Windows 10

Before you can access a new or formatted drive in your operating system, you need to initialize it first and then create a partition on the drive. A partition defines an area of the drive to use for storing data. The partition uses a file system (for example, ex-FAT, NTFS, and so on).

Initialize a drive

Note: You typically only need to initialize a drive if the drive is new. If you cannot find an uninitialized drive in Disk Management, skip the following steps and try to partition your device.

  1. Press the Windows key + R, type compmgmt.msc, and click Run to open Computer Management.

  2. Navigate to Disk Management.

  3. When prompted to, initialize your disk(s). If you are running Windows® 7 or later and are using a drive larger than 2TB, initialize the disk(s) with GPT. If you are running an earlier version of Windows, initialize the disk(s) with MBR. For more information, visit the following FAQ: https://www.startech.com/support/faqs/technical-support?topic=hard-drives#mbr-vs-gpt.

  4. Click OK.

Create a partition in a drive

Note: The following steps create an NTFS partition that uses the entire drive space. To use a different file system, select a different option in step 6.

  1. Right-click Unallocated or RAWvolume, and select New Simple Volume.

  2. In the New Partition Wizard, click Next.

  3. Select Primary partition.

  4. Leave the partition size set to default, and click Next.

  5. Assign a drive letter or leave it set to the default, and click Next.

  6. Enter the following settings to format the partition:

  • In the File System field, enter NTFS.
  • Set the Allocation unit size to Default.
  • In the Volume label field, enter <your name/reference>.
  • Select the Perform a quick format check box.
  • Clear the Enable file and folder compression check box.
  1. Click Next > Finish.

The new drive should appear in Windows Explorer.

Mac OS

Before you can access a new or formatted drive in your operating system, you need to initialize it first and then create a partition on the drive. A partition defines an area of the drive to use for storing data. The partition uses a file system (for example, HFS+, ex-FAT, NTFS, and so on).

Initialize a drive

Mac OSX detects a drive that needs to be initialized and automatically prompts you to initialize the drive. If you are prompted to initialize the drive, click Initialize. If you are not prompted to initialize the drive and you cannot find the drive in Finder, you will need to create a partition on the drive.

Create a partition on a drive

Note: The following steps create an HFS+ (Mac OS Extended (Journaled)) partition that uses the entire drive space.

To create a partition on a new drive, complete the following:

  1. Open Finder.

  2. Navigate to Applications and click Utilities.

  3. Open Disk Utility.

  4. Select the new drive and click the Partition tab.

  5. Click Options and verify that it is set to GUID Partition Table.

  6. Enter a name for the partition.

  7. Click Partition.

The drive should now be accessible in Finder.

Hello,

My wife has an iMac with OS X Lion on it. We partitioned her HD to run bootcamp with Windows 7 to play some games. Bought a Seagate Backup Plus external USB HD for extra space for games on the Windows 7 end and Time Machine for her iMac. Time Machine does not work with the Paragon driver the ext HD came with so I decided to partition it into two parts; one for Mac, the other for Windows.

I looked up about the different HD formats for Mac and Windows. Used Disk Utility to partition the ext HD 50/50. Named the top partition Mac and chose the format Mac OS Extended (Journaled), named the bottom Windows and chose the format NTSF.

After running Time Machine on the Mac partition I restarted the iMac to Windows 7. I did not eject and unplug the ext HD before restarting, not sure if it played into my problem or not but thought I’d mention.

Once Windows 7 started I opened up My Computer and I did not see the ext HD listed. I ran Disk Management and saw the ext HD listed but it did not show any partitions. Just shows the entire ext HD unallocated.

What do I need to do in order for Windows to see the necessary partition?

Been reading up on the different “options” for the partitions; i.e. GUID and MBR.

  1. Hovsep,

    I originally read that link you provided before I was having the issues. I solved the problem yesterday. I changed the Windows partition on the external HD to MS-DOS, ejected the HD, rebooted into Windows 7, plugged in the HD, Windows saw HD right away, went into Disk Management and changed the Windows partition from MS-DOS to NTSF.

    Thanks for everyone's help.

    • Thanks for your feedback:) your valuable solution will help others:)

  2. I am a bit surprised you are having issues because your iMac and OS X version suggests that the drive is most likely formatted using the GUID/GPT partition scheme which Windows 7 should have no issues with reading.

    It‘s just that simple. If you‘re not in love with what you bought, return it to zZounds within 45 days, and we‘ll promptly arrange for an exchange or a refund. Tascam us 1641 driver mac os x. We pull it all off with our strategically placed, coast-to-coast warehouses.4. ZZounds makes returns super easyBuy it, try it, like it, or return it to us for a full refund.

    Actually, being curious I just tested it with Lion and Windows 7 (no bootcamp):
    I partitioned a drive with one OS X Extended partition, one ExFAT using the GUID partition scheme and Windows detected the ExFAT partition right away.

    Maybe it's a derp from bootcamp? Anyway, the options you were reading up on are most likely the solution to your problem.

    Since you only used Time Machine so far and Windows couldn't even access the drive I assume you have no problem with formatting the drive again losing all data currently stored on it?

    Go into Disk Utility, select the external drive and click on the partition tab.
    Select 2 partitions etc. as you did before ~ OS X Extended for Time Machine, ExFAT or Free space for Windows. At the bottom click options and select 'Master Boot Record'. Then finally apply the settings and let the drive partition.

    Maybe bootcamp only likes MBR partitions ~ hope this solves your issue.

    • Not quite what I am asking.

      Bought the external HD because it is compatible with Mac and Windows because of the pre-installed Paragon driver (allowing Mac to read and write on NTSF). However, there was a note saying Time Machine wouldn't be able to be used. So I reformatted the external HD.

      I'm wanting to know why the partitioned disk is not showing up in My Computer. In Disk Management the entire external HD is unallocated. Only option when right clicking not grayed out is to format it.
