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.
Yes I think it was a corrupted MBR . The G-RAID was removed from my old computer to a new computer. Anyway I used two programs to fix the problem Testdisk which is a free utility was able to rebuild the MBR. After that I used AOMEI Partition Assistant Pro to covert from Dynamic to Basic and Presto it worked. Hope this walk-through might help anyone with a similar problem. BTW Partition Assistant is not free however Testdisk will allow you to convert from Dynamic to Basic but it's a DOS based program but not difficult to use.
