Hi, hoping someone can help me out with this. I've just got a 1GB SanDisk memory card to back up some data on and a regular card reader which I have used before with other memory cards and it works perfectly. But today I've tried to access the memory card using the card reader and it takes a while for the computer to do something (I get an hourglass and have to wait for ages) but then end up getting the message cannot access the drive due to an I/O device error. Anyway, I've googled it and tried to find out how to fix the problem but all I get are random forums and discussions with people having the same problem. Does anyone know of any way to fix the problem?
