For the step where you're moving the data from the hidden PoolPart folder on your E: drive, are you moving the data to the new D: drive pool, or to the F: drive you created from the new 55TB of space? I have a slow upload speed, so I really don't want to wait months to reupload 7TB of data.
And what is the purpose of creating the F: drive? Why create a new drive rather than just expand the size of the E: drive and add it to the D: pool all on its own? Is there an advantage to having 2 partitions rather than just 1?
