tig, he may be asking about the OS recovery partition.
richp413, the computers I have seen with a hidden recovery partition have a sheet in the documentation that explains how to create recovery media. You can also do a full clone of the hard drive, which will capture even the hidden partition using a program such as Ghost.
I'm guessing that's what you are asking about, that's really the only time one would have a hidden partition.
Yes, that is exactly what I was asking. I did not find any documentation about creating a recovery media. It seems the computer company's have found another way to save a dime. They send no back up with laptops. Thanks for your help. I will look for a clone program.
