No all the drives Still show up...i downloaded the lastested and installed it....but i think i found the problem. I accidently put my C:/ (system) drive in the pool. As my pool filled the C drive up (as it appeared as far as i could tell to be the pools first choice to send things) the more unstable my system became i think. Anyways i had to delete all my data a little at a time to remove the drive or it would hang and crash. Whether i tried to to large deletes or removing disk....it wouldn't hang till i did it chunk by chunk and everything was gone. Thankfully i run dual independant servers for just this kind of reason. I am now transfering my files back and thus far the pool seems to hold and not crash every 5 minutes. I have about 12TB of data to move so it will take a day or two but should be a good stress test as to the pools stablity. i'll keep you in the loop if it crashes further i will hunt down my logs and up load them. thanks for your help. I think you generally have a great product
