8gb SDHC SD cardwrite protection removal

I’ve been reading some older posts on how to remove the write protection, but nothing has been working for me.

I tried putting tape over the switch for the Unlock/Lock, nothing still. 

I tried putting the switch slightly to the locked position, nothing.

It’s not my laptop’s reader because I have a 2gb Toshiba SD card and it’s working fine.

Trying to transfer files from my 2gb SD card to my new 8gb SD card, but having no zero luck.

Edit: It is a legit SD card from SanDisk. Bought it from BestBuy. And has a serial number at the back
