Intermittent Fault With Kingston 100 G2 USB Memory Stick
Hello all,
I have a Kingston 100 G2 USB memory stick (8GB - formatted with FAT32).
I use this stick a lot, and is it a work USB. Just recently my home PC has not been wanting to play ball with it.
This is what happens:
- I plug my stick into ANY USB port on the PC
- No automatic detection, no automatic drive letter assignment, not in Disk Management
- After 2 minutes OR a forced refresh in Disk Management, the device will detect
THEN, either
- The device shows up (is detected), drive letter assigned, and can be accessed as normal.
- Windows reports that the device needs to be re-formatted, and appears as a RAW file system in Disk Managment
Before you ask me to just re-format the disk (I do have backups!), read this:
- The memory stick works on any other PC/laptop fine (including my Win 7 x64 at work, XP Pro x86 on a laptop and in Fedora Linux - and every other PC/laptop it has been plugged into)
- My other memory stick (a Kingston DT1, 1GB) detects as normal - everytime.
So this means the following:
- The memory stick is fine. Its not defective.
- The USB Bus controllers on my HOME PC (the one with the problem) are working
- Disk Management service(s) are working as normal (correctly assigning drive letters)
The only odd thing I can see is in Device Manager, in which this keeps showing up:
WPD FileSystem Volume Driver (w/ Error 31)
I have never seen this before. It doesn't normally show up. I can only guess this is causing the problems?
What I have tried:
- Various ports on the PC
- Safely ejecting, and then reconnecting
- Uninstalling the device driver - Kingston 100 G2 USB driver.
- Uninstalling the device driver for the odd, problematic WPD FileSystem Volume Driver
- Disabling the device driver for the odd, problematic WPD FileSystem Volume Driver
My Configuration:
Windows 7 Ultimate x64 w/SP1
Intel i5 2500 @ 3.30Ghz
8GB RAM

I was just wondering if anyone knew of this problem.
I'm going to continue trying to solve this myself, but any recommendations of things I can try are most welcome.
Thanks in advance,
Dan :)
