SD card problem

[x88a]

Hi. I am having a very frustrating problem with my SD card.
I can copy files from my SD card.
But i can neither delete files from it nor copy files into it.
I cant reformat it also.
It says my card is write protected, but it isnt locked.
How do i solve this problem???
Pls dun tell me to put a tape at the lock. It juz doesnt work.
I m in desprate need of this SD card.
The space in my hp is too little for songs.
Pls help.
TQTQ

Really, it must be the little lock switch on your sd card... Try to put it in the locked state, maybe its inverted? :P

Nope, its not the lock.
I tried it both locked n unlocked.
Doesnt work.
I dun think the prob is with the SD card.
Coz the SD card works in other comps.
