This method worked for me: Connect and format new drive Add drive to drivepool to create poolpart folder stop both services (snapraid and drive pool) robocopy data from old drive pool to new drive pool folder robocopy F:\PoolPart.xxxx K:\PoolPart.yyyy /e /copyall copy snapraid.content file if applicable edit snapraid conf comment out (#) old data disk line (e.g. "data dx F:\PoolPart.xxxx" becomes "#data dx F:\PoolPart.xxxx" add new data disk line using old "dx" with new drive letter and poolpart folder (e.g. "data dx K:\PoolPart.yyyy") update content line if applicable run snapraid service run a diff and fix potential changes until "diff" reports only "equal", "restored" or "copied" files. snapraid diff run a "check" audit command limited to the replaced disk to check the check-sum of all the files (replace "DISK_NAME" with "dx") snapraid check -a -d DISK_NAME once everything seems ok, run a sync which should be immediate snapraid sync run drive pool service
