The HDD mounts fine and I can access everything on it as expected, but somehow I can't erase the old partitions within the extended partition even when its unmounted. The only partition I want to have left in the old HDD is the old /home, so that I can make that the /home for the new system.
I've used Linux for quite some time and I'm fairly familiar with its workings, but I'm still just an end user and English is not my primary language (thanks Firefox for the spellchecker...). I understand English well, but I'm at loss when it comes to abbreviations, slang and jargon (hence my stiff language). Additionally I'm not at all proficient in LVM and didn't even know about its existence before I installed Mint 18 on the old computer and was prompted if I wanted to use it, and with some old partitioning problems in the back of my head I was seduced by the description "to make later changes in the partitions easier". The tools I've tried to use is system-config-lvm, Gparted and of course the command line for the snippets here. I prefer GUI's whenever possible.
Gparted shows a single partition representing the physical volumes of the lvm, and only in the information window will it show the logical volumes. So that leaves them unmanageable through Gparted. I guess that's just how it's supposed to be, I've read that Gparted doesn't fully support LVM. To bad for me, for I have some understanding of that interface.

system-config-lvm shows all the volumes, both physical and logical, as expected, but I don't seem to be able to single them out. In the physical view I can see which volumes I wish to delete, but in that view I don't seem to be able to do just that. In the logical view I can edit the properties including deleting (presumably - there is a button for it but I havn't tried it...) but in that view I can't differentiate the root or swap in the old HDD - which i want to delete - from the ones in the new SSD - which I want to keep. (Ok, the swap is no big deal, easy enough to replace, but the root!)
I'd greatly appreciate any help!
By looking closer at the numbers presented by the commands pvs and lvs and comparing them I found that I could deduce the size of the partitions I wished to delete, and those where in fact the partitions that where shown in logical view of system-config-lvm. I'm really sorry if it seems like I didn't empty all options before asking for help, but I really thought that the ones shown was some kind of conglomerate of all the physical volumes with the same name. After all, where else would the ones from sda3 go otherwise? But since it was only the ones in sdb5, I deleted them. I suppose that it was just the ones that were in an unmounted drive and therefore editable? For why else would not the ones in sda3 be visible? If someone have another suggestion, please correct me - I'm just guessing here...
