I need to recover my autocad files. Every time I try to open a .dwg file it says "drawing file is not valid".

My HDD crashed and I restored my data using a recovery utility and since then my autocad files cannot open and giving the above messages.

The file sizes are correct. Could anyone direct me to a tool fixing corrupted files. Or a method to open the existing files. I tried to open the .bak and .sv files but they are having the same problem.

To start the RECOVER command

From the File menu, choose Drawing Utilities > Recover.
In the Select File dialog box, select the file to recover.
Choose Open.
The drawing is scanned, and an attempt is made to repair any errors found.

One method for recovering corrupt drawings is to insert the drawing into a new blank drawing. However, when you use this method your layouts are not recovered.
Solution

You can use AutoCAD DesignCenter to copy layout information that otherwise would be lost.
After inserting the corrupt drawing in AutoCAD 2000, save the new drawing with the inserted objects.
Select Tools > AutoCAD DesignCenter, then select the Desktop icon.
In the DesignCenter tree view, navigate to the corrupt file and select it.
Click the plus sign (+) in the box to the left of the drawing icon and select Layout Below.
If the drawing is not overly corrupted, the existing layout(s) will display in the contents of the DesignCenter window.
Select the layout(s) and drag them into the current drawing.
To remove a layout right-click on it at the bottom of the AutoCAD editing window and selecting Delete.
You can also use this procedure to restore External References lost as a result of file corruption.

Important: Run the AUDIT command after adding each layout, in case the newly inserted layout was originally the cause of the corrupt drawing. Also, save your drawing after each AUDIT command so that if one layout does corrupt the drawing, your losses will be minimal.

I tried the inserting method but still it was giving the same message "drawing file is not valid". I need a different method. I have tried all that is there by AutoCad support site and nothing worked.

Try reinstalling AutoCad, sounds more like the file type can't be read rather than a corrupt file

I have tried all of the above, but still no use. The built in recovery option of autocad is not fixing the problem.

I need a third party software that attempts to fix corrupted/damaged files of autocad.

Have you tried transferring the files to another location (different installation)?

The problem still seems to be a corrupt file which AutoCad is unable to recover.

Dear Sirs, I tried each method listed here but was unable to recovermy dwg files. I was burning files to the CD and was unable to complete the funtion becasue the files were to large to copy to the disk. I discontinued the process. I removed the file copy icon. I think this caused the file to be invalid. I did not know that the dwg files would not open after what I had done. Is there any possible means of correcting the invalid file so they will open. Is there a program that that will fix the problem.
