Reformat USB flash drive

Hi, I've inherited a USB 1G flash drive currently formatted as MS FAT16. But I'm having directory problems with it and want to reformat the whole pen drive. I need it to transfer files between macs and pcs.
1. Can I use disk utility to reformat this drive?
2. If so, which format should I choose, and is there anything tricky I need to know before attempting this.
Thanks,
Reed

1. Can I use disk utility to reformat this drive?
Certainly, you can even choose exactly the same format that it sounds like it already has.
2. If so, which format should I choose, and is there
anything tricky I need to know before attempting
this.
The FAT16 format has worked fine for me on all Macs and PCs that I've used my flash drives with. Nothing tricky about it.

  • How to reformat usb flash drive after formatting it in mac

    I know this might sound stupid but I used a 16gb kingstonflash drive for a backup for my macbookpro since there are only few to back up and I was thinking I can copy the backup files to an external disk after. With that said, I used the time machine and it said that it would erase everything on the USB. I clicked okand then once the flash drive was "made compatible", it started to backupbut the total file is 34gb so I can't use the flash drive as back up.
    I tried reformatting the flash drive, but the total free space is 198mb and even if I removed the partition or erase ( I see a hitachiand kingstonpartition when I looked at the disk utility) it never goes back to the 16gb. I checked it with windows and the USB space is also 198mb out of 198mb (free space) I don't know where the 15.9gbwent.
    Any help is greatly appreciated.

    Them do it on a Mac with Disk Utility.
    On Windows you might have to first delete all the partitions before you can select Convert to MBR.
    But try it on OS X.
    Open Disk Utility with the drive connected and select the Top name of that drive in the left most area of the window.
    Then in the Partition Layout drop down select 1 Partition. Then the Options... button will become active, select that button.
    Select Master Boot Record and click OK. The format should already be MS-DOS (FAT) but if it isn't select that. You can give it a name or not. Then Click the APPLY button.

    You can't reformat it and not wipe everything on it.
    Have you tried a different USB port?
    Only other option, back it up on a different computer.

  • How to reformat a USB flash drive?

    I have 1.33 GB available on my Buffalo USB 2.0 GB Flash Drive that is formatted as MS-DOS File System (FAT 16).
    Suddenly, every time I try to copy a MS Word document from my iMac to the flash drive I get the following message.
    +"The item cannot be copied because there is not enough free space."+
    I reported this to the Buffalo customer service and they responded with,
    +"When you look at the files in the USB flash drive, do you see a lot of temporary files? Please delete these. If there is no other solution, I would like you to copy your good files onto your computer hard drive, reformat the USB drive, and copy the good files back onto the USB drive. "+
    I did not see any temporary files, so I'm thinking that I have to reformat the flash drive.
    But how do I do this?
    I've backed up the files on the flash drive to my iMac.
    I insert the flash drive and click on Disk Utility.
    I select the flash drive icon and...
    What do I do now?
    The choices at the top are First Aid, Erase, RAID, Restore.
    BTW, I am running on a iMac 2GHZ Intel Core 2 Duo, 2 GB 667 MHz DDR2 SDRAM, OS 10.4.10.
    As is evident, I have no idea about computers.
    Please advise on a step-by-step basis.
    I thank you in advance for your assistance.

    Select Erase. Volume Format: MS DOS System.

  • USB flash drive not recognized by Macbook Leopard 15.1

    Hi
    Until last week my macbook was able to recognize my USB flash drives and my IPOD in Itunes and also as an independant drive.
    Last week it started to give trouble. It simply does not recognizes any USB flash drives I plug in as well as my IPOD music into Itunes.
    This is very strange since it is recognizing the HP all in one. It scans and prints. I purchased this HP all in one last week and installed the software for it. I am not sure how this could have affected that I cannot mount any USB drives.
    Can you please help? Anyone?
    Thanks.

    Hi
    Welcome to Apple discussions
    Can you see the devices if you use Utilities/Disk Utility? Maybe you need to reformat them. Take care, reformatting will lose the data on the device.

  • How to format USB flash drive?

    I recently received a USB flash drive at a traveling covention. It has two partitions and one is unwritable and is filled with travel brochurs etc etc. I was wondering if it was possible to reformat the whole thing back into 1 partition. I already tried disk utility. Thanks!

    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. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. 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.

  • Why won't my USB flash drive work?

