Help opening a file with incorrect or corrupted information

Using AutoCAD 2010.

Can anyone give me some information about opening a file that may contain incorrect or corrupted information?

I try to open a file, it shows a preview in the open dialog window, but when i push the open button, I get the following message:

Unable to open this drawing.

It contains incorrect or corrupted information.

The RECOVER command may be able to restore undamaged material from this drawing.

When I try the recover command on the drawing, Autocad shuts down part way thru.

Any help would be greatly appreciated.

Thanks,

Bert

Sometimes >>not always

Thanks for the suggestion, but it didn't work. Told me it may need to be recovered.

What version was the drawing saved in?

The Partial Open helped me once or twice. Also it worth to try importing the drawing in an other software that can open DWGs, like SolidWorks.

Have you tried using DWG TrueView?

ehm 'microstation'

It was saved in 2010.

I tried the partial open option. Couldn't get it to work.

I don't have access to Solid works.

Thanks for the suggestioins.

Have you tried using DWG TrueView?

I tried TrueView also and Microstation.

The only other option I can come up with is that there is some kind of security setting on it.

We are going to contact the originator of the drawing and hopefully they can help.

Thanks to everyone for all the suggestions.

If it had security on it you would get a vastly different message.

Can you post the file and let someone here have a go at it?

I can't post the file. We are strickly prohibited from that.

Thanks for your help.

One last try:

Open a blank drawing and INSERT the bad drawing as a block.

Using ACAD 2010

Resently changed from 2005

OS - Windows 7 Home Pre, 64bit

I have had this very same problem that arose only days ago. I can open these files in 2005 just fine, yet if i try to open in 2010 I get that message. But only on "select" dwg's, not all.

This is an example of one of the drawings that I get that message with. Any help would be great! Thanks in advance.

P3.0.dwg

I got the message to recover and it recovered fine for me....you should open in AutoCAD 2005 and run an audit.
