I have found on this site and others that the master boot record is located at Cyliner Head Sector of 001 on a HDD. I have been able to read this data using a microcontroller as well as a hard disk editor software. :)

Can anybody tell me how to interpret the data in that location so that I can find the folders and files in the HDD :confused:

Don't know much about exact location of file names etc., except they're not located in the MBR.

A starting point would be the articles on MBR, volume and file structures in the PC Guide:
