I have a dell inspiron 6400 with a multi card reader, my sony ericsson w810i uses a memory stick pro duo. in order to put it into the multi card reader, i have the memory stick duo adapter, the reader detects any other card , ie. the SD card from my digi-cam etc. it no longer detects my phone’s memory card.. .. what tha hell?!.. any suggestions on how to check where the problem is.
