I was using PD10 with Win7 on mountain lion for a while. I normally stored my Microsoft Outlook data into the Apple SD Card reader because the file size are too big. Having the SD card into the reader will be easier for me to carry around my Macbook Pro. Before I upgraded to Yosemite, everything was fine. After I upgrade to Yosemite and also the latest PD10 patches, I started to encounter the sleep wake problem on the SD card. It happnes almost every time when my close the top cover of hte Macbook pro for few hours. After opened the top cover, my SD card drive got disconnected. Due to Microsoft Outlook will need to direct to the oringinal disk and folder, my outlook cloud not work after it. It is kind of troublesome because I need to restart the win7 from PD10, unplug the SD card everytime after my Macbook slept for few hours. I am not sure if it is the Yosemite sleep wake problem or it is some kind of special use case. Terence
