    Sandisk Cruzer "Contour"4 Gb Flash Drive just will not initialise. I get "Error 1010"each time. A propduct which does not work should not be on the market. Others have the same problem. How do I correct it - if this is possible ?

Sandisk offers a program that completely wipes the Cruzer (including the partitioning), turning the drive into a pure unit. This is a permanent solution, and one cannot restore U3 functionality once this has been done. I hate the U3 stuff, so this is something I do with every Cruzer right out of the box.

Doing a search on Google for 'u3 removal' yields a few links, but at this moment, I'm running into a lot of broken links, and the original page on Sandisk's site (where I got the utiliy in the first place) is broken. I use the utility far too much to not be sure of having access to it, so I made sure to have it in my numerous 'essentials collection' CDs at home and work, as well as on my personal page in case I ever was somewhere without the CD.

One note about the version I have.... it is the Windows program, so if you have a Mac, you'll have to go to Sandisk and get the Mac version. I have no idea whether there is an option in Linux, but I'd be surprised if someone hasn't done it. Again, the Google results I got seem to have a lot of potential

Another thing, I have used this program flawlessly on a pile of 1GB and 2GB Cruzers. As far as I know, it will work on other sizes, but just so you're aware, I can't be 100% sure of that.

If you want to grab the Windows executable from my collection, go here: http://www.rawbw.com/~zio/misc/u3/U3Uninstall.zip

Hope this helps!

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

My sandisk cruzer 4 GB pendrive ws working fine but now whenever i try to format\copy\cut it shows location 0 with used space 0 free space 0 what should i do


Your flashdrive usually shows 2 drives when inserted to your computer, one is the U3 drive and the other one is the removable disk drives. U3 drive is your separate partition for the U3 system and in order for you to store, copy, format your flashdrive, you should be selecting the removable disk drive, not the U3 drive. U3 is a read only memory drive that is responsible for your U3 to work (just like portable applications). Hope this helps.

How to download softwares to my sandisk u3 flashdrive


Hello,
As you may know your U3 Smart drive has a small OS that allows you to run Your applications on another computer. This OS shows as a CD-ROM icon on which you click to execute the LaunchPad (TheOS) of the Cruzer. In addition to that you have the icon of a regular drive. (Usually the Drive letters are consecutive G and H for exemple.) When you safely remove one both are unmounted at the same time.

Once the LaunchPad has been executed, it installs an icon on the sys-tray. When clicked, that tray icon opens a pop Up window, giving a menu of the applications installed and which you can run on the host computer, but from your drive (U3 Smart Programs on the left) and on the right various menu options
  1. to explore the drive,
  2. configure the drive(settings),
  3. add programs (to download additional U3 programs),
  4. and enable security. etc.
7f42ffc.jpg

So if you want to download additional U3 Programs to run from you drive you use the Add programs (option 3 in the list above)
However, if you just want to put regular files on the drive (pictures, text documents, etc.) you do as you woul for nay drive: You drag and drop the files, not on the CD-ROM icon, but on the other drive. You can also use the Explore option (option 1 in the list above) to open the second drive to see what is in it, add files, remove files etc.

Hope it helps
