USB stick formatting

I bought a Verbatim USB stick (1GB) that has stopped working. None of my three Macs can see it anymore. I tried plugging it into my windows machine at work and it 'sees' the stick, but cannot open it. Is there anything I can do other than give up?

You might try just waiting a really long time to see if it eventually shows up. A USB flash drive needs to be "ejected" before unplugging it. Maybe it was pulled out of the device without being properly put away, and it's behaving like an external drive that's been improperly removed? Sometimes it can take 10 minutes for them to eventually show up again.

  • USB stick and FAT formatting

    My USB stick stopped working on normal PCs.
    First i thought that It's broken but I've figured out that it works on my mac.
    So I don't know what to do to make it visible by a PC.
    I formatted it more than 5 times already and nothing. I even erased all data and all the stuff.
    And I picked the FAT option. So I don't know what seems to be the problem. :S

    I've had problems on more than one occasion with a USB stick formatted as FAT on the Mac, where it works fine, but isn't recognized by Windows. What I've done is just reformat it on the Windows machine. After that the sticks have worked fine on both Windows and the Mac.

  • Windows 7 doesn't release USB stick - can't safely remove USB stick

    Sometimes when I'm trying to safely remove an USB stick formatted with NTFS from any Windows 7 installation, Windows 7 refuses to release the USB device.
    This occurs on host machines as well as on VM guest machines. When I'm attaching the USB stick to a virtual machine (VMware Workstation) and when this effect occurs in there I can see from Workstation's device manager that the USB stick is getting accessed
    once every (approx.) five seconds. The USB stick shortly flashes up accordingly then, so there is indeed some access to the USB stick.
    Now, this doesn't happen all the time. This effect only occurs, say once or twice a week.
    Waiting for 5 to 10 Minutes, the low-frequent regular short flashing finally stops and I can safely remove my USB stick then.
    Well, what I want to know: Which Windows service is sometimes accessing my USB stick in this manner?
    This happens on several machines, some of them having almost no software installed.
    When exploring the file handles with SysInternals Process Explorer, there's only a Windows Explorer handle attached to the USB device.
    I suspect it might either be Windows Defender (having Search Removable Devices enabled), Windows Search or Windows Defragment. But this is only a guess.
    Can anyone please enlighten me on which service is capturing my USB device for such a long time, keeping me from safely removing the USB device?

    Mel,  Sure, although that is "copying," not "burning."  It is easily done, as follows:
    Insert the USB stick into your computer, and open it up so it looks like a folder.  Highlight the songs you want in iTunes, and drag them into the folder.
    If you normally run iTunes in full screen mode, make it smaller so that you can do the drag.

  • Time machine backup of Mac-formatted USB stick impossible in Lion?

    Hello. Since Lion, Time Machine refuses to backup my USB sticks. In Options, they appear as excluded from backups. I can take them off that exclusion list and hit Save, yet when I reopen Options, they are back on it and still excluded. I even erased and re-formatted them (Mac OS Extended (Journaled)), no change. (The USB Sticks are: 4.04 GB LaCie itsaKey Media; 4,04 GB Generic Flash Disk Media.)
    All this applies to USB Sticks only, not to USB external volumes. These are excludable and integratable as expected. 
    I can't imagine backing up USB sticks is now generally impossible; would anyone have any idea what might cause this problem?
    Thanks, best

    Yep, trying to include the extra storage disk in the TM backup. I realize I can connect the disk to a backedup Mac as a quick fix, but need the extra storage disk to remain an airdisk for remote access, independent of my computer.
    So, I'm guessing there is no way to include it as long as it's sharing a spot on the AEBS's USB hub?

  • How do I format a USB stick on my iMac

    I am a recent mover to OSX and need to reformat a simple usb stick. I tried finder and could not figure it out.

    Drive Preparation
    1. Open Disk Utility in your Utilities folder.
    2. After DU loads select your hard 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 GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
    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 Security 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.

