I decided to mirror a couple of drives as backups. I make hard copies every 2 months or so. I mirrored a 1 TB disk with disk management in Windows 7 Pro without a hitch. It was so easy I decided to do a 2 TB drive which has turned out to be anything but easy. The original disk with the data refused to change over to dynamic because something had written info right at the end of the disk that couldn't be moved. I tried defragging but it didn't work. I then copied all the data over to the new 2 TB drive and changed both to dynamic after deleting the original partition and reformatting. Still no go. Then I noticed that the new drive I purchased was 6GB/s while the original was 3 GB/s. Is this the deal breaker? Stupid, I know, but I thought I had purchased a 3 GB/s drive trying to match the drives as closely as possible. All 4 drives are plugged into the motherboard. I installed a PCI card, VANTEC 6-Port SATA II 150 PCI Host Card with RAID capability (it works very well too), about 2-3 days ago to get more SATA ports but it didn't seem to affect the 1 TB mirror job so I don't think it had any affect here. I have 2 partitions on both the 1 and 2 TB drives. Most all of the programs are installed to the 128GB SSD boot drive and the 1 TB drive. What can I do to get the 2GB mirrored? Do I have to buy another 6GB/s drive or find a 3GB/s one? Or should I just try the RAID on the Vantec card?
