SanDisk Cruzer 4GB Micro - not recognized by computer

When plugged in the USB Port, the device lights up (continuous light), but the computer does not recognize it as a removeable storage device or any other device. I've taken the device to several other computers with the same result regardless of the operating system (Windows XP or Vista).

This is a known issue at SanDisk but the fixes listed on the website have failed to produce any results or even be applicable to this issue.
I don't believe the device is faulty because too many users have this very same issue. You'd think SanDisk would be more customer friendly if they want to sell any more devices rather than leave so many customers stranded.

Well, Hello!

The Scandisk use two drives. One is a cd-rom emulation where the U3 utility resides and run. the other is the disk itself. Try the device on other computer and try other usb devices on your computer and analize the results. Note: On a Mac you only will see one disk drive.

Is your computer recognize other storage devices and you U3 disk doesnt work on other computer the drive is most likely to be corrupted. In this case you will need to install the uility from Sandisk to recover the functionality of your drive.

When i plug my 4g cruzer micro usb memory stick nothing happens the cpmuter dosnt read that it is plugged in


Try a different USB device on each of the USB ports on your computer.
Hopefully, all your USB ports are working correctly.

Try a different USB port on your computer.
Hopefully, the SanDisk will be detected on one of the ports.

Try a USB port on a different computer.
If the SanDisk still is not detected, then spend $10 to buy a new 4GB flash-drive.

Cruzer micro 4gb does not start on windows xp


If you are using Windows.
Open the Windows explorer.
Plug the device in a USB port and wait for the computer to recognize it. After it is recognized the Windows Explorer will show two additional icons, one of them a CD-ROM.

Click the icon with the CD-ROM, and it will execute the U3 operating system. A small yellow icon with a U3 label will appear on the task bar. Right-click the icon on task bar and select the "Open U3 Launchpad". Point to the Settings button on the right side.
Right click that button and select the U3 LaunchPad settings

In the window that pop up point to "Autorun" button and click it.

Click the button that will say Enable.
After that it will launch automatically whenever the device is recognized by a computer.

If the U3 launchPad is missing from the device you can download it from the SanDisk site. Here is the link. Download it and install it on your computer. Note:It does not launch on MacProducts or Linux.

I plug in the sundisk cruzer 2.0 GB USB device and all it does is blink. It will not show up on my computer for the drive.


Hello

If the computer recognize that there is a device plugged into the system, then just try to plug the flashdrive into another port at the back of your case.

If the computer does not recognize that there is a device plugged in, there is a problem with your flash drive. It still gets power from the computer(Bliking light), but there is no data transfer between computer and flash drive.

If it is still under warrenty, send the flash in for repairs(presuming that your USB ports work), otherwise try and see if it works on a other computer. If it does, the the problem is with the USB ports on your computer. I really hope this can be of help.

Best regards
Andrea

SanDisk 4GB thumb drive not recognized by my computer


Try any other computer but not open drive only see if they can read it. Also change USB port, sometimes some ports dont accept devices. Also check for latest antivirus software last such case viruses dont let me read any of my USB drives. If driver works to oter PC then you have virus.

San Disk Micro Cruzer 4GB


Hi there,

Try plugging it in to a different USB port on your computer. Make sure the connecter on the Cruzer is clean and there's no dust inside.

Also, try plugging it in on a different computer.

If none of these work,
I'm afraid it's a hardware problem and there's nothing that can be done about that.

Hope I helped!

My computer do not recognized my Sandisk Cruzer Micro 1.0 GB.


I had the same exact problem on my 8G card. It worked fine in the camera, but when I plugged it into the card reader it flashed once and then the light went off. So, I put the card back in the camera and ran a USB cable from my camera (there was a port on the side of my Cannon Powershot that was smaller than a USB, but I don't know what to call it) to my computer. When I turned the camera power on, the computer was able to read the 8G card while it was inside the camera. I downloaded everything to my computer at that point. Hope this helps! I got the chord from my external hard drive and that fit from the camera to the computer.

SanDisk Cruzer 4Gb not found on XP


I have the same issue. I have found a temporary solution though. I have a Sandisk 4GB Cruzer and an HP Laserjet 1022N connected VIA USB. When I uninstall the USB Printing support driver from Device Manager then plug in the Cruzer it recognizes it right away. Not quite sure why this would happen though