  • Unable to format usb stick all options in erase are grayed out

    Iam having a problem with a 2 week old emtec 128gb usb stick, it is stuck on read only. 
    I bought it because i recently bought a new macbook pro 2013 and i needed a drive that worked on both mac and windows to transfer mostley media files from my old hp to the mac.
    It worked fine the fist couple of times i used it, copying/pasting files between windows and mac, and then i connected it to my gf macbook to copy some files but i couldnt because it had changed to read only. I connected back to my macbook to change it in the get info but there was no option to change it on the bottom in the sharing & permissions it just has "you can only read". I connected back to my gf macbook and tryed the same thing but that didnt work eirther. I then tried to repair the stick in disk utility but i only had the option to verify and that told me to repair it but the repair button it gryed out, so i then tryed to re-format it but all the options in the erase part are gryed out.
    I have also tryed to format it on a pc but that didnt work it say it is "write protected". There is no physical switch on the stick itself that makes it read only. The sticks format is fat32.
    So my question is, does anyone know of this happening before and if so did they find a solution??

    So emtec had a restore tool for that modle usb stick, they sent me this download http://www.emtec-international.com/sites/default/files/drivers/restore.ziip
    This fixed it, even tho i stated i own a mac in the email i sent to emtec this restore program will ONLY work on windows

  • Formatting usb-sticks on iMac - Snow Leopard

    I have two USB-sticks, which I used several times, all files have been deleted.
    Nevertheless they show as being nearly full, so I cannot save anything else on them. Is there a possibility to format these sticks, so that the space is available again? Or do I just have to through them away?
    An answer (if possible step-by-step) would be very much appreciated.
    An amateur from Vienna

    Hi and welcome to Discussions,
    when deleting files from an USB-Stcick you should not forget to empty the trash afterwards and before disconnecting the stick.
    Otherwise the files you deleted are still eating up the space on the stick.
    For formatting an USB-stick you can use Disk Utility (might be Festplatten-Dienstprogramm in Austria) to be found in the Applications/Utilities Folder.
    In Disk Utility click on the USB-Stick in the left pane, then on the Format-Tab in the right pane.
    Use the Disk Utility Help function if needed.
    My I also suggest to have a look at these informations

  • EXFAT formatted USB stick - sharing permissions wrong - Read Only - Cannot Reformat - Help please!

    EXFAT formatted USB stick - sharing permissions wrong - Read Only - Cannot Reformat - Help please!
    Hi.
    Having various problems with a USB stick that is formatted in EX-FAT.
    It was working fine for a long period.
    Yesterday I lent it to a friend to put some things on it.
    Now when I try and work on it, I get messages like this.
    Mac OS X can’t repair the disk “Disk Name"
    You can still open or copy files on the disk, but you can’t save changes to files on the disk. Back up the disk and reformat it as soon as you can.
    It will also randomly eject the drive.
    I have tried to reformat it multiple times, in mac and windows.
    [I have never used it in windows previous to this occasion of needing to reformat].
    In windows, it crashes the disk when I attempt to format with disk manager [I attempted this due to advice in an internet article].
    In Mac , I cannot even try to reformat it, because for some reason the permissions on the USB stick have been set to "read only" and I cannot find any way to change them to read-write, or full permissions, or whatever is appropriate.
    I have tried "erase" disk in disk utility. I know how to do a full reformat, but it simply will not allow me to do so.
    All the options are greyed out.
    Does anybody have any information or links they can point me to?
    I've been searching around.
    Thanks very much in advance for any advice received.
    Running latest mountain lion , 10.8.4, and windows 7 through VMware fusion.

    Start over:
    select the drive > select the Partition tab > select 1 Partition
    select Option > select GUID Partition Table > select OK
    name it > click the Apply button > then lastly click Partition

