    I've got Windows 7 RC 64-bit installed on a 2.53 GHz MacBook Pro (dual boot using Boot Camp) with an ExpressCard slot. I also got a FileMate SolidGO 3FMS4D48M-WR 48GB ExpressCard SSD; the drive works beautifully under OS X, but is not recognized at all by Windows 7 when it's in the ExpressCard slot. In Device Manager, the yellow caution icon appears in front of the Standard ACHI 1.0 Serial ATA Controller under IDE ATA/ATAPI controllers. The drive does not show under Disk drives or in Disk Manager. The corresponding Device Status message is: "This device cannot find enough free resources that it can use (Code 12). If you want to use this device, you will need to disable one of the other devices on this system."

    The drive is recognized as SATA under Mac OS X and also works fine in Windows when plugged into a USB port instead of the ExpressCard slot (at which point it is not treated as SATA, but USB). I've tried the latest Boot Camp drivers, but that has no effect. Any suggestions?

    Apple's BIOS emulation for Windows doesn't support SATA, only ATA/133. If you have an older MBP with an intel chipset you can find a solution on this thread:

    Unfortunately for Unibody users like myself with the Nvidia MCP79 chipset there hasn't been a solution found yet - it's discussed towards the end of the thread. I'm going to try and help when I have time but until they find a solution or Apple release what would be quite a simple EFI patch to enable it in the BIOS emulation we're stuck with PATA and your SSD won't work :mad:
