You can try a registry tweak, if you are brave ! Disable Write Protect.
Use regedit to change dword value.

Enable and Disabling of USB write protect using regedit

1 - Enabling USB write protect

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies]

“WriteProtect”=dword:00000000

2 - Disabling Write Protect

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies]

“WriteProtect”=dword:00000001

This page showed me how to remove the write protection of my external USB hard disk which had write protected itself: http://www.online-tech-tips.com/computer-tips/fix-media-is-write-protected-in-windows-7/

DISKPART> attributes disk clear readonly

Disk attributes cleared successfully.

At least my case there was no "StorageDevicePolicies", hope this helps someone, sure took me long enough to find it...
