gba ob error. please help

I am using a supercard (sd) for my gameboy. Recently, it started to display "not find the SD. Please turn off GBA" on the screen when I turn it on. I tried reformatting the SD... still the same. When I did a self test on the Supercard. A SD/MMC error came out with error code: 0b (reading flash memory data error). Is there still a way to fix this or is it just time to buy a new supercard ??? I tried inserting a piece of paper with the SD into the supercard as posted in one of the threads. Still won't work!! Help!!

Make sure to blow out dust etc. and make sure it's firmly in.

i did! still won't work... :'(

how old is the SD card, or more relevantly, how much have you used it?. Also try reformatting it.

it's about a year old. don't use it very often. i already tried to reformat.... Guess I'll just have to throw the supercard out the window! :(
:(

try a different SD card, they do wear out eventually.
