*sigh* tape isnt working, guess Its time I get a new reader or something
Before you do that, you can also try this:
The SD Cards' "Write Protection" issue is not a software issue or any computer related problem. It is not the problem with your SD card either. The real problem lies in the Card Reader itself, a stuck WRITE PROTECTION SWITCH in the card slot. Peer inside the slot and you can see on the left a copper lever switch. This is the WRITE PROTECT SWITCH.
If your card reader is out of warranty, you might want to do this simple repair yourself to save bucks:
Loosen the screws and open up your card reader. If you can have access to the card slot metal cover, you can see that there is a certain hole on the left just outside the copper switch we mentioned awhile ago. Confirm the location of the switch and if it is in line with this hole by peering once more inside the card slot.
Now insert a needle or a pin inside the hole and push slightly the lever away from the card slot wall, being careful not to breack the switch. This will cause the copper lever to bend slightly inwards from the card slot.
Test if you're successful with this repair. Without the cover on, connect the card reader to the computer and insert the SD card. If you can now manage to manipulate your files by erasing them, or formating your card, then you're done. Replace everything back inside the cover, and your done!
