What is the file size of the Data.fs file? Did you try stopping zope, removing the Data.fs.index file and starting it again?


Apologies if this is not the right forum

I have a corrupt Data.fs file and would appreciate some help recovering
data.

Zope 2.4 (still in the Stone Age)
OS: Windows 2003 server
Runs as service

The problem was first noticed yesterday on trying to save a web page
after making changes. Received the following error message.
IOError: (0, 'Error')

I tried the following

Restating the Zope service with the following results
- Starts and stops immediately

Start the Zope service using "start.bat" get the following
