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.

yar we can directly access data from it its not issu.

"We Can Access Data Upto 8 Billion gb from dos"

but can we mount the hard dik.

can we boot 64 bit system

You also can use any other utility within the scenario limitations. 

sir na ak point ya b diay hua ha is pa b thori dission ke rlain.then fnal ho jya ga.

ok, lets have fu every body say No. with some logic so sir ko yaqeen ho jay ka bachon nay hard work kia but hard disk access na ho sky our ho be nhi sky gy. 

64 bit operating system means the the partition is in NTFS? confirm this please.

I searched on Internet and found that DOS boot able USB drive with FAT16 can access data from 64 bit windows,

I think Ahwas can access data in this case. but he can access limited amount of data that is not more than of 2GB from secondary partition. If he has to copy some files that are less than 2Gb than i would be possible for him to access it ....

Wot you ALL says ????

 Mohsin Latif bro it is not necessary for 64 bit OS to hv partitions in NTFS you can use FAT32 as well with 64 bit OS

windows use 64bit nfts efat fat32

Linux use ext3 ext3 

ANY TYPE UTILTY BUT it is must usb with fat16 it is not change

i think we can use Backtrack or ubutu linux based operating system without instllation we can run it and copy data from local drive to usb drive easliy...

am i right...

it is not for data compressing task.

read again assignment for clarification.

in 64bits system hardware run on long mode.
