A serious problem and I have no solution for it. may I have your help!
on a WD600 hard disk.after working with partition magic,
I face the problem shown in the following picture:
[My HD is Disk 2]

How come?
first I was deleting a partition to make it unallocated.
but before I did I made it hidden!
of course it is unsafe!
Any way after I made this fool I face the problem and I have to solve it.
I tried to format the hard. I face the following message:

so what?
I found out the {BAD MBR} in the formating box.
so may the Master Boot Recored is corrupted and need to be fixed.
I tried to use Fdisk command under DOS but the problem that is while I boot from a boot CD.
My pc is suddenly stops and does not continue to the DOS command it stops at a BOOTING FROM CD:..

I need to fix my MBR but I can't reach the DOS command.
when I get my HD put of PC and Boot from a CD it reach the DOS command as usual with no problem.
which means that it is a fatal mistake in my HD.
can any one give me a suggestion?
note:
in Partition Magic there are no active commands,
except the shown in the image follows:



waiting for a response!!!!

Since it is a WD drive...
perhaps using WD test tools... http://support.wdc.com/download/
it can low level format the drive as well as check it for errors.

I really appreciate your help.
Thank you very much.
I'll try using WD test tools.
I wish I could do something good!
