No enclosures involved at all.  In one case the 2.5" drive was in the  
laptop when the partition move issue occurred.  It has been just  
sitting in the open when the read errors started - initially connected  
by SATA to the desktop with the side open, and now by USB connected to  
the laptop.  (I'll move back to the desktop once I get a new disk with  
enough room to do the recovery there.)  The other drive (3.5") was in a  
desktop when it failed, and other than a brief attempt at using the USB  
connection (no enclosure) has just been sitting inside one or the other  
desktop.  Same issue needing more space to attempt any further recovery.
