I have a Dimension 2400 and a Dimension 4550. Mistakenly a couple of years ago I reformated the entire hard drive on the Dimension 4550, erasing everything from the hard drive including reset files from Dell. I'm not sure if this same mistake was ever made with the Dimension 2400. How can I find out if all those files are still on the Dell partition, and if so/not, how to start reformat.
