Disconnect the old drive, connect the drive you want to search thru.
Download any DOS bootdisk
Put that in your computer before you start it up. It should come up a black screen with white text.
Type in: cd C:\
That will take you to the beginning of the drive..... After that type in:dir
it will give you a list of all folders/files in the C:
If you want to go into a specific folder type in the C:, for example C:\windows
when you in the main part of C:\, type in cd windows
Also if you use the "dir" command, the list of folder might be too long to fit on one page, so when you use the dir command somethimes you might have to pause/break the list on the keyboard. The button is by the "num lock light"
