Ext3 Partition lost

I am writting this message because i managed to loose an ext3 partition by 
responding to a Norton Antivirus Alert . The story goes like this . Yesterday 
as i was working with my Windows 98 Norton Antivirus found that someone has 
altered my Master Boot Record and prompted me for proper action . As i was 
doing nothing that would alter the Master Boot Record , i responded to Norton 
Antivirus that it should replace the Master Boot Record with the original one 
that he knew . But then as i tried to access the ext3 partition on the hard 
disk i couldn't . The disk is an Western Digital 30 GB Hard Disk , who 
supports UDMA 66 on the Primary Master Channel of a Promise Controller . 
At this point i have to say that my motherboard is a QDI one with the i430VX 
Chipset , with a BIOS dated back to 1997 . In the Enclosed file there are my 
attempts to mount the partition in question , an attempt to run the e2fsck 
programm and the error  returned to me , the remaining of the partition table 
of the disk describing the 2 remaining Partitions  and the Boot Messages 
which describe what Linux understand of my controller among with my disk 
configuration . I don't know if that will help but the partition in question 
was a 10240 MB Partition with a block size of 4096 bytes . I guess Norton 
Antivirus hust erased the entry of the partition table and didn't really 
damaged the actuall partition . Is there any way to access my missing 
partition and the data in it ? . Any help would be grattely apreciated 

Thanks in Advance 

[root Christina root]# mount -t ext3 /dev/hde3 /mnt/Data2
hde3: bad access: block=2, count=2
end_request: I/O error, dev 21:03 (hde), sector 2
EXT3-fs: unable to read superblock
mount: wrong fs type, bad option, bad superblock on /dev/hde3,
       or too many mounted file systems
       (could this be the IDE device where you in fact use
       ide-scsi so that sr0 or sda or so is needed?)
[root Christina root]# mount /dev/hde3 /mnt/Data2
mount: error while guessing filesystem type
hde3: bad access: block=0, count=1
end_request: I/O error, dev 21:03 (hde), sector 0
FAT: unable to read boot sector
mount: you must specify the filesystem type
[root Christina root]# e2fsck /dev/hde3
e2fsck 1.27 (8-Mar-2002)
e2fsck: Invalid argument while trying to open /dev/hde3

The superblock could not be read or does not describe a correct ext2
filesystem.  If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
    e2fsck -b 8193 <device>
