You can try fdisk/mbr. There is also a Debug script that'll do the trick. I'll try to find it.

Edit: Found it.
There are times when Fdisk can not delete the partition table.... But a small debug script will do the job.

The following debug script can be used to clean the master partition table. After running this script, the FDISK program should be used to create partition/partitions.

1. Boot from a MS-DOS version 7.0 (Win98 or Win95) formatted floppy and run the DEBUG program.
Note - If you want large disk support (Fat32) you will need a later version of 95 or any version of 98.
2. Start debug and Enter the following commands.
Note you are entering a small assembler program.

The machine's responses are:

-F 200 L1000 0
-A CS:100
xxxx:0100 MOV AX,301<ENTER>
xxxx:0103 MOV BX,200<ENTER>
xxxx:0106 MOV CX,1<ENTER>
xxxx:0109 MOV DX,80<ENTER> <-- "80" for hd 0, "81" for hd 1
xxxx:010C INT 13<ENTER>
xxxx:010E INT 20<ENTER>
xxxx:0110 <ENTER> <---BLANK LINE - IMPORTANT!
-G
Program terminated normally
NOTE - Run at your own risk as this is non-recoverable.

hey zho....thx for the reply....but it became a bit of OHT(Over Head Transmisson) for me......i was able to do it by Ultimate boot cd....but now i've a new problem......i'm not able to format my HDD in FAT32 file system.....its not allowing me.....i even tried through recovery console n tried to run the command at command prompt, it did format but the XP setup is not able to recognise is at all....it gives me a option to format in NTFS before installing.....pls help....i also wanna know the difference between NTFS and FAT32.....advantages & disadvantages....i believe that NTFS has too much of security n is not so stable....but FAT32 is stable n reliable......advice
 
Well, I'll let the experts give the gory details; but to keep it simple and sweet - fat32 is the older file system used in win95. 98 and Me. NTFS is used in XP. It supports bigger drives, has more fault tolerance, and is MORE reliable. Only thing is, older versions like 98 or Me do not recognise ntfs.
 
FAT32
- Less Secure
- Not compatible with old days Windows-NT versions
- More prone to disk errors

NTFS
- Secure
- Faster access then that of FAT32
- Disk quota can be fixed
- more stable then fat32

You can always flash samsung drive`s MBR with HUTIL (Software provide for making partitions), do check for the same option with the relative manufacturer, if not available... try this one
