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     

Question:

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.

ð     Contact through Skype or email for any other query.

BEST OF LUCK

plzz explain how???

yes can run

so tell us

1st read this , can we access the larger size disk

There can various volume with various sizes with FAT12 or FAT16. The number of
entries for FAT 12 or FAT16 are limited then the question arises how can a certain
volume with moderate space and another volume with large space can be managed by the
same FAT system. The answer is that the number of entries might be same but the size of
cluster may be different. The cluster size can vary from 512 bytes to 32K in powers of 2
depending upon the volume size. The above slide shows how the cluster size and the
exact number of required FAT entries can be determined.

There are many tools available In FAT16 to address problems and recover data.If you have a startup failure, you can start the computer with an MS-DOS bootable floppy disk.

yes Haani bebe. but there are questions? 

1.  can MS DOS FAT 16  mount 60 GB hard disk

  . Maximum 2 GB as primery and 8.4 GB in extended mode.

2. can u boot 64 bit system with FAT 16 dos

 

yes  haani  we need to search about these tool so that we clearly told how can ahwaas copy data.

Yar Zahoor Elahi! is assignment ma kerna kiya hai jo hum fat16 aur dos partition limit 2gb he ker rahe hai kuch time sa

if we change the format it will permanently delete the system data
