How to Repair Corrupt USB Mass Storage or CD/DVD Drivers
For some unknown reason, I've been seeing cases where USB Mass Storage or CD/DVD driver files go missing. This corrupts the respective driver.
- USB Mass Storage Driver - used for external USB storage devices like flash drives, hard disks, and USB CD/DVD drives.
- CD/DVD Driver - used for CD/DVD players. If you have a USB CD/DVD note that Windows installs the USB Mass Storage driver first. Only after the Mass Storage driver is installed and working correctly, Windows installs the CD/DVD driver. If it's an internal CD/DVD drive Windows only installs the CD/DVD driver for it
When driver files are missing, the driver is corrupt and can't be installed. Device Manager will have an entry with a yellow icon - indicating a device error. The device may be listed under "Other Devices" or other places in Device Manager.
Right click the device ->Properties->General tab. If error is because no driver could be found, you'll see device status code= 28
The following instructions apply to Windows Vista and higher.

USB Mass Storage Driver
These 3 files should exist (or the driver is corrupt)
- C:\Windows\inf\usbstor.inf
- C:\Windows\inf\usbstor.pnf
- C:\Windows\system32\drivers\usbstor.sys
If one or more of these files are missing
- Navigate to C:\Windows\System32\DriverStore\FileRepository
- Scroll down. Find the folder name that starts with usbstor.inf_
- You may see more then one folder with name starting usbstor.inf_. IF YOU DO: you want the folder with the most recent date
- Open the folder. There's a copy of the 3 files you need. Copy each one to its correct location as shown above
- Jump to the instructions below to delete the INFCACHE.1 file

Delete the INFCACHE.1 file
- See Add "Take Ownership" to Explorer Right-Click Menu in Win 7, 8 or Vista. (I recommend the easiest way to do this: use the Take Ownership.zip file they provide to update the registry for you)
- Navigate to C:\Windows\System32\DriverStore
- Right click INFCACHE.1 Select "Take Ownership" in the context menu
- Delete INFCACHE.1. Reboot your computer
Windows will rebuild the INFCACHE.1 file and (hopefully <fingers crossed>) be able to find and install the device driver for you!
