  I guess that the external hard drive is formatted NTFS, so disk utility does not have to perform all the tasks in this topic. It you can't format it on some Windows system with the FAT file system? Once the FAT is made, the Mac of THE it reformats with HFS. However if you want to do with the above partition size (1 TB HFS and 1 TB NTFS or FAT) then can try you with a disk management utility.

• How partition an external hard drive and configure for Time Machine backup?

  I am a rookie just to switch to Windows Apple Mac and I'm looking to back up my new iMac with a Seagate hard drive 2 TB external.  My Mac is a 1 TB hard drive, I'm looking to partition for backup and storage.  Is this a good idea?  Is there a simple way to do it?  I appreciate any help I can get.  I also bought three years of Apple support, but I'd rather do it myself, so I thought I'd give this discussion from the community to try.  Thank you!!

  No, it isn't. Your working data and backups must be on separate drives in case one of them goes down.

• Can not resize the partition to external hard drive

  I have a LaCie D2 Quadra 1 TB external drive that I used occasionally since 2009. Way back when I partitioned into two parts, the two put in place under Mac OS X extended (journaled). I put one in 867 ~ GB and the smallest to 133 ~ GB. The smallest one I use for a bootable backup.

  I want to increase the size of the bootable part. DiskUtility looks that would, without erasing any data. But even once I selected for the largest part smallen (without going into the blue "in use" section) I can't always increase the size of the bootable. The grabber resizer indicator seems pointless because it won't pull up. (It's in the lower corner of R).

  I made sure property allows me to read and write on both partitions.

  I will be grateful for a solution.

• Creating Installer bootcamp on the external hard drive instead of the USB partition?

  Hello

  I have a MacBook Pro 2012 and mountain LIon. I want to install Windows 7 via bootcamp, but my USB isn't enough grand (only 4 GB of free space). Instead, I expect to use my external hard drive. However when I go to bootcamp to create the installation program, it gives a warning that my hard drive will be erased. It is not possible to create the installer on a partition instead of him wiping the entire HARD drive?

  Thanks for the help!

• external hard drive partition copy

  I have an external hard addrtiion to my computer.  I have a disc managerment that allows me to copy partitions.  If I copy the partion on my internal hard drive and stick it in my outside, is that I gave two fully functional WIndows XP now. If Windows crashes I'll be able to start on the external hard drive?

  And even ewrase and reformat the drive internal and copy the my external hard drive4 patition.   Indeed, never lose Winows XP and all my programs installed again?   Or is it simply a desire that can really be achieved.

  Your program has the ability to create a partition bootable (what is the name of the program)?
  If your program has the ability to clone, then this is the way to go if you want just an exact replacement for your internal drive, if a problem occurs catastrophic. A better option would be an imaging program that allows you to create images of your internal drive like this at some point. In this way, if you have a regular image, say twice a month, so you can fit maybe three or four images on the same drive that you want to clone in. A cloned disk must be the same size or larger that the drive is cloned. An image is compressed and takes less space.

• The external hard drive partitioning

  Can Hello: Anyone help me with a beginner?

  I have a 3 to external hard drive that I want to score in three volumes of 1 TB. But every time I try to use DiskPart it divides the first partition in a 2 TB and from there I can not extend it. When I cut it up to 1 TB it gives me two volumes, K and L, but then I can't expand the volume of L. It's all leaving me with 746 GB unallocated I can't use.  Is in anyway possible of this Dove upward from the way I want?

  You must convert the GPT disk. Delete all partitions, right-click on the gray area on the left and select "convert to GPT disk.

• Using a Mac to partition a USB external hard drive to use to start Windows 7 on a PC

  Hello

  My PC hard drive died recently, and I need to reinstall Windows 7. Fortunately, I have a Windows 7 .iso file on my Macbook Pro. I also have an external hard drive USB empty. I try to use the Mac (in particular the disk utility program) partition this hard drive and load the .iso file in it, with the intention to start the system and install Windows 7 on my PC. (NB. I have a new internal hard drive which I intend to install Windows on to, but it's something that I should be able to handle later and should not be relevant at the moment.)

  As my DVD player also decided to break (I had not used for a long time), I can't burn the .iso to disk image file and start that way.

  So my question is, what is actually in all possible ways to use my WD 500 GB external hard drive to boot Windows 7 from USB? If so, is it possible to configure the hard disk with the .iso image file using a mac? I think I need somehow do "bootable" my hard drive to boot from it, but I don't know how to do this using a mac, so that it will be compatible for Windows startup.

  I've had this problem for days now and nothing I try seems to work - I tried what seems like all combinations of formatting, partitioning, extracting, BIOS-set-up-ing and file-system-change I can think of. Any help will be really appreciated. Also, if you need information such as specifications, just let me know and I will try to provide all the details I can.

  In addition, I understand that there a lot of messages on the boot from external hard drives, but I looked carefully and found nothing for my situation (more precisely using a mac).

  Thanks in advance for help; If all goes well there is something obvious that I'm missing that I can fix it easily.

  Hi Michael,

  Thanks for posting your query in Microsoft Community.

  From your problem description, I understand you want to make bootable Windows 7 disk using Mac computer.

  About a tool to burn an iso image on Mac, I suggest you contact apple support.

  https://discussions.Apple.com/community/desktop_computers

  However, as a solution, I suggest to go to one of your friend who has the operating system windows download Windows 7 USB/DVD download tool and burn the iso image.

  Detailed suggestions are mentioned in the following article:

  I hope this helps. If the problem persists or all linked windows queries or issues related to the Windows operating system, please get back to us. We are here to help you.

• external hard drive partition removal

  WD external hard drive has bought recently.  He had a factory partion and I can't remove it.  Disk management I tried and do me not (as an administrator) to remove it.  I can change the drive letter, but not anymore.  It shows up as a CD drive. but this is not a cd.  I have not installed the factory program that came with the disk that is on this partition (665 mb).  Rather I copied information from the computer to the disk manually (I know not so old school).  I want the missing drive, but have failed so far.  Probably should have formatted drive until I copied the data on it, but too late now (it took 8 hours to copy all the data).

  Help?

  Hello foxman24,

  The partition you make reference to contains the WD SmartWare software. So you can successfully unlock your drive on each computer that you connect to. If you do not use SmartWare and do not want this virtual CD you can disable it by following these instructions: http://products.wdc.com/support/kb.ashx?id=YJvBcl
  Hope that helps.
