"Format USB drive to single FAT partition"

I'm trying to use Boot Camp to install Windows 8 on my Macbook Pro, but when I was going to save the Windows support software to my external hard drive I'm told to "format the USB drive to single FAT partition."  I thought I had done that, but after I used the same hard drive to back up my computer, it seems that it went back to its original format.  Does the hard drive have to be empty to download the support software, or did something else go wrong?

try formatting with ExFat, it'll detect immediately.

    Drive Partition and Format
    1. Open Disk Utility in your Utilities folder.
    2. After DU loads select the USB drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
    3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to MBR then click on the OK button. Set the format type to MSDOS. Click on the Apply button and wait until the process has completed.

  • "This USB drive cannot be used. Please format the USB drive as single FAT partition."

    I only have one external drive..can I use it both for time machine AND saving windows support for bootcamp?
    I partitioned my external drive into two: one for Time Machine backup, and the other as MS-DOS FAT.
    But this won't work when I use the BootCamp Assistant. What should I do? I don't want to reformat my external drive and not have a backup of my Mac, and I need to install PC-only software for class.

  • Can a AP Extreme host a USB drive with one FAT partition and one MacOS?

    Hi guys,
    Hopefully a simple question that I didn't see a clear-cut answer to in the archives: can a USB drive, being hosted from an AirPort Extreme, have both a FAT partition and a MacOS Extended partition?
    Thanks!

    What is a "Single FAT Partition"?

    This is your third post, in the first one I strongly suggested that you read the Boot Camp directions, it appears that you have not.
    So I repeat my advice, read the directions before you bork your Mac.

  • IMac and Formatting USB Drive Issues

    I have an 8GB USB drive that I formatted to MS-DOS FAT using my iMac with 10.6.4 on it. However I now realise that that was a stupid thing to do as now that drive no longer works on Windows no matter what I format it too. I want the pen to allow me to use it on both WIndows and Mac (hence the FAT format) however Windows sees the drive as an unformatted 200MB drive with 7.16GB of unallocated and corrupted space which cannot be formatted.
    Windows cannot even attempt to allow me to format it to gain the 8GB back as it is unable to format the space even when its turned into free (empty) space. Luckily OSx can still use it as normal but it just means I've lost a perfectly work USB drive due to an error in OSx.
    Can anyone help to to fix this as I really want it to work and I'm stumped as to how.
    Thanks!

    It shouldn't matter as I created the files and folders originally on a FAT formatted drive and copied them to my Mac then back at a later date, at which point an error was encountered and prevented me copying folders to the dive (the contents was fine once removed from folders and sub folders).
    I believe Apple has fixed this now, however when I formatted the drive my iMac had this problem so I believe this effected the FAT formatted drive to prevent Windows working with it.
    Well I have finally managed to fix the drive. I had to format the drive to free space and then plug it into a Windows 7 PC and then delete the free partition and reallocate it again to FAT 32. Window Vista and XP where an able to do this as they say I didn't have permission to do this and asked for a restart. Strange but atleast it finally works on both machines.

  • Install Windows 7 on new MBPr from FAT32 formatted USB drive

    My colleague gave me a USB drive with legit Windows 7 Enterprise SP1 64bit as ISO file on it (plus a folder containing Windows software to be installed afterwards.
    I have partitioned the MBPr's SSD 50/50 with disk utility: one OSX partition, one MS-DOS FAT32.
    When I reboot and select the USB drive to install, I get a black screen with a message on top "booting from Boot Camp Assistant created USB drive ... Failed to load BOOTMGR".
    This happens trying both left and right USB ports.
    Reason why I partitioned 50/50 "manually" with disk utility was that Boot Camp-Assistant did not give me an option to install from the USB after it downloaded drivers to that USB (these drivers ended up in a folder called WindowsSupport). It always asked me to insert a DVD which of course can't work on the MBPr.
    Any hints much appreciated!

    You must use Bootcamp Assistant to install Windows in a Bootcamp partition. Return your hard drive to a single OSx partition then start again following the Bootcamp Installation and Help guides.

