Remove the write protection from a USB flash disk

I have a Raidon GR3630-2S-SB2+ External RAID enclosure that I've just hooked into my system. For some reason, it's coming up as write-protected.

The issue seems to have to do with my Windows setup, because I'm able to write to the drives when I plug the enclosure into another system running the same version of Windows (Windows 7 Enterprise x64).

For both of my machines I have administrative access, and "Full Control" is granted to Administrators in the Security tab of the drive properties.

Does anyone know how to enable write access to an external drive like this? Are there any other steps I could take to troubleshoot the problem? Or is there any other info that you would need?

Thanks in advance!

Put this in a .bat file and execute it:

reg add "HKLM\System\CurrentControlSet\Control\StorageDevicePolicies" /t Reg_dword /v WriteProtect /f /d 0
