RECOVERING DWG FILE?

Question

my computer got infected and in repairing it had to back up my files, clean the hard drive and reload the files.
in the process some of my autocad dwg files have been corrupted/ damaged. when i do a search of my hard drive, these files show up but when i click to open them i get a message reading
:"the drive or network connection the shortcut 'SITE.dwg.lnk' refers to is unavailable ..."
anyone knows how i can recover these dwg files

your comments and suggestions are appreciated

Answer 1

Drawing Recovery Manager (command DRAWINGRECOVERY)

Displays a list of all drawing files that were open at the time of a program or system failure. You can preview and open each drawing or backup file to choose which one should be saved as the primary DWG file. After a program or system failure, the Drawing Recovery Manager opens the next time you start the application. Drawing Recovery Manager displays a list of all drawing files that were open. The System Variable RECOVERYMODE controls whether drawing recovery information is recorded after a system failure and whether to show the Drawing Recovery Manager or not.



If you want to help yourself, Autodesk and other AutoCAD users make sure to send in any errors to Autodesk when you see the Customer Error Report dialog box (CER).



Finally a solution that sometimes helps if AutoCAD cannot fix the problem is to try to fix the drawing in another program that can open and save DWG files. The more users having the similar problem the better chance it will be fixed in a service pack or future version. Eventually you might get DWG Repair Kit saying the problem is fixed.

If neither of the above options allow you to open the DWG, move on to the next set of steps.



These steps can be tried one at a time. Make sure to stop and try to open the file after each one. If the file opens, there is no need to continue to the rest of the steps.

1. Open a blank DWG and run the RECOVER command. Select the problematic file. AutoCAD will attempt to recover the file and open it.

2. Open a blank DWG and run the RECOVERALL command. Select the problematic file. AutoCAD will attempt to recover the file and open it.

3. Open a blank DWG and run the INSERT command. Select the problematic file and see if it will insert. If it does, then run EXPLODE and select the inserted block. Run AUDIT and PURGE commands, and then use SAVEAS to create a new DWG.

4. Look in the same directory where the DWG resides and see if there is a BAK file of the same name. If so, rename the BAK extension to DWG and see if the file can then be opened.

5. Look in C:\Windows\Temp for files with an SV$ extension. If any exist with a similar name to the corrupted DWG file, then rename the extension to DWG and see if it can then be opened.

6. Go to your backup system and restore the file from a time before it became corrupted.

I suggest that you download a data recovery software, see this article
