I have a USB3 docking station (model USB3-SATA-U3) and an eSATA dock from Vantec. I purchased the USB3 dock because my old computer’s eSATA ports weren’t 3TB+ compatible.
I recently upgraded my computer so that the eSATA ports are now 3TB+ compatible. But then I noticed something weird. When I take a 4TB drive from my eSATA dock and put it into the USB3 dock, I can’t use the drive. It comes up as a “GPT protected partition”. But when I format the drive in the dock and then put it on in the eSATA dock, I can’t use it either. Instead of one single large partition, there are several small partitions . I’m guessing it’s part of the overlay scheme employed by the USB3 dock to make it compatible with older computers.
So is there anyway to make the USB3 dock compatible with my eSATA ports or am I going have to segregate the drives (i.e. one pile for USB3 and another pile for eSATA)?
