Usage is my problem as both will appear under the LR1 and LR window as well will EHD2 & EHD. The problem arises when I try to the transfer operation between the 2 EHDs I can choose one EHD in the 1[SUP]st[/SUP] block and immediately the 2[SUP]nd[/SUP] block changes and only permits transfer into the Hopper as opposed to allowing transfer into the second EHD. Am I expecting to do something not permitted or is it impossible technology for 2012? TYIA
