I attempted to use Dell DataSafe Local. It told me the Recovery Partition was missing or corrupt and it could not perform a backup.  In Nov 2010 I had to do a clean install through the guidance of a Dell technician.  How do I get the Recovery partition back or repaired?  I contacted Dell support today but they apparently could not understand why I wanted to do this since I could use Windows Backup.  Is there anyway to get the Recovery Partition back or repaired?

In looking at Admin Tools->Computer Mgmt -->Disk Mgmt I find the Recovery Partition listed, and the system says it is "Healthy (System, Active, Primary Partition).  I also find the following file is missing:  C:\dell\Image\Factory.wim  How or where do I find that file and get it back on my system. And, will that be sufficient to get the system to use DataSafe Backup?
