BD removed

Hi there,

I need some help. We have a Web application connecting to a postgresql
8.2 database on Windows Server 2003. According to the log, we logged on
the server using a remote control desktop, after uninstalling Tomcat we
installed a new Tomcat version. After that, we shutted down the
Postgres service and restarted the service again.

The problem is that the folder where the tablespace of the database is
placed has been removed.

This is the log:

Alguien sabe que ha podido pasar y como podemos recuperarlo.

Does anybody know what happened? and how can we recover the folder?

Thanks in advance!
