Formatting using Disk Utility

i have a USB drive of 8 GB (pendrive) currently formatted in FAT-32, i would like to know
(a) How to format it into MAC OS JOURNALED ?
(b) Will formatting it into MAC OS Journaled make it non-readable on WINDOWS PLATFORM?
(c) And after formatting in into MAC OS JOURNALED can i again format it back into FAT-32 system without corrupting the USB drive ?

How to format it into MAC OS JOURNALED ?
Open the Disk Utility in the /Applications/Utilities/ folder, select it in the list on the left, and use the Erase tab.
Will formatting it into MAC OS Journaled make it non-readable on WINDOWS PLATFORM?
Yes, unless the PC has third-party software installed which provides access.
And after formatting in into MAC OS JOURNALED can i again format it back into FAT-32 system without corrupting the USB drive ?
Yes.

  • I need help with boot camp. "Back up the disk and use Disk Utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again."

    This message appears every time I try to partition my disk:
    "Back up the disk and use Disk Utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again."
    I verified my Macintosh HD disk on Disk utility and then tried to repair it, but I am unable to click the repair button.
    It says it's not available because the startup disk is selected.
    I don't know what to do or how to go about both these problems.
    Please, any suggestions?

  • Both my MacBook Pro Retina Display and new iMac will only format an SD as FAT16 using Disk Utility.  How do I format in FAT32

    I have a new iMac and MacBook Pro with Retina Display running 10.8.2
    When I use Disk Utility on a San Disk 2GB SD card I can only format as FAT16.  How can I format the card as FAT32?

    Just posted a problem I'm having connecting my Jaybird Freedom and iPhone5 (https://discussions.apple.com/thread/4716045). The Jaybirds connected fine with an iPhone4s and another (forgotten) device so I don't think the problem lies with the Jaybird. I'd be interested if you hear differently.

  • Format a 3TB HD using Disk Utility with Yosemite?

    Can a 2014 Macbook Pro running Yosemite format a 3TB HD intended for an external case using disk utility? I've had issues in the past with a 2010 Macbook Pro and am hoping its now not an issue.

    There should be no problem.  There might be a problem if the given HDD has some proprietary software installed by the manufacturer.
    Ciao.

  • Formatting 2GB SD card with FAT32 using Disk Utility

    Hello
    I'm trying to format a 2GB SD card in a card reader/writer to FAT32 using Disk Utility. Unfortunately the only option available under the Erase button is "MS-DOS File System (FAT16)". I need to do this to upgrade the firmware in my Sony TV which requires a FAT32 formatted USB device.
    Any help or suggestions would be greatly appreciated.
    Thanks
    Tim
    P.S. Unfortunately I'm stuck in OSX Tiger on an old B&W G3 while my G5 undergoes repairs.

    Ok, well anyone know of a free OSX 3rd party utility that will enable me to format the SD card to FAT32?
    Unfortunately I don't have a larger SD card.
    I tried my 1GB SD card on a XP PC and I'm not given the option of FAT32. So it may be a limitation of the SD specification, which means you may just need to bite the bullet and buy a larger SD card.
    Perhaps you can ask Sony if there's some setting on your device to use something other than a FAT32 SD card. (I mean, this is Sony after all, you'd think they'd prefer Memorystick. )

  • I am now using 10.6.8.  Downloaded Maverick but cannot update OS on HD because get message the disk is not formatted as Mac OS extended(journaled).  Tried to use Disk Utility as per instruction but cannot complete operation.

    Barney-15E:
                   The partition method worked after some trepidation.  I got the spinning beach ball after partitioning and couldn't go further till I named the second partition.  That may have done it.  Right now, things seem to be working o.k.  I'm updating a current iPhoto and will have to get a MS Word program that will function on the current OS and a current  Quicken.
    If necessary, can start up from the 10.6.8 system which I downloaded to an external HD before updating.  I can always fall back on that.  Also, I hope I don't get too many disconnects.  Thank you for your help.

  • Formatting external storage device using disk utility

    how do i format my external hard drive using disk utility? thanx

    I just went to DU and looked at Help to be sure the instructions were clear.
    Go to DU, then go to Help. I put in "formatting HD" in the ask a question field and quickly got the directions for how to do this. It depends on whether you are wanting to format a startup or non-startup disk and whether or not you want to partition the drive. You aren't specific in your question here - sorry for being rather vague in my reply.

  • Using Disk Utility to format jump drives to work on a PC?

    I have tried several times to format usb jump drives using Disk Utility and then I copy files to it and try to open it on a Windows computer and it prompts me that it needs to be formatted on the Windows computer. How do I format it on a Mac to work on a PC? I have tried this with different usb drives using the MS DOS format option.
    Thanks.

    Dude,
    Of course this isn't a jumpdrive but for externals...
    There's a bug in Apple's disk utility software when using USB. I just had this happen to me too. The work around is to use Firewire when formatting. Fortunately, I have a multi port interface so changing to Firewire wasn't an issue.

  • Cannot format iPod using Disk Utility

    My iPod (5th Generation) has been displaying a -48 error for weeks, and i tried to follow the advice to format my iPod using Disk Utility. However, after leaving my iBook 1.2Ghz G4 on over night with Disk Utility erasing it, the little bar was still stuck on partitioning, never moving. What can i do?

    try reset in iTunes. Then follow the steps in Jason Creasey's excellent procedure in the long thread ref Code -48. Good luck.

