Micro-sd In Android Tablet Is Read Only... I Can't Seem To Change It

My neighbour's tablet has a micro-sd card but it seems set on being Read only.
I came across this tutorial
How to remove read-only from SD card using CMD?
Step 1. Plug the read-only micro SD card into Windows.
Step 2. Click Start > Run > cmd.
Step 3. Type diskpart and run diskpart.exe.
Step 4. Type list volume. Now you'll see all your connected drives, see which one is the memory card drive.
Step 5. Type select volume #. # represents the letter of your memory card drive.
Step 6. Type "attributes disk clear readonly" > removing the write protection.
Now open your SD. You should be able to edit, delete, copy or move files without a hitch.

Unfortunately on replacing the micro-sd card into the tablet I was still unable to copy files onto it.
A information box opened to say that the card was still Read only.
Any thoughts or suggestions?

Thank you Eldon I shall give SDFormatter v4 a go. I have it sitting there on my desktop.
Thanks again,
