I use everyday a SD card to handle the pictures of my Digital Frame, but this morning when I wanted to delete all the pictures I have in that SD card it did appear this message "Error deleting file or folder. Cannot delete pictures. The disk is write-protected. Remove the protection or use another disk".
It is the first time I see something like that, I have no protected the file or folder or disk, nothing.
Here are a few things to try: 1. Unlikely, but this can be caused by malware, are you sure your machine is clean? 2. 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. 3. 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, but don't create them as it's probably a different issue. A. Click the Windows Orb (Start), type regedit, press Enter and navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies, double click on WriteProtect and change Value Data to 0 (zero). B. Now go to HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\StorageDevicePolicies, double click on WriteProtect and change Value Data to 0 (zero). C. Lastly go to HKEY_LOCAL_MACHINE\SYSTEM\ControlSet003\Control\StorageDevicePolicies, double click on WriteProtect and change Value Data to 0 (zero).