  • The difference between a .dmg file & a .cdr file (using Disk Utility) ?

    Hi,
    In particular, I created both from a DVD using Disk Utility.
    When I chose "read only" a .dmg was created.
    When I chose "DVD/CD Master" a .cdr was created.
    They are exactly the same size.
    Is there any difference ?
    Thanks in advance.
    Pat De Marco

    HI Pat,
    From Wikipedia: A file with the extension .dmg (an abbreviation for disk image) uses a disk image format commonly found on Mac OS X. The format allows secure password protection as well as file compression and hence serves both security and file distribution functions. Its most common function is the distribution of software over the Internet. When opened, DMG files are "mounted" as a drive within the Finder.
    From: Wikipedia .cdr and ISO
    ISO image
    Filename extension .iso
    Uniform Type Identifier public.iso-image
    Type of format Disk image
    Standard(s) ISO 9660
    An ISO image is an archive file (a.k.a. disk image) of an optical disc using a conventional ISO (International Organization for Standardization) format that is supported by many software vendors. ISO image files typically have a file extension of .ISO but Mac OS X ISO images often have the extension .CDR. The name "ISO" is taken from the ISO 9660 file system used with CD-ROM media, but an ISO image can also contain UDF file system because UDF is backward-compatible to ISO 9660.

  • Ipod Classic Re-Formatted In Disk Utility Not Being Recognized

    I last posted about this question 4 months ago on this forum and still havent received an answer that works. My Silver Ipod Classic 80GB was used to update the OS on my computer. Foolishly I partitioned the disk on it using disk utility and updated my computer. After i tried to erase the partition the ipod stopped being recognized as an ipod on my mac running OSX. It is recognized as a hard drive. I formatted it with Mac OSX extended Journaled in disk utility and nothing seems to work. When i plug it in itunes auto starts and pops up but the Ipod simply doesnt show up in the side bar. I have tried it on all different macs and windows computers and it still wont be recgonized on the mac. On the windows machine i am able to reformatt it so it works with a PC but when i plug it into a mac itunes autostarts and it still isnt recognized as an ipod
    help would be greatly appreciated

    i dono man, but I have exactly the same prob. if u wouldn't mind letting me know if you figure it out I will be happy to send u a quick message if I figure it out first
    thanks

  • When I check my boot SSD drive using Disk Utility under Mavericks, I often get "Incorrect number of extended attributes" errors.  But if I boot off an external drive and check the same SSD, no errors are reported.  Is this a bug in Mavericks?

    When I check my boot SSD drive using Disk Utility under Mavericks, I often get "Incorrect number of extended attributes" errors.  But if I boot off an external drive and check the same SSD, no errors are reported. 
    This happens not just with the SSD in my Mac Mini, but with another SSD in my MacBook (both now running Mavericks).  So far as I know, all of the kit I am using is in good order (despite the file corruption reports).  So I am beginning to wonder if it could be due to a bug in Mavericks?  Both SSD drives have been formatted to MacOS Extended (journaled) format.  Should I have used a different format, I wonder?
    Has anyone else encountered this issue?
    Does anyone have a solution?
    Or an explanation that might help my investigation of the issue?
    Thanks guys,

    I understand that the Corsair Force 3 is not one of the SSD drives that are supported on Apple Macs. 
    I did try downloading and using Trim Enabler, but the error message came up both when it was off and when it was on.
    I understand that not everyone thinks Trim Enabler is a good program, though there is a new version out now, so I may give it another try.

  • Using Disk Utility for Boot Camp to work

    I'm trying to install Windows 7, but Boot Camp gave me the old error message about having unmovable data and needed to use Disk Utility to format it as a Single Mac OS Extended (Journaled) Volume. So I backed everything up and am ready to go, but when I open Disk Utility and select my hard drive/disk, all the options under "erase" are grayed out. Any ideas?
    Thanks!

    You can't format what you are using.
    If you cloned your drive you would be able to boot from that; if you used another method and you don't have OS X installed on another hard drive, you have to use your DVD.

  • Change the partition of an external drive using Disk Utility?

    I wish to change partition scheme, sizes, in an external drive. All the partitions are MacOS extended (Journaled) and they map, according to the layout in Disk Utility, as follows: Partion 1, 2, 3,4 where 1 is at the top and 4, the bottom. I want to make partition 2 larger, so I decreased partition 1 by half. Now the layout is 1 a, 1b, 2,3,4., where 1b is now free space. Disk Utility will not allow me to increase the size of  partition 2 by dragging the corner. Which of the following options (if any) will allow me to increase the size of partition 2, without erasing the data, using Disk Utility:
    Select partition 2 and manually writing a new value in the size box, equal to the present partition’s size plus the free space?
    If I delete partition 1 completely, will I then be able to increase the size of partition 2?
    If I delete partitions 1, 3, and 4, will I then be allowed to increase the size of partion 2?
    Is there another option?
    Thanks
    (Actually, partition 3 is an eDrive, a data recovery utility created by TechTool Pro 7, so I don’t really know how it’s formatted.)

    You cannot re-size the existing partitions in such a way that you can take the space from a shrunken partition and add it to another partition. Disk Utility cannot do that. If you have an existing partition that lives above another partition, then you can delete the lower partition in order to expand the upper partition into the freed up space. This concept applies to any additional partitions that are below another partition. Disk Utility can do this. You can resize down, but not up, except when creating new partitions. You would need third-party software such as iPartition 3.4.3 to accomplish that feat.
