How do I format a FAT hard drive to MAC OS?

I have a RAID Windows 1TB hard drive that I would like to format to MAC OS Journaled. I try to do it through Disk Utility but it doesn't work.
Any suggestions?
Dwight

Good job with the log file, unfortunately it doesn't have any more detail about the error! Ugh. I would have expected at least a cryptic message such as "ABEND 0xEF32032". It appears to create the partition map successfully, that takes 15 seconds, but then fails 1 second into the formatting; if I have the time units correct.
This is beyond my knowledge. So the rest of this post is guessing or shooting in the dark. I suspect it has to do with RAID, which I have not yet used. And I have never used the RAID utility, whats that for? Isn't there something about Mac can't boot from raid? When I have formatted to OSX extended lately, DU automatically has stuck in EFI and Recovery partitions (if I remember correctly), I wonder if it is trying to do that. I'm using different versions of DU probably.
Do you have access to any other machines? You don't have to use a Mac, but your chance of success diminishes. Maybe (first aid, then) try formatting it to xFat or NTFS, [on the mac, or then bring it back to the mac,] change the partition scheme, apply, then add a second partition, making the first one (windows) as small as you can… Wait, according to your log file, the partition scheme is Master Boot Record, is that what you want?

  • How do I format a internal Hard Drive from a PC/laptop

    How do I format a internal Hard Drive from a PC/laptop...My old internal hard drive had problems so I took it out and I have a 100 gb Seagate ATA drive that I replaced it with. In the mean time I've been using a external drive to boot up my powerbook g4. Not sure of what to do.

    Hi, capitala1. Start your Powerbook up from your Mac OS X installer disc and open Disk Utility from the Installer or Utilities menu (depending on which OS version it is). Select the newly-installed Seagate drive inside your Powerbook as the target, and format it "Mac OS Extended (Journaled)". It makes no difference at all that the drive came out of a PC laptop: this is exactly the same procedure you'd use if the drive had just come brand new from its manufacturer.

    No chance without special tools/knowledge. There are companies that can do it, unless you use multiple format or rewrite data with special erase ustility or unless you have done low level format.

  • Can I format an IDE Hard Drive from Mac Pro?

    I use a mid - 2012 Mac Pro; run Mavericks OS X 10.9.2.
    1. Can an IDE hard drive (using an external drive) be formatted to 10.9.2, from my Mac Pro using Mavericks? (the IDE hard drive is new/unformatted).
    2. Once formatted to 10.9.2, can I reformat the IDE hard drive to Mac OS X Leopard 10.5.8, from my Mac Pro using Mavericks?
    3. If so, would should I do to accomplish Question # 2 above?

    The version of the OS that is running  is not relevant to formatting the drive. When you format a drive in any OS, you should select "Mac OS extended journaled." (That is, unless you plan to share the drive with a Windows computer.) Formatted this way, the drive can be used with any version of Mac OS.
    You do not have to reformat the drive each time you connect it with a different OS.

  • How can I format an external hard drive to Fat 32?

    My brother wants to connect an external hard drive to his Sony PS3 for backup purposes. He bought a Western Digital 3TB "MyBook for Mac".
    The PS3 requires the drive to be Fat 32 format. So I hooked the drive up to my new-ish iMac and went into the Disk Utility, selected "Partition", then said I wanted one partition.
    I named the drive "FAT32", selected "MS-DOS (FAT)" for the Format.
    HERE'S THE PROBLEM: when I go into the "options" menu in order to select "Master Boot Record", it is grayed out. One guy told me that it was because my computer was corrupted, but the same thing happens on my parents (older) iMac.
    Another person said it had to do with the fact that the drive was 3TB. Whu...?
    If anybody could help with this issue, I would be VERY grateful.

    Thank you AnaMusic... this is a nice resource for information.
    However I am still not sure I understand why I can't actually DO the partition/formatting. Any idea why the "Master Boot Record" is grayed out? That's the part that has me stymied. As far as I can tell I'm doing all of the required steps correctly.
    Again, thank you for your help.

  • How do I format a portable Hard drive for both mac and pc?

    I have searched and came up with this answer which doesnt make too much sense to me 
    ( Either format it to MS-DOS from the DIsk Utility, or install a tool such as MacDrive into Windows and keep the drive in its current format, or install the NTFS-3G driver into Mac OS X and format the drive to NTFS in Windows.)
    I have a La Cie rugged poerable HD  I want to copy media files from both my work Pc and my home mac to it, and then plug it into my TVIX machine ( windows based media player) to access the files.  In simple terms, how do i do this? 
    TIA Wayno

    Yes, FAT is limited to 4GB. You can use exFat which does not have such limitations and works both on windows and mac. You may also stay with ntfs but with additional software such as ntfs for mac osx. 9.0 by paragon software. Using paragon software will give both access to read on write files on your hard drive on while used on your mac.

  • Mac Pro: How do I format a new hard drive?

    Hello,
    About to open and install a new Samsung 3.5" SATA internal hard drive into slot 2. This drive will only be used for audio and I was told to format the drive in Mac OS Extended with journaling disabled and a single partition.
    I am not quite sure how to do this, and since I am already suffering from the frequent computer crashing firewire debacle, I want to make sure that I get this right.
    So, any advice before I start this next project would be extremely helpful. I simply can not afford any more problems.
    Thanks!

    Extended Hard Drive Preparation
    1. Open Disk Utility in your Utilities folder. If you need to reformat your startup volume, then you must boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger or Leopard.)
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
    3. Click on the Options button, set the partition scheme to GUID (only required for Intel Macs) then click on the OK button. Set the number of partitions from the dropdown menu (use 1 partition unless you wish to make more.) Set the format type to Mac OS Extended. Click on the Partition button and wait until the volume(s) mount on the Desktop.
    4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
    5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
    6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
    Steps 4-6 are optional but should be used on a drive that has never been formatted before, if the format type is not Mac OS Extended, if the partition scheme has been changed, or if a different operating system (not OS X) has been installed on the drive.

  • How do i format a external hard drive?

    i got a external hard drive to use as a back out. but i have no idea how to format the external HD. what should i do? how?
    thank u

    connect the hard drive to the mac
    run disk utility (found in the applications/utilities directory)
    the drive should be displayed in the lefthand pane of the disk utility window, click on it to select it
    click the 'partition' tab, it should show the current format and allow you to alter it if necessary, for mac use the "mac os extended (journalled)" format
    once you've formatted and/or partitoned the drive it is a good idea to go to the 'erase' tab and use it to write zeros to the disk