    I am working between two Macs in my house: the upstairs one is MAC OSX 10.6.8, and the downstairs one (an eMac) is MAC OSX 10.5.8 -- if that matters.
    I need to transfer files from the downstairs computer to the upstairs one.
    When I insert a USB flash drive into the upstairs Mac, I am able to save files to it and from it. (I have already read about the correct way to format the flash drive for FAT 32 and read/write, and I eject the drive correctly when I'm finished.)
    Then when I go insert the flash drive into the downstairs Mac:
    the flash drive appears on the desktop
    I'm able to open it, to see the files saved to it
    I can save files off of it, BUT
    I cannot save files to it. I get a message that there isn't enough disk space, which is incorrect -- there's plenty of memory
    I have tried opening Disk Utilities on both MACs, erasing the flash drive's contents, and reformatting it, but I get the same situation.
    I'm guessing the solution is simple and involves the eMac's preferences. Am I on the right track?
    Frustrating.
    Many thanks for your help!

    Niel:
    Thanks for the reply!
    The file on the eMac that I'm trying to transfer onto the flash drive is far less than 4GB.
    So I went onto the eMac's Disk Utilities and reformatted the flash drive as Mac Extended: still no dice. Even with the contents of the flash drive erased, any attempt to copy files onto it resulted in the same "not enough disk space" message.
    So I tried reformatting the same flash drive on the upstairs Mac. Same thing. I tried reformatting the flash drive both as "Mac Extended" and "Mac Extended (journaled)."
    Thoughts?

  • USB FLASH DRIVE WORKS ON MAC BUT NOT ON WINDOWS... CAUSE I ERASED IT IN MAC

    I decided to take my work flash drive home to work on a file. At home I saw that some weird files were on the flash drive and wouldn't delete, so I decided to save my files on my Mac and erase the USB flash drive. I selected the flash drive (by the way it's a 2 GB flashdrive) and I used the SECURITY OPTION 35 PASS ERRASE. Format: MS-DOS (FAT).
    Everything was fine until I took my flash drive to work and plugged it on a Windows XP Computer and it appeared as Drive E I think and when I tried to open it it asked me to format it. I risked it and clicked OK and it said that I didn't have sufficient rights or something.
    SUMMERY:
    2 GB USB ERASED USING MAC DISSK UTILITY
    EVERYTHING FINE UNTIL I PLUG IN THE FLASH DRIVE IN A WINDOWS
    WINDOWS ASKS ME TO REFORMAT FILE
    I PLUG IT INTO A MAC COMPUTER AT WORK AND IT DOES WORK
    IF ANYBODY KNOWS HOW DO I FIX THIS THANKS?

    The drive is probably now formatted for a Mac only file system. To format for a PC:
    Insert the drive in the Mac and start Disk Utility (Utilities folder).
    Select the drive in the left column. Be sure to select the drive (all the way to the left) not a volume (indented below the drive name).
    Select the "Partition" tab.
    Set "Volume Scheme" to "1 Partition" (not "Current" even if it's already one partition).
    Click the "Options" button".
    Select "Master Boot Record".
    Click the "OK" button.
    Enter a volume name (all uppercase).
    Set "Format" to "MS-DOS (FAT)".
    Click the "Apply" button.

  • USB Flash Drive Invisible

    I recently bought 2 new,identical, 8GB USB flash drives, which came formatted FAT-32. I have had different problems with both. Drive #1 was put into a Windoze laptop and had a couple GBs of jpeg and avi files transferred to it. I took the drive home and put it in my MacBook (4GB RAM, Leopard 10.5.8) and it would not mount. I put it in my G4 MacMini; likewise, it wouldn't mount. I returned it to the Windoze laptop, and it ALSO wouldn't mount, except as one pulled the flash drive from the Windoze laptop, for a second a window with the flash drive's contents would flash on the desktop of the laptop. Originally, the flash drive was properly ejected from the Windoze laptop.
    On the MacBook, both Disk Utility and DiskWarrior do not see the flash drive when it is in the USB port (either port). However, Apple System Profiler does recognize when it is plugged into the port. ASP returns the following information when the flash drive is in the high speed USB port:
    Flash Disk:
    Product ID: 0x3234
    Vendor ID: 0x1221
    Version: 0.00
    Serial Number: 10000000000003CF
    Speed: Up to 480 Mb/sec
    Manufacturer: USB2.0
    Location ID: 0x24100000
    Current Available (mA): 500
    Current Required (mA): 100
    (I've also had problems with the other new and identical flash drive, Drive #2, but of a different sort which may be due to a goofy Windoze machine at a public library. It mounts on the MacBook but all the files supposedly saved to it do not appear. I've reformatted it using the MacBook and will start anew with it; however, I have NOT had the visibility/mounting problem with it that I've had with Drive #1.)
    Anybody have any idea what is the cause of my problems with flash Drive #1 and how I can get the drive to mount? Thanks.

