Question about SanDisk 1GB Cruzer Titanium USB Flash Drive (413072) Hard Drive

1 Answer

Not recognized by USB

Since we've purchased titanium usb cruzer 1 gb, we have'n been using it for year. as far as i know, it wasn't used at all. so now when i try to plug it in, the blue light flashes for a second, and that's all. no error message, no nothing. as if nothing plugged.
i read here about similar problem, that it can be malfuction, and it cannot be fixed. it's ok with me. but can it be if the device is new? any solution for me?))

Re: not recognized by USB

Go to my documents and select the removable disk drive usually f:, if that does not work switch between a drive and c drive. Usually it takes a second for the computer to realize that the USB drive is being used and for it to be read. Let me know how it goes and if you need other troubleshooting tools.

My U3 Smart SanDisk Cruzer Micro 2.0GB USB Drive Not Recognized

We can fix it -- and recover the data (provided it is recoverable -- which it generally is). If we don't get your data back, we ship the drive back to you and you pay nothing. We've been recovering data for over 16 years and are successful about 85% of the time.

Cruzer micro 1.0 GB


The Cruzer Micro flash drive either uses a proprietary operating system to function and load its set of utilities that include encryption, etc. or it doesn't... most of them do. Without this intact you drive won't function and be recognized. The Operating System is called U3.

Select this link to download the San Disk format, read/write check utility for your flash drive. It will also report back the need or not for the U3 Launch Pad (to be recognized and run in Windows).

Once you have run the utility and it has offered to format your drive from scratch again, if need be, to get it working as it was, and you've been told the drive supports or requires the U3 Launch Pad select this link to reach the download page and choose between the Titanium or Titanium Plus, download install the appropriate U3 Launch Pad operating system.

As you may already know, your flash drive and all San Disk products have a five year warranty. For what these drives cost today the postage alone to send it in would come awful close to the purchase price of another one. But, the choice is yours.

Me, I'm looking at the Cruzer Voyager 8GB to replace my 2GB drive as the Voyager is shock proof and water proof and has been field tested for several months now. Its available at here for half the price as when it first came out. Its selling for $59.99 and there is a $20 mail in rebate that makes the final cost even sweeter.

I hope all of the above information gets you going again and has fixed your problem. Please don't forget to rate this as fixed. I'd get your 1GB drive straightened with my solutions and then get an 8GB Voyager at some point.

USB device not recognized

not fixable.
device can not tell os what it is. that is the most basic of functions.
without id, it can not set configuration needed to access data.
probably already lost data anyway.
replace is about the only option.

sorry for the news
good luck

It sounds like it is trying to use the E: drive and it is already in use? If so while you have the flash drive installed right click on my computer /click on manage / on the left side click on disk management / on the right side you should see the C: drive with other if you see the flash drive in this list with no drive letter right click on it / click on chang drive letter and give it a G: or other letter not in use. you will get a warning click ok and exit out your drive should appear. (note this is for windows xp)

Cruzer Scandisk 2.0 titanium

Hi, Not unless you are using Windows98, your PC should automatically recognize the SanDisk Cruzer Titanium as a "Removable Storage/Device". Driver is not required for Windows ME, W2k or XP. If for some reason the SanDisk Cruzer Titanium (non-U3 devices) is not recognizable, then perhaps it is not a problem with the PC but with the SanDisk. Pls try all other USB ports of your PC (front and back). The SanDisk website provides utilities/software for this kind of eventuality. They are Sansa Firmware Updater and Sansa Connect Recovery Tool. Both are available at Pls be forwarned that some utilities can and will reset your SanDisk to default and any or all data can and may be deleted. Hope this be of some help/idea. Pls post back how things are or should you need additional information. Good luck and kind regards.

SanDisk 1GB Cruzer Titanium USB Flash Drive - device not recognised

I've had this same problem with a number of Cruzer Titaniums. In my case, it seemed to have been due to data corruption. There seems to a section of the flash that is dedicated not to storage but to helping the computer recognize the device. Once this gets trashed, I don't know of a way that the end user can fix the problem. What a waste, because in all other aspects the device is probably still ok. Kind of like a PC with a corrupted BIOS image.
