A request before solving it:

Dear Student,

This is very easy assignment which requires only the implementation of a given scenario. This implementation will build your understanding of real mode and protected mode limitations more clearly. So, do not paste your solution from any kind of source. Just do and describe the solution in steps if possible. Otherwise describes the reasons of No answer shortly.


Question:                                                                                                                               Marks 20     


Ahwas installed 64 bit operating system on his PC. Unfortunately, his system crashed and could not boot even in the safe mode. He has two equal partitions of his 120 GB hard drive. He has an important data on his secondary partition. He has a DOS bootable USB drive with FAT16 structure. Is it possible for Ahwas to access his important DATA from hard drive and copy to USB drive through available DOS bootable drive? Give logical reason for your answer.


Note: Google the different possibilities for the given scenario assuming that it happen with you. Implement all founded possibilities on your system then suggest a feasible solution for Ahwas within steps. You also can use any other utility within the scenario limitations.

RaJa AhMeD sahb, ye sub iffi(Mcs*4) k drame hen, dont take tension

Ahwas ko chahai tha k data or operating system ko separate rahkty tak k humy itni tension na milti aik assignment jo sirf 5/3 = 1.66 marks ki hai in the final result...  

anyhow after searching on Google i think answer is yes but must have any utility program for this purpose and storage capacity of USB must be not less than 256 MB. The connected USB device must have FAT16 or FAT32 file system. If NTFS file system is installed on the device, you are required to format it in FAT16 or FAT32.

we can access with CHS for First 8Gb Data and Then Convert CHS to LBA 32bit width for 2048GB data access and LBA 64bit width we can access data 8 billion tbs of data.