    To be honest the first USB drive sounds faulty to me.

  • USB Flash Drive not mounting

    I recently bought an 8GB USB flash drive, which came formatted FAT-32. The drive was put into a friend's Windoze laptop and had a couple GBs of jpeg and avi files transferred to it. I took the drive home and put it in my white MacBook (4GB RAM, Leopard 10.5.8) and it would not mount. I put it in my G4 MacMini; likewise, it wouldn't mount. I am assuming it also won't mount in all my older Macs with USB, either. I returned it to the Windoze laptop, and it ALSO wouldn't mount this time, except as one pulled the flash drive from the Windoze laptop, for a second a window with the flash drive's contents would flash on the desktop of the laptop. Originally, the flash drive was "properly" ejected from the Windoze laptop.
    On the MacBook, both Disk Utility and DiskWarrior do not see the flash drive when it is in the USB port (either port). However, Apple System Profiler does recognize when it is plugged into the port. ASP returns the following information when the flash drive is in the high speed USB port:

    Anybody have any idea what is the cause of my problems with the flash Drive and how I can get the drive to mount? I don't think the problem is a function of my Apple hardware, as my USB ports on all my machines function with everything else USB which I have without problems. Thanks.

    I know that, but I have USB in my older Macs, too, and besides, some of the most knowledgeable people are in these older forums!!
    I've come to the conclusion that the drive may be defective, too, but I was just looking for some possible angle which I'd not already considered. I tried reformatting, but without the drive even being recognized, it isn't even possible to reformat. I can only get ASP to indicate that it is attached.
    Thanks for your try!

  • How to boot from USB flash drive - Portege R500

    Hi,
    I have a Portege R500 running Windows XP, brought about 2 years ago, and recently contracted a worm virus that has infected some of the start up files as the minute I log in it logs out again, even in safe mode! Quickest way I can think of sorting it is to reformat it with the XP recovery disc and reinstall windows.
    Problem!! The CD/DVD drive on the laptop stopped working a while ago, have tried pretty much everything in the thread on this site but had no luck.
    So my plan was to boot from a USB flash drive and do it that way. However in the boot settings I only have the options of HDD / FDD / CD-ROM / LAN, neither of these will work. Does anyone know how to boot from USB flash drives?
    Any help would be really appreciated

    Hi
    As far as I know it should be possible to boot from USB FDD
    Im not sure if you would be able to boot from USB flash drive but its definitely worth a try
    Generally you could try to press F12 button when notebook powers up.
    Then a boot menu should appear on the display and you should see all bootable devices.
    PS: As far as I know the USB booting was available in ToshibaHWSetup (Toshiba tool which changes the BIOS settings in windows OS.) Therefore I assume booting from USB should be possible.

  • How to install (using usb flash drive) os x snow leopard on 10.5?

    i have a version 10.5 (leopard), but i would like to install snow leopard (10.6). i tried using bootable usb flash drive using the "utility drive". However, it did not quite work as i expected. Does anyone know how to use bootable usb flash drive to install snow leopard on leopard?

