How big? According to PgAdmin my personal database is about 2TB...
How critical? Well, about a year of work!-)

This is what I have just tried when I got “Could not read symbolic link “pg_tblspc/100589”: Invalid argument”
Considering both drives are identical, could an image backup have done the job properly instead of a plane copy?

I do not think it is that easy. You can move nearly everything, but it will be slow an you are not going to get rid of
theold disk.
One question, ¿ How big/critical is your database ? because all your problems can be solved with a dump/initdb/restore
easily,and if you can leave it doing overnight it is th easier way. Also, I've moved directories across disks before,
andit has worked, but I use linux which is much simpler, and just did an stop / cp / change pgdata / restart, I suppose
windowsmust have comparable ways.
