Is it mandatory to install special seagate drivers


if you use a 3 TB SATA disk over external eSATA expressCard Adapter?

I have an old and a new 3 TB disk, both make problems, the partitions are visible, but check disk runs every 3rd time, copying to each other doesnt work good, one partition lost a whole folder which is now shown but empty, mainly if I connect the adapter over old usb2. So do I need specific driver or is Windows 7 partitioning to GPT MBR enough?