  • Making a Windows 7 Installation USB Stick

    This is a discussion of making a bootable Windows 7 Installation USB-stick Media. It might apply to making other USB connected "Disks" like Smartcards bootable too.
    I recently had to do this (a Laptop with no build-in DVD drive and no USB DVD drive around). And it turned out to be surprisingly simple, using nothing but build in Windows tools from the Disk. I only found
    this german langauge guide and nothing in english (but I might just have searched after the wrong terms, google has been wierd regarding langauge lately), so I thought I write it up (along with some problems I ran into).
    Making a USB-Stick into a bootable Windows 7 (and propably Vista) Media is a 3 step process:
    1. Create a Active, Primary, FAT32 Partition of 4+ GB on the stick
    2. use bootsect.exe from Windows Disk to create the MBR and Partition Boot Record for that Partition
    3. Copy all files from the Disk to said Partition
    4. Test if it boots
    Detail analysis:
    Step 1 is so simple I doubt it needs explanations. Create enough free space on the USB disk (at worst delete all previous Partitions). Make a Priamry Partition of 4+ GiB. Mark it as Active. Format it in FAT32. The Guide used Diskpart,
    but this step can be done with any Partition Tool under any Windows, Linux, UNIX or DOS.
    While the choice of FAT32 seems a bit outdated, theye propably did not gave the relevant bootlaoder the ability to read NTFS. Or maybe they just though FAT32 is enough for a media that is mostly read. I have not tried what happens if I format it in NTFS, but
    it might be possible.
    Step 2 was the only tricky part. You need the programm "boot\bootsect.exe" from the Installation Media. It also must be run on a non-UEFI booted OS (otherwise it cancels out).
    I had a Windows 8 on a new Laptop so I had a UEFI booted system. Luckily I also had a VMWare Windows 7 lying around. I just assigned the Windows 7 ISO image to the Windows 7 VM, then connected the USB drive to the host.
    Once you have the USB stick in a a proper Windows mount the Parttion you created under 1 under any driveletter (should happen automatically under Windows), and open a console as Administrator (asumes DVD is drivletter is D: and the USB stick's partition
    ins Driveletter E:):
    //Go into the boot directory on the Install DVD
    D:
    cd boot
    //You should see a command promt like "D:\BOOT>"
    //Run bootsect.exe
    bootsect.exe /nt60 d:
    Step 3 is to either copy the contents of the DVD media (copy and paste) or the Image (Mount into Virtual DVD Drive and copy/paste, unpack ISO images contents) into the partition.
    How does this compare to other Distribution ways?
    To DVD:
    There is no need for a DVD drive. Even if a bootable USB-DVD drive is avalible, the Stick or Card will only need only USB port (most USB drives need 2 Ports due the 1 Ampere energy need of the drives).
    Flash Media has no seek times and much better throughput (the old weakpoint of any Disk and DVD/CD in particular)
    A FAT32 partition is inherently writeable. So modifications to the "Installation media" like Implementing Service Packs and other Windwos Updates, Modifying ei.cfg/preactivation/setup answer files, implementing special Disk/RAID drivers into the Windows
    PE or adding stuff that should be installed with Windows is easy (and do not requrie reburning a 4 GiB Image file).
    Since it only needs a 4 GiB partition, on a big USB stick there would still be place for other Data Partitions
    Since it relies on old techniques (Generic Bootloader + Active Primary Partition + partition boot loader), multiple Installation media on a big enough stick might be feasible (with a more advanced bootloader like GRUB). Have to test that part.
    However, the cost/media is a lot higher then a DVD. So if you need multiple Medias it will propably be cheaper to use the old DVD approach.
    Due to the needs of bootsec.exe, first creating the media can be more difficulty then just burning an image. But once it is bootable this programm is no longer needed.
    To PXE/network Distrubution:
    If you have the nessesary setup already (DHCP/PXE Server, powerfull network), the USB stick is likely inferior. The USB stick should beat a 100 MBIT Network easily, but will propably be beaten by a 1 GBIT Network. Network isntallation uses existing infrastructure
    (that you need for other reasons anyway) so the cost per media is even lower then the DVD.
    The PXE way also has even better modifyability - sending out different answer files or even automatically booting different images based on the Compuers MAC adress are tried techniques.
    If you lack the nessesary setup, the USB stick is a lot easier to implement and a lot easier to transport.
    Advanced things:
    Need to check if the partition could be formated as NTFS. I prefer a Journalling Filesystem for my USB-sticks.
    Need to check if using a advanced boot manager techniques (like Grub or modifciations to the BCD of the Windows PE) allows me to put multiple install media on one Stick (with one primary partition per "media"). Especially combining the x32/x86 and
    x64 Windows Installation Media would be worthwhile. As would be inlcuding a Window 8 or Vista installation media.
    Current Step 3 and 2 can propably be switched. I see no reason bootsect could not run from the USB stick as it runs from the DVD (it only accesses the MBR and
    VBR of the Disk, areas not in use by Windows)
    Steps 1 through 3 might be possible from the Windows PE environment. If so, only a computer with legacy BIOS boot would be nessesary (no actuall installation).
    Windows 7 can be installed on a (U)EFI system, but I have not checked if I can use the boot from teh stick on such a Computer. Latest for Windows 8 Media UEFI compatibilty is nessesary.

