I bought an 8 Gb SD card a couple of days ago. This is in China knocking her down from 280 to 150 yuan. Got home and my camera, a Canon 640 came up with 'memory card failure.' I then tried it in my computor using a Typhoon 8 in 1 card reader. This time it came up with 'I/O failure.' Nothing wrong with the camera or reader as a 1Gb SD card works fine.
Somewhat peeved I took it back to the shop and they tried it in one of theirs. Up it came, no problems. However, they changed it for another one and I tried it at home again. Same result in the camera, same in the computer.
Some time ago I tried to upgrade my RAM on my laptop to its stated 2 Gbs using two 1 Gb memory cards. It refused to boot with both in though it was fine with either of them plus one of the old 250 Mg cards. This made me believe that the laptop's motherboard couldn't handle the memory.
Just for the hell of it I bought a simple SD/USB adaptor for 15 yuan and tried that. BINGO, up it came and it works fine. Still won't work in the camera though.
Would anybody know why it wont work in my cardreader but does in a dirt cheap adapter.
