Error messages with DGN files

I have a problem with opening some DGN files. I get an error message stating
that the file format is unrecognised, however other files in the same folder
are ok. I don't believe that they are corrupt, does anybody know if there
are any file utilities or anything that can look at files, or fix corrupt
files.
There is a huge amount of work at stake here, any help would be much
appreciated.
I did rebuild my machine (after backing up) but surely this should not be a
problem.

Many thanks

Hello Frank,

If you are using Microstation 95, SE or v7 you can use EDG,
see the administrator quide.

Before you are using EDG, always make a backup!!!!

some usefull EDG commands
verify whole / none
patch wft/a w
patch wid/a w
repair whole

Open the design file in EDG:
use the next command first to check if the design file is corrupt:
v w/n

If you are getting errors you can do the next
p wtf/a w
p wid/a w
rw

to check is the design file is repaired.
v w/n

If you have still error
you could also delete some elements
v w
del

if the element is a complex element
v w
header
del

to step through a file you can use <return>

for better information about Microstation see the newsgroups of bentley
