Missing files after copying a hard drive - W95

I've been given the task of converting an old dBase database app running on W95 into an Excel spreadsheet. I was given the entire hard drive from a PC to extract the data from. Since I wanted to return the drive the first thing I did was copy what I thought were the entire contents of the disk onto a hard drive of my own.
When I looked for the data I couldn't find it. I then installed the hard drive and booted from it and noticed that folders such as "My Documents" and "Profiles", which I couldn't see on my copied version, now appeared. I also found the data located (oddly enough) in the My Documents folder. My question then is this:

Surely, if I copied the entire drive, I should have all the data on the original drive in the new location. Where does W95 store these system folders? I've looked in the Windows and Windows/system folders to no avail. What am I missing?

Thanks.

 

and by what means did you copy it?

 

Um, nevermind. I went back and took a closer look at the original. Turns out there was a second partition I overlooked. Sometimes I wonder why I'm in this line of work...

Yours truly,
