USB flash drive not recognized

G

Guest

I just bought a new 1GB Sandisk cruzer micro usb flash drive embeded with U3
platform. When I plugged the device in the USB port it was not recognized at
all. First I thought it was the U3 platform, so I uninstalled it since I
didn't need it anyway. Since I still had the same problem I updated my main
board chipset driver and my bios, now the computer recognizes it as a "usb
mass storage device", but it won't show up on my computer or the system tray.
When I open the Device Manager, the Flash drive will show up as "mass storage
device," with an exclamation mark. When I click on properties, the window
says "The device could not start." And there are no troubleshooting tips in
the Help and Support section. The Cruzer works fine on all other computers I
use, including all Macs, just not on my home Computer. I'm running Windox XP
Pro SP2.
Thanks for any sugestions.

Hello Soyelkabron,

Thank you for contacting SanDisk Technical Support. It is our goal to
make sure you have all the resources you need to get the most from your
product through your recent inquiry into our product line.

We do apologize for any kind inconvenience this issue is causing you.

We recommend that you plug your Cruzer Micro to another USB port
preferably located near the power hub (usually the rear USB port) or to
an external self powered USB hub.

For troubleshooting error messages on the U3 drive, such as "U3 failed
to launch," do the following:

First set you computer's folder options to show hidden files and
folders and to show protected operating system files. Go to my
computer, documents and settings, user name (your user name) and then
application data. There should be a folder name U3, delete this folder.
Then restart the computer.

For general troubleshooting of u3 drives, do the following:

Let us first begin by verifying that you have FULL administrative
rights on the computer that you are attempting to use, as that "U3"
does require that you do in order to properly utilize the device.

Please note that the device is only supported in Windows XP Service
Pack 2 and Windows 2000 Service Pack 4.

If you do have SP 2, let us be sure to try all of the USB ports on your
machine particularly the back ports as they receive more power.

Next we would want to try disabling all of your items on "Start-Up".
Start-Up items are pieces of software that run automatically whenever
your PC is first turned on. Certain pieces of software are prudent, in
general, to have on start-up (e.g. Anti-Virus software), while other
softwares are more menial in scope (e.g. AOL Instant Messenger). Since
all programs can be manually started, in general, the only softwares we
want in start-up are programs that we know that we are going to use
everytime that we use the computer and would, thus, prefer that they
start automatically.

To disable your start-up items, SINGLE LEFT CLICK on "START", then
SINGLE LEFT CLICK on "RUN" from the menu that appears. When the "RUN"
dialog box appears, please type "MSCONFIG" into the "OPEN" field, then
press the "ENTER/RETURN" key on your keyboard. This will bring up your
"SYSTEM CONFIGURATION UTILITY". From there, click on the "STARTUP" tab.
Once having done so; (Please make a note of the items in your start up
menu so you can reinitialize them later) you will notice two buttons at
the bottom that say "ENABLE ALL", and "DISABLE ALL". Click on "DISABLE
ALL", and then click on the "OK" button at the bottom of the window.

A prompt will appear on your screen saying that you need to restart the
computer for the changes to take effect. Please ensure that your "U3"
is not plugged into your computer, then click on the "RESTART" button,
and allow your PC to totally reboot. Once your PC is back up and
running, let us plug the "U3" back into your PC.

Did we receive the same error? If not, let us simply reload each of our
start-up items, one at a time (restarting your PC in between each,
always unplugging the "U3" first), until the error repeats itself. Once
the error repeats itself, we will have found the conflict.

If the error persist, let us move on by disabling any firewalls and
Anti-Virus software that you may have running on your computer. If you
are concerned with getting a virus or such during this process, you may
simply disconnect your computer from the Internet, as it will not be
necessary for any of our troubleshooting steps.

Once you have disabled all of the securities on your PC, please reboot
and, again, once back up, reinsert the "U3" back into your PC. If it
solved the issue, reinstitute each item one at a time until we uncover
the culprit.

If the matter persists, let us try another PC, preferably one outside
of your present environment (if you are using the device in office, try
it at home, or vice versa) but, again, one on which you can gain full
administrative rights to.

**To stop the U3 from launching, you can disable the auto launch in
windows simply by holding down shift when inserting the device.**

Some CD-ROM or DVD burners are bundled with software that may conflict
with the drive letter on which your smart drive is installed. Although
there has been no formal testing to date of the various packet writing
software applications in the market, it is advised that you uninstall
the software and then try inserting the smart drive again. If the
problem is resolved, please contact us at (e-mail address removed) with the
name of the packet writing software installed on your computer.

Examples of such programs are listed below:
- B's Clip (from BHA)
- Data Add 2.0 (Ulead)
- DirectCD (from Adaptec/Roxio)
- InCD and Nero 7.0
- PacketCD (from CeQuadrat)
- RecordNow MAX, MyCD, PrimoCD, PrimoDVD and DLA (from Veritas)
- Write DVD! (From Software Architects)

If the device works on another PC, then you might want to contact your
PC manufacturer, a PC Technician, or Microsoft for assistance.

For registry and warranty purposes, please provide information on the
following.

Should you have any further assistance, inquiries or concerns, please
do not hesitate to reply to this e-mail.

Best regards,
