SDFormatter will not work with Latitude 3330, Windows 7 Pro and O2Micro SD SCSI reader

Hi All

I'm trying to use SDFormatter from www.sdcard.org and can't get it to work in the SDMMC socket on my laptop.  When I click the Format button it gives an error message:

"Could not format memory card"

If I plug in my USB card reader, it works fine.  If I insert the card into an HP Pavilion with Windows 7, it works fine - it just doesn't work with the integrated SDMMC card socket.

Has anyone else had this problem?

Kind Regards

Steve
