G-Raid not showing up in computer management and othe problems with drive.

[kajito1]

I went to connect my 2TB G-Raid on my new computer. Under computer management the external drive doesn't appear. I tried a few things like swapping different esata cable and connecting to a different port but that didn't work. I bought a new esata card and installed it on a PCI slot but the drive still doesn't t appear. I switched over to a USB connection and now in computer management I can see the device as dynamic and invalid. I have the option by right clicking on the drive to convert back to basic but that will probably erase all the data. I switched over to Partition Assistant by Aomei to view the same drive it can see it but still can't repair it. It displays the same "dynamic" or "simple" info. I have the option of doing the same thing convert to basic but it doesn't say that I will lost all my data although I probably will. The data on the drive is extremely important so any suggestion on how to proceed would be appreciated.
