Try changing the drive letter and check three registry keys:
- Plug in your device, right-click My Computer > Manage > Storage > Disk Management then right-click the graphic icon of the device and select Change Drive letter, then change it to one nearer the end of the alphabet.
- If it still isn’t working, check/change these registry keys but create a system restore point first, just in case you have problems. Note that the keys do not necessarily exist, so don't create them as it's probably a different issue.