    How to Install OS X Updates Successfully
    A. Repair the Hard Drive and Permissions:
    Boot from your current Leopard installer DVD. After the installer loads select your language and click on the Continue button. Then select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally. 
    If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    B. Make a Bootable Backup Using Restore Option of Disk Utility:
    Open Disk Utility from the Utilities folder.
    Select the destination volume from the left side list.
    Click on the Restore tab in the DU main window.
    Check the box labeled Erase destination.
    Select the destination volume from the left side list and drag it to the Destination entry field.
    Select the source volume from the left side list and drag it to the Source entry field.
    Double-check you got it right, then click on the Restore button.
    Destination means the external backup drive. Source means the internal startup drive.
    C. Important: Please read before installing:
    If you have a FireWire hard drive connected, disconnect it before installing the update unless you will boot from this drive and install the update on it. Reconnect it and turn it back on after installation is complete and you've restarted.
    You may experience unexpected results if you have installed third-party system software modifications, or if you have modified the operating system through other means. (This does not apply to normal application software installation.)
    The installation process should not be interrupted. If a power outage or other interruption occurs during installation, use the standalone installer (see below) from Apple Downloads to update.  While the installation is in progress do not use the computer.
    D. To upgrade:
    Insert the USB flash drive.
    Restart the computer.
    Immediately after the chime press and hold down the "OPTION" key.
    Release the key when the boot manager screen appears.
    Select the icon of the USB flash drive and click on the arrow button below the icon.
    When the installer finishes loading follow the onscreen instructions.

  • I cannot create a folder on USB flash driver that was format in Windows

    I have a USB flash drive that was format and use for my Windows PC.
    When I used the USB flash drive on my Macbook, I can read the file but cannot create folder.
    Is that the IOS restriction?
    Thanks for replying.

    Click on the drive, choose Get Info from the File menu, and check the format.
    If it's formatted as NTFS, reformat it as MS-DOS, exFAT, or Mac OS Extended (Journaled) as desired.
    If it's formatted as FAT32 or exFAT, use the Disk Utility's Repair Disk command on it.

  • Error code -36 with FAT 32 USB Flash Drive

    When copying files from my hard drive to a FAT32 formatted USB flash drive I keep getting error code -36 errors. I reformatted the flash drive to Mac OS Extended and the files copied fine. I formatted it back to FAT32 and the error returned. I need to use this drive with PC computers at school and can't leave it in the Mac format. Anyone know of a solution to this problem. It didn't do it with my G4 powermac and OS 10.4 but does with the mac mini with 10.6.

    This is a problem I've been dealing with since getting a new Macbook for christmas. In my case I use a Macbook with 10.6.2 at home, networked to a winxp computer, also use FAT formatted USB sticks for backups and taking files to work....and at work I use a mix of winxp machines and older macs running 10.3 and 10.4. I move files around between them all the time, and have had this annoying error -36 file copying problem with the 10.6.2 macbook since day 1.
    I did read about the dot_clean solution, and it does seem to work....sometimes. But the problem ISN'T just when copying a folder full of files. I also have the situation where I work on files in InDesign, and then export a PDF directly to the desktop. I then try to copy that ONE pdf file from the desktop to a FAT USB stick OR to an internet-accessed Appleshare volume, and I will get the dreaded error -36. MOST of the time when I get the error on a single file like this, it did actually copy and is useable on the USB stick / Appleshare volume and I can ignore the error. But sometimes not. Either way, it does show that the problem isn't just with folders of files, or even with the situation of copying a file from mac to windows to mac and then getting the error the next time you try to copy it to a win formatted volume.....you CAN get the error with an individual, just-created file in 10.6.2.
    I sure wish Apple would fix this already!

  • DIsk Utility Hangs When Formatting USB flash drive

    I have a 4gb USB drive (Jetflash by Transcend) that's been usable formatted as FAT. I'd read that i/o would be a lot faster if I formatted as Mac OS Extended instead. In fact, I've done this with previous USB drives with success. When I try to reformat the drive in Disk Utility, it stalls at "Preparing to Erase." I've also tried going through Partition instead, but again, just stalls at the beginning. This is not a freeze or hang or spinning ball moment, but it will just sit there not doing anything. I can quit out of DU at any time. I've left DU alone, thinking this just may take a while, but it has stayed this way up to 3 hours. Suspiciously, there are no blinking lights on the usb drive during this process. I realize every USB flash drive must have different firmware that reacts differently to Macs and I may just be unable to Mac-format this. I've also taken the drive to other Macs all running 10.4.7 with the same results. Any ideas or workarounds will be appreciated. Thanks.

    Update: I've tried on a 3rd mac, my g5/1.8 at home and plugged the USB flash drive to a powered usb hub. Now Disk Utility doesn't stall, but instead immediately states that it can't access the partition map. As the drive has public/private partition capability and also security features, I'm going to assume that's the reason for it to be only formattable as FAT. So now I'm looking for large capacity flash drives that are mac-formattable or find information that throughput is the same on a USB drive no matter how it's formatted.
