I've seen countless issues with sandisk USB drives and this is what I did to fix it. Please note, this involves moving files around and if your not careful you could make things horribly worse.
A few things to note
2.I then copied the file usbstore.inf from C:\Windows\System32\DriverStore\FileRepository\usb
3.When I scanned for hardware changes in Device Manager, (you should see the name of your computer at the top, just right click and select scan for hardware changes) this time it picked it up as the correct device and installed it as a USB mass storage device.
Although I didn't try it, I suppose it's also possible to simply remove the original usbstore.inf file from the c:\windows\inf directory and put it back later instead of copying the other one.

ok not sure about moving files but i had this same issue, but i couldn't see my usb drive in my linux os either, so here is how i fixed it, and can now use it in win7 or Kubuntu
First I downloaded a free partitioning software called EASEUS it could see the usb stick and i told it to wipe all data and partition to a FAT32 after that windows was able to see it as an empty drive and I was able to make a Kubuntu startup disk, which is what i got it for. By the way the process too a long time to wipe and partition.
Hope that helps anyone else who might have this issue

Just to give this a much deserved bump, after purchasing a 32GB Cruzer and not being able to get it to recognize on a Win7Pro system at all, I found this thread and it solved the problem.
In my case, there wasn't a usbstor.ini at all in the inf directory, but copying it over from the FileRepository did the trick . Fantastic! I had just spent 30 or so minutes with tech support and if I had found this before then, it would have been unnecessary.
Very cool and thank you to the OP for sharing this excellent workaround.

I saved files on this Scandisk Cruzer 8 gb How do I get files off? Disk was to reformat itself?
Data has to be on it what do you think I should do to get files off scandisk?

"Disk was to reformat itself?"
Sounds like the file system has been corrupted. Usually caused by not using Windows Safely Eject function. See if running CHKDSK from a Command Prompt helps correct the FAT.
