Type select disk # and press Enter to select the Mac disk, replacing # with the number of the Mac disk. For example, here we’d type select disk 2.
Finally, type clean and press Enter. This command erases the entire selected disk, including all its files and partitions — whether they’re protected or not. You’ll have an empty, uninitialized disk after you do this. Close the Command Prompt window when you see a message saying “DiskPart succeeded in cleaning the disk.” Create an NTFS or FAT32 Partition You can now open the Disk Management window again.
If you’ve left it open, you may have to click Action Rescan Disks to update the data. Locate the Mac disk in the list. It will be completely empty and display a message saying “Not Initialized.” Right-click it and select Initialize Disk. Select the and click OK to create a partition table for the disk. Right-click in the unallocated space on the initialized disk and select New Simple Volume. Use the wizard to create a partition with the. The drive will now be formatted for use by Windows systems.
