SanDisk U3 Cruzer 4.0 GB Stopped Working

I have been working with my SanDisk U3 Cruzer 4.0 GB for a month on a MAC and PC running Windows XP at the office. The Flash disk worked OK with the other MAC at home. Yesterday, I tried tranfer data to my Dell Laptop with Windows XP and the light couldn't stop flashing for a long time until the system reported an error. Since then, the flash disk is not working on all of my computers (MAC or No MAC). There is a whole lot of data on the disk that I badly need to save (literally). All I need is to access that data once and then I will through away the disk and not buy another SanDisk ever again. Please help if there is anyone who has managed to sort out this problem. I will watch the site for kind suggesting. EC

    I have been using my Cruzer micro 2GB for a few months now for music in my car radio that is USB compatible. For no reason at all it just stopped working in the middle of playing the other day.

Have you tried using linux live cd's to access the usb device?
You can download a small linux distribution called puppy, burn the iso onto a cd, boot from the cd, at the keyboard prompt go to whatever language and style you are using (US- QWERTY)
then select VESA for display properties, choose the resolution your monitor will support 1024X768X32 etc. on the desktop single click on drives/storage "mount" the usb drive, mount the hard drive, copy files from usb to hard drive.

Try putting in the deep freeze over night and see if it fires up next day.- they do go down these things. I have seen one get so hot the casing started to melt - but it still worked OK

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.

U3 system doesn't run

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:

Hope this helps!

Sandisk flash drive

Is the account that your tying to access the drive with an Administrator account? If not, Log in as Administrator and try to access the new drive. If you ARE using Administrator privileges on the vista machine, the problem lies in the U3 smart driver. Try downloading and installing the drivers for the XP SP2 os on scan disks website, If vista rejects the install package off of the scan disk website, let me know and i'll extract the drivers and build an install for them for you.

I'm guessing you are using a Mac, so you will need a friend's computer with Windows XP or later. Go here for the U3 Launchpad Removal Tool, or Google 'sandisk u3 removal'. The CD image is a hidden partition used by the U3 LaunchPad.

There is aknown issue with the CRUZER crive with U3 not being supported by windows. YOu can reformat the drive in what type, but the U3 is burned on the ROM in the drive........ What this piece of code does is allow Windows XP users to launch applications directly from the USB key, therefore allowing them to "leave no personal data behind". Unfortunately, not only is this a Windows-enhanced technology, it is actually incompatible with Mac OS X. And getting this thing to work on Apple?s OS is an exercise in frustration. The whole idea of a USB key was to replace portable rewritable media like floppy disks, which were universal in their hardware implementation (regardless of OS-specific formatting and file-system). This was true for USB keys as well, at least until U3 arrived. Seek out a different key. Hope this helps.
