How do I format a Sandisk Cruzer for Macintosh and get rid of the U3 System? Thank you, Fred Wagner

    I did exactly as you recommended, but it only partitions the part of the Cruzer that was available in the first place. The U3 System was still there. I understand that the Cruzer has software on it that can only be read by a PC and with that software you can delete the U3 System and then reformat the Cruzer on a Mac. Then you should be able to use the entire Cruzer without the U3 System coming up all the time. I will try this as soon as I can get near a PC.

You can't fully erase that device until you modify the partition info.
If you will be only using this flash drive on a Mac - open Disk Utility, click on the flash device (not the partition, but the manufacturers info line), and click on the partition tab. Click on the dropdown under Volume Scheme, and choose 1 partition, then click the partition button. Mac OS Extended should be the default, and that will be OK.
If you will be installing some other operating system, such as a Linux distro, then you'll need some support for that, with the correct type of partition.
Mac OS Extended will be good if you will only use on the Mac.
You won't likely get OS X to install on a USB flash drive. You'll need a windows PC to uninstall the u3

My computer was worked on recently and now it will not allow my San Disk Cruzer USB Flash Drives with U3 security to load. The error code says" U3 Launchpad will not launch due to missing one of its c


Repair a U3 Flash Drive U3 Smart Drives are USB flash drives from SanDisk preloaded with smart applications that run directly from the drive. With smart applications such as Firefox and Skype installed, users can run these applications on Windows computer without installing and setting the applications up on the computer itself. According to the SanDisk website, it is possible for the file system on U3 flash drives to become corrupt or for other disk errors to occur. SanDisk provides two possible solutions for repairing a U3 Smart Drive that prompts an error message or is unresponsive when plugged into a computer. b> Repair File System on Drive that Prompts Error Message b> Launch Windows Explorer by clicking on the "My Computer" or "Computer" icon on the desktop. Right-click on the drive letter for the U3 Smart Drive. Select "Properties" from the pop-up menu that appears. Click the "Tools" tab in the Properties window that opens and click "Check Now." Check the check boxes next to "Automatically fix file system errors" and "Scan for and attempt recovery of bad sectors" listed under Check Disk options. Click "Start" to repair the file system on the U3 Smart Drive. Once the Check Disk procedures are complete, check to see of the drive is working properly. b> Repair Unresponsive Drive b> Plug the U3 Smart Drive into a different Windows computer. If the drive works on the computer, proceed to the following steps. If the drive is unresponsive on other computers, it is malfunctioning and should be returned to SanDisk or the place of purchase. Disable password protection on the U3 Smart Drive by clicking "Disable Security" in the U3 Launchpad window and entering your password to confirm. This may allow the drive to be accessed on the original computer. Update the U3 Launchpad software. Click "Status & Settings" in the Launchpad window and choose "U3 Launchpad Settings" and "Check for Software Updates." Allow the system to check for updates and follow the provided steps to update the software if an update is found. Eject the U3 Smart Drive by clicking on the "U3" icon in the system tray and selecting "Eject." Plug the drive into the original computer to see if it's working.


Remove U3 From a Cruzer Micro Drive b> USB flash drives (thumb drives) offer people a portable, high-capacity alternative to carrying floppy disks and emailing files to themselves. Some drives include a software suite with features that include quick navigation and other functions. U3 makes a software suite that offers navigation and software installation functions. For some, this software is useful, and for others, it's a nuisance. Removing the U3 software from your Cruzer requires bit of effort and some technical know-how. Insert the drive into the USB port of your computer. Back up any important data on the drive at this time. Open the U3 software manually if it does not automatically launch. Click the "Settings" option, which is displayed on the right side of the menu, second from the top. A context menu will pop out; select the "U3 Launchpad Settings" option from the context menu. Click on the "Uninstall" tab located on the left side of the "U3 Launchpad Settings" menu. It is the second tab from the bottom. If you do not see the "Uninstall" tab, go back to the first page and click "Help and Support." The "Uninstall" option will be displayed prominently in the "Help and Support" menu. Close any other open windows or running programs. An "Uninstall U3 Launchpad" button will be displayed in the "Uninstall" menu. Click it to uninstall the software from your device. The area on the drive where the U3 software is stored will be rendered blank. Stop the device by clicking or right-clicking on the device's icon in your system tray. A context menu will pop up and display the option "Safely Remove Hardware." Click that box to "stop" your USB device for safe removal. Remove your drive and then reinsert it to check that the U3 software has been uninstalled. If it has, your device is now ready for use. If it has not, repeat Steps again. If the Uninstall utility is not available on your drive, or the previous steps did not delete the software, download the appropriate uninstall software for your computer (.dmg format for MAC and .exe for PC; see Resources for links). http://mp3support.sandisk.com/downloads/cruzer-utility-mac.dmg Follow the steps provided when running the utilities to remove the U3 software.


b>Get Rid of U3 SanDisk Program b> SanDisk is a company that manufactures flash storage devices. Most flash drives do not come with any extra software installed. However, SanDisk drives come with U3 Launchpad software. This software provides a graphical user interface (GUI) that allows you to access different areas of the file system. It resembles the Start menu of the Windows operating system. You may, however, not want the U3 Launchpad installed because it automatically launches every time you plug your drive in. You can remove this software without the use of any third-party application.

http://kb.sandisk.com/app/answers/detail/a_id/2550 Insert your SanDisk flash drive into the USB port of your computer. Allow the computer a moment to recognize the drive. Click the U3 icon in the system tray. The system tray can be found in the lower right-hand corner of the screen. Click on "Settings" located in the right-hand column of the U3 Launchpad. Then select "U3 Launchpad Settings." Click the "Uninstall" link on the left side of the window. This should be second to last button displayed. Click the "Uninstall U3 Launchpad" button that will appear in the middle of the screen. Click "Next" to continue. Click "Yes" when asked whether you want to restore the data after the U3 Launchpad is removed. Clicking yes will allow you to save your data. If you click "No," all of your existing data will be deleted. Click the "Format" button. Hope this helps. If all of this fails Contact scan disk http://www.sandisk.com/about-sandisk/contact-us.aspx

How to format a verbatim Store "n" Go part# 95401? I am looking for the software for reformatting it and can not find it.


  1. If you’ve used the device before, make sure you’ve gotteneverything off of the drive you need. You’ll be reformatting it. (Theapplication may have an option that allows you to keep the data – Idon’t remember – but better safe than sorry.)
  2. Plug in the drive – the U3 launchpad will load. You can close theU3 tour program and whatever main window pops up if you like, but leavethe U3 launchpad icon in the system tray enabled (i.e. don’t exit thelaunchpad application entirely).
  3. Download SanDisk’s U3 Launchpad Removal Tool (opens in new window) – as the site says, make sure the USB device is plugged in and Launchpad is still running.
  4. Run the tool, and choose the option which completely removes U3 and formats the drive.
Voilà, you now have a regular old USB drive which you can break in any way you want.
(NOTE: If the SanDisk tool above doesn’t work for you, you might try the uninstall tool from u3.com – I had no trouble with the SanDisk tool, but I can only speak for myself!)

When I plug in my sandisk u3 titanium 2G cruzer on mac I only get u3system icon - the cruzer icon does not show up


How do I get the sandisk cruzer 2.0 titanium to show up on desktop - only u3 system shows.

Yes, it did work prior on my old emac with Panther macosx v10.3.9 and on a new imac. Sometimes it would eject fine and other times after I ejected it and after the icon disappeared, - It would bring up an error message that it was ejected wrong and might have problems.
That is what it said yesterday and when I tried to use it again - The only icon that shows up is the u3 system.
