Interesting, The symbolic links on the old drive -still used by the DB- look like windows' shortcuts to parent folder, while they are empty folders in the copy of the database I have on the new drive... When I do a plane copy of those links on another drive I also get the same empty folders. I am getting closer to the initial problem, and closer to the solution! Maybe an image backup of the drive would have done the job properly instead of using a plane copy?

They possibly still point to the old drive. I guess you have to correct them per hand before starting the moved DB. regards, Marc Mamin ________________________________________ Von: pgsql-general-owner@xxxxxxxxxxxxxx [pgsql-general-owner@xxxxxxxxxxxxxx]" im Auftrag von "Daniel Begin [jfd553@xxxxxxxxxxx] Gesendet: Montag, 11.

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 the old 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, and it has worked, but I use linux which is much simpler, and just did an stop / cp / change pgdata / restart, I suppose windows must have comparable ways.