    I converted the stick to NTFS using the convert.exe and it continued booting. So chances are high they only choose FAT32 in the example because no feature of NTFS was per nessesary in a "almost only reading" scenario like installation media.
    The second part depends on the BIOS. I have a more advanced one where I can choose legacy boot options (like USB stick) in the boot option menu even when the default setting is UEFI, as long as I don't need Secure boot (wich I do not).
    Another question arose: Windows 7 has the Kernel/BCD level ability to boot from .VHD Files. The only thing preventing version below corporate from using this feature is a license check that is run just before the login (so way after the booting has been
    completed).
    Starting with 3.0 Windows PE is based on the kernel of Windows 7. So the instlaltion system might have the ability to boot from .VHD too and might have no such check in place. If so, I could put both versions of the Windows 7 installer into .VHD, reducing the
    need to have physical primary partitions for those.
    Windows bootprocess vs. Linux boot process under BIOS:
    The BIOS goes over all the boot media. If it finds one with a MBR, that one is executed and the BIOS part of the boot process is officially over.
     -> Under Windows the MBR contains the "generic boot loader". A simple piece of code as old as BIOS (25 Years) that looks for the primary partition with "Active" Flag on "it's" disk. If it finds one, the Partition Boot Record of that parition is executed.
    The MBR has done it's part
        -> NTLDR (NT too 2000), this one reads the boot.ini file and gives/executeds apropirate options
        -> BOOTMGR (Vista, 7), this one reads the BCD files
          -> Since Windows 7 BOOTMGR can also chainload the Partition Boot Record that is inside a .VHD File
        -> Wicher was used in Windows 3.X/95/98/ME
    Higher versions can chainload lower versions, but must be designed for this and (re)installed in the proper "order".
    The sometimes odd behavior that Windows 7 tries to keep 100 MiB in a seperate primary partition is there to have proper places for later additions to the BOOTMGR settings. Specifically it allows multiple BOOTMGR OS to use/edit the same BOOTMGR instace without
    running into problems with "whose partition is active?" (since it is always the System Reserved one). It's not disimilar to having an extra /boot partition in Linux or how a GRUB's stage 2 works.
    -> Under a typical Grub Legacy the MBR contains the Stage 1. It directly reads the Stage 2 from the proper partition/file system with a hardcoded path, but due to size limit of the MBR cannot do more. In some cases it starts a stage 1.5 wich has more
    space to do work (63 sectors between MBR and first partition), but I never used this Setup
        -> Stage 2 loads the Grub Configuration from the disk. From here it depends on what OS you want to boot.
            -> For Linux or Unix the kernel is started directly.
            -> Any Windows OS up to 7 can be booted using the chainloader command. For the OS this is identical to having the partition choosen by the Generic Bootloader.
    While it can be chainloaded by the Generic Bootloader from the active primary partition, GRUB and thus Linux has no
    requirement for any Primary Partitions. Stage 1 is designed to directly access the specific File System containng the Stage 2. In fact it does not even need to reside on the same disk (as the Generic Bootloader has to).
    If one does not need the Active Flag to control the Generic Bootloader (because a proper Stage 1 is installed in MBR) it is adviseable to mark wichever Windows Partition is chainloaded as active (up to Vista at least I had very odd behavior if the Windows boot
    partition was not marked active, down to randomly shredded Partition boot managers).
    After running a Windows Setup usually the Stage 1 has to be restored, as Windwos Setup will always write it's Generic Bootloader in the MBR. In order to get "rid" of a Grub all one has to do is overwrite the MBR with the Generic Bootloader and set the active
    flag properly.
