Windows 7: Flash Drive Showing Up As Itself & Generic Volume

Flash Drive Showing Up As Itself & Generic Volume

I'm not sure if this goes here or in the hardware & devices area. I'm not sure if it's a driver issue or something else.

My 8GB SanDisk Cruzer Micro is not working properly(default FAT32) on all four USB 2.0 ports. My other flash drives work fine, also FAT32. I recently upgraded my laptop from Windows 7 Release Candidate to the RTM Pro version by performing a clean install.

In Device Manager, the SanDisk Cruzer Micro device status is: This device is working properly.
The device status of the Generic Volume is: This device cannot start. (Code 10)
Device type: Storage Volumes, Manufacturer:Microsoft, Location: on Volume

My flash drive is no longer being recognized as being formatted or having any data on it in Windows 7 Pro in Disk Management. This is incredibly weird because I've been running 7 since February (the betas & the RC). The drive worked perfectly until I installed the RTM on Tuesday. If I plug it into an Apple laptop, it works & I can see the data. If I plug it into a Windows XP computer, it works & I can see the data.

The drive is showing up in the Device Manager under two places: Disk Drives (which is where it should be) & under Storage Volumes (as a Generic Volume) By uninstalling the Generic Volume in Device Manager & scanning for hardware changes, the drive shows up in My Computer as usable (at least until I use the drive on any operating system other than a Windows 7 computer). Then the Generic Volume shows up again & it stops working on WINDOWS 7 computers once more. This is incredibly frustrating & terribly inconvenient.

Right now, I have to uninstall the Generic Volume every time I use it on a different system. I have tried formatting the drive on XP & 7 as FAT32 & NTFS. Same problem, no matter what I do. I also reinstalled Windows 7 Pro again as a clean install. No luck there either.

The drive works perfectly, it's a Microsoft problem. I contacted Microsoft Tech Support. I tried to chat with them through IE 8. Surprise, surprise. I was unable to type anything in the chat box to communicate with the agent. I decided to use a different browser that I know works. The support agent "helped" me for about four hours. Making me do EVERYTHING I'd already done, multiple times, multiple ways. I was then told I was being referred to the Microsoft Research Team and to expect a call 24 hours later with a 2 hours window. That was at 9pm Friday night. Still haven't gotten a call. Never got the e-mail either that the Support Agent was supposed to send.

The support agent couldn't seem to grasp that the problem was basically that the drive is showing up TWICE in device manger as itself & a generic volume. Here is a screen-shot of my device manager. Click here for the screen-shot.

Have you tried any other thumb drives in your 7 machine?

Try updating your USB and chipset drivers also.

Thank you, I hope this forum will be more helpful than Microsoft has been.

Yes, as I stated in my original post my other flash drives work fine. I did not mention that all of my external hard drives also work properly.

I have the latest Windows 7 drivers.

It's really weird having to uninstall that Generic Volume in order for the 8GB SanDisk Cruzer Micro drive to work.
