The problem is that no file management operations can be performed on
And, the computer is not capable of transferring about 200GB of data,
in less than about six months or so - for stable data transfer, if
still possible on the computer (given that I would not even be able to
mount another external HDD, at present), it is best to limit it to
abouty 1 GB per day, possibly, 1 GB per boot session.
Amnd, the computer is currently, apparently, not rebootable, due to
the confirmed initramfs bug.
