I have recently purchased and received a Transcend SDHC 8GB (Class 6) card and have successfully installed it onto my phone. I formatted the card. I was able to connect to my Ubuntu Netbook once and transfer files but now it is not being detected by either my Netbook or my PC. I formatted the card again but it is still not being detected. What is the problem? Is it the card, the phone or is it something I don't know about? It just seems odd that it works once and never again. **I tried my 2GB card that came with the phone and now it doesn't work either, anymore.