  • Mounting a UFS formated USB drive on Solaris 10

    [Hope this is the correct place to post this question]
    I connected my 160 GB external usb hard drive to my V240 Solaris 9 server, ran newfs (ufs), mounted it, and wrote data to the drive with no problems.
    I moved it to another sparc box with Solaris 10 (build 74-1) and tried mounting it, but no luck. The logical path for the usb drive shows up in "/dev/dsk" after running "devfsadm -C" and it shows up as configured when running "cfgadm -al," however, when I try to mount the drive it eventually times out without mounting. I get the same results when I try this on the x86 version of Solaris 10.
    I know that the drive still works by taking it back to my Solaris 9 server and mounting the drive.
    Is there something special or different with mounting usb drives with Solaris 10?
    Thanks,
    Phillip

    It should be the same. For instance with a usb keychain (formated pcfs):
    mkdir /usbdrive
    mount -F pcfs /dev/dsk/c3t0d0p1 /usbdrive
    On this particular laptop the second usb port was. c4t0d0p1 so:
    mount -F pcfs /dev/dsk/c4t0d0p1 /usbdrive
    The numbering might be different for each usb port and you have to specify the filesystem of the usb drive, but it should work.

  • Reformating a 3 GB USB drive into just one partition

    I once tried to plug a 3TB hard drive into my 2008 iMac to discover it wouldn't recognize anything over 2TB. So, I upgraded to 10.8.5.  But evidently, when I originally tried to format the drive, I accidentally created 2 partitions.  When I plug the device in, I now have "2 hard drives" - one 2.2 TB and one about 800 GB.  I want to reformat these "two" drives into one usable 3TB drive.
    Any suggestions?

    Niel,
    The problem is, I'm not sure how to do that.  When I turn on the drive, it appears as "Untitled" and "Untitled 1" - as though they were two drives.
    When Disk Utility recognizes them, they are listed as such with the respective size of the partitions (801.57 GB & 2.2 TB) above them in the list.
    When I highlight one of the partition sizes (say, the 801.57 one), I DO now see the Partition tab.  However, I don't see where I can merely "delete" it.  It tells me that to erase and partition the selected disk, I must choose a layout from the Partition Layout pop-up menu.
    There is also an option to "drag" one corner of the partition layout to where it's only 53.59 GB, changing, but not completely erasing the partition.
    What am I missing here?

  • Mounting USB Drive in Single user mode

    My Intel Imac fails to boot up. fsck -y fails too ... can't think of any other way to get my data out ...
    I am left with the only option to copy my data into my usb drive in the terminal mode .
    But I am unable to mount my USB drive. I also need to know the mount point. can anyone provide me with help.

    The mountpoint can be anything you want. The tricky part is figuring out the device your drive is using. I don't know for sure (can't test it right now), but dmesg or one of the system logs might have that information in it if you boot to SUM with the external drive attached. The logs also might have a record of what device this drive used in the past when connected. It will likely use the same device every time.
    If not, you can guess. I have seen one of my external disks mount using the device disk1s2. If I were to attach that to my machine in SUM, I could then mount it like this:
    mount_hfs /dev/disk1s2 /Volumes/recover
    where the mount point /Volumes/recover is something I created (i.e. just a simple "mkdir /Volumes/recover"). This could be anything you want.

  • Formatting usb drives?

    Hello Everyone.
    I hope someone can help me out with this issue i am having. I wanted to format my usb hard drive, something that can be done easily in windows but i don't know how to do it on my mac. I have tiger on it right now.
    Thanks.

    Open Applications/ Utilities, launch Disk Utility, select the external drive, click partition tab, select a partition scheme, adjust partition sizes to suit your needs, optionally give the partitions descriptive names, click Options button and select format (GUID if you ant to be able to boot an Intel Mac from the drive, Apple Data Partition to boot from a PPC Mac), select format as Mac OS Extended or Mac OS Extended (Journaled), click Partition button.

  • Format Hard Drive in Single User Mode

    Hi All-
    I'm having some issues with my MacBook with a bad B-Tree. I've read a lot about how to use DiskWarrior to repair it. I'm not really interested in recovering my data, but I would like to install OS X.
    Those who've had a catalog issue or B-tree issue knows that fsck doesn't repair it.
    I'm having an issue with the Disk Utility on the start up disk. It's having trouble reading the disk and hangs at "Gathering disk information". I would like to boot into single user more and repartition the disk, I just don't know how.
    I have not had any success in finding my answer on the web, and am hoping that you can help out.
    Thanks!

