As others has noted, use of dd with seek etc. will do most. I have made list of data recovery tools on Debian. http://www.debian.org/doc/manuals/debian-reference/ch10.en.html#_data_file_recovery_and_forensic_analysis This may help later. Anyway, your harddisk may be faulty. It sounds like to get new one. If I were you and I have minimum budget and hardware (I mean no extra PC), I will go buy new SATA disk and external SATA/USB kit. 1. Buy 500GB SATA at below $100 (160GB below $50) This should be enough space. 2. Do fresh install. (Both NT/XT and Debian) 3. Put old disk on USB box and work on data recovery.
