How can I revive an NTFS formatted hard disk that got its MBR corrupted?

Question

I got two harddisks on my PC

- one is FAT32 formatted and the other is NTFS
- each has an XP operating system
- I use NTFS formatted disk as my priority because it can
hide my personal files effectively.
- I wanted to reinstall the XP OS on the NTFS formatted disk
to refresh my system and remove unnecessary changes created
by other users.
- I switched to my FAT32 formatted disk and deleted
the XP OS files including the Program Files and the Documents
and Settings on the NTFS disk, I left my other important files.

The Problem

After I rebooted my PC still using my FAT32 formatted
disk, the NTFS disk won't appear on the local disk
of the Explorer anymore. But the status is 'working
properly' as seen in the Device Manager.

I tried everything, including the Seagate Diag but
the software suggested to have my disc replaced after
it saw the Master Boot Record was corrupted.

Answer 1

There is a command called fixmbr you can use from the Windows XP recovery console. This will over-write the master boot record (MBR).

Answer 2

Insert XP CD select Repair when asked.

Type Fixmbr.

Answer 3
