Hereâs a screen shot of the error the second MinTTY gives on trying to exit:

The âman bashâ is the command I tried to give, and the âviâ command never executed, even after closing the first MinTTY window. The defunct âlessâ process is of course a child of the âmanâ process.

To be clear, I mean bs=64k count=64M, for 4 TiB of transfer. This ran for about half an hour before it started causing problems in the other MinTTY window here. I didnât write down the amount transferred at that time, unfortunately, though dd did report it. Almost certainly many times more than available RAM at any rate.
