Hello, I have a 1GB VGI Memory Max SD card which I place in a Verbatim mini SD/SD card USB reader. When I plug in the reader (tried various USB ports), it is recognized in windows explorer as Removable Disk ( J: ), yet when I open it or view it's files it hangs and windows explorer stops responding indefinitely. I've tried a 4GB SDHC card in the same reader and it works fine, so I think the problem is with this specific SD card. The SD card is not locked. Anyone have any ideas on how I could fix this?
