typically when a SD card goes into write protected state it's because the card is about to fail completely. This is a safety measure so you can recover data before it completely dies.
One last try you can use is the SD Card formatter from the SD association. Works with any manufacturer's card
https://www.sdcard.org/downloads/formatter_3/

If this can't format, then the card needs replacing.

Oh, there is one other cause - if you've put this in a full sized SD card adapter, and that adapter has the "lock" switch put down, it will also cause this.

Oh dear....

OK do this... format the card as FAT32.
Then format again as NTFS.
Solved.

Oh dear is right... :heink: 

Sorry, mate. But formatting any removable storage to NTFS is a no no.
Plus he stated that if he tried a FAT32 format, the system said unable to format. This isn't going to change if NTFS is selected.

The best format tool was linked in my 1st post - SD Association format utility. If that format, then nothing will be able to format.

Had a similar a similar problem reformatting a 64 G Micro SD card. Windows would claim it was write protected no matter which way the switch was placed, on ANY mini/sd converter. Tried the SD card formatting tool as well with no success. Finally tried a microSD/USB converter and it worked like a charm. Nice thing about the SD card formatting tool: It allowed me to see the progress of the reformatting... With the Windows tool, you can't see if it's working, you just have to wait till it tells you it's done.