    John,
    Disk Utility is also available at the command line. Open Terminal and type:
    <pre style="overflow:auto; font-family: 'Monaco'; font-size: 10px">man diskutil</pre>
    then press <RETURN> to view the man pages. I suggest that you give those man pages a good read, then come back here if you have further questions. If you cannot get to the man pages (if you don't have a working installation of OS X), I could give you a specific command to run, but I'll need to know absolutely everything about what results you want (just "repartition" is WAY too vague).
    Also, you might want to give Disk Utility another try, and give it plenty of time to handle the broken file system. Sometimes, a broken file system will become available for formatting, but only after an extended period of time (several minutes to an hour).

  • Disk Utility 13 problem with USB drives

    There appears to be a problem with Disk Utility 13 (part of OS X 10.9). At least, so far as I can tell, everything traces back to this app, or possibly OS X 10.9 itself.
    I recently upgraded my MacBook Air to OS X 10.9 (reformatted hard drive, installed system from scratch, updated with all the latest Apple updates). I pre-checked all my third party software to make sure it was 10.9 compatible before installing it after the system cleanup, so everything I’m running supposedly has been approved as safe for 10.9. But I’m seeing a problem formatting USB drives that I do not encounter when running under 10.8.
    I have a Seagate STAA500101 (“FreeAgent GoFlex”) drive connected via Seagate’s USB3 adapter that I’ve used for some time as a Time Machine backup. Post-overhaul, I decided to erase the backup and start fresh. When I attempt to format it (single GUID partition) with Disk Utility, I see the following messages go by:
    Formatting disk1s2 as Mac OS Extended (Journaled) with name Untitled 1
    Could not mount disk1s2 with name (null) after erase
    Then there’s a pause, and the format appears to conclude fine. But if I run a “Verify Disk” immediately, I get this:
    Verifying partition map for “Seagate FreeAgent GoFlex Media”
    Checking prerequisites
    Checking the partition list
    Checking for an EFI system partition
    Checking the EFI system partition’s size
    Checking the EFI system partition’s file system
    Checking all HFS data partition loader spaces
    Volume  on disk1s2 has 0 bytes of trailing loader space and it needs 134217728 bytes
    Problems were found with the partition map which might prevent booting
    Error: Partition map needs repair because a data partition needs loader space.
    As the drive has just been formatted, that seemed odd. I took it over to another Mac still running 10.8.5 and formatted it there — it worked just fine. Verified just fine. Took the drive back to my MacBook Air and tried to verify the disk — same failure.
    I wanted to rule out bad media, so I took a Lexar 16GB USB flash drive and tried to format it with Disk Utility 13 — got the same problem.
    The only success I’ve had formatting USB drives under 10.9 is to boot up into OS X Recovery. Disk Utility there formatted my Seagate drive without an error. But once I booted back into normal 10.9 operating mode, the drive once again fails to verify; it makes me leery about using it as a Time Machine backup.
    I suppose it’s possible there could be some background component like Sophos causing problems when formatting drives, but if I format a drive via OS X Recovery or another Mac under 10.8, that wouldn’t explain why the drives fail to verify.
    Anyone got any other observations on this issue?

    Problem resolved. I'm posting this note for anyone else who might run into this situation and come across this discussion.
    It actually did turn out to be Sophos -- Cloud, that is. I'd been using Sophos' free Mac antivirus software on a variety of systems but forgot that I was now testing out Sophos Cloud on my own MacBook, which is their new endpoint solution, and supposed to be compatible with OS X 10.9 (although the Mac version is listed as "beta") Sophos Cloud includes a new feature called Device Control which allows you to create a company-wide policy to control access to hardware such as USB drives, optical drives, etc. But apparently it's still pretty buggy. I had my Device Control configured with the default setting of "monitor but do not block" but it was most definitely gumming up the system. With Sophos Cloud installed, here's what happens if I try to run "Verify Disk" on any attached drive. Note on the left side how "disk2s2" shows as a sub-volume for each hard drive.
    So if I uninstall Sophos Cloud, reboot and rescan, here's what I get:
    Works fine. Note that the "disk2s2" subvolumes are also gone. This is the way Disk Utility also appears on a 10.8 or 10.9 system, even if you have the standard free Sophos for Mac software installed. It's only Sophos Cloud that's not playing nice. It also appears to have stopped me from being able to play DVDs from an attached Apple USB SuperDrive -- that problem was likewise solved by removing Sophos Cloud.
