Read the experience of Nicole
here who accidentally deleted the small OEM Recovery partition during Clean Reinstall to Samsung, then was not able to get Elan Touchpad and Cam software working correctly. Samsung told her the software to make them work is accessed via the Recov partition and it could not be restored.
This all sounds very shady because the software posted on website is supposedly is the same software stored as apps on Recov partition, although there also remains the option then to run full Factory Recovery which appears to be their convoluted solution to how to use the clean reinstall DVD
they provide.
Research shows that only using the DVD backup method for Recovery (not external HD storage) will reinstate the Recov partition if it fails or is deleted.
All in all, the worst ever reported clean reinstall experience with Samsung whose abysmal tech support bullied Nicole until the retailer took notice and replaced the machine.
To add to the outrage, they provide a Windows 7 Reinstallation DVD!
