Hi, Can't remember where I got this years ago when I also personally discovered that MS-DOS Fdisk was a weak little creature. This is about the easiest way I have ever found to totally wipe a disk clean, even the MBR, regardless of what software configured it.
Boot your system from a MS-DOS floppy disk. Type: debug (press enter) Type in everything between "<" and ">" exactly as shown, but do not type the "<" or the ">" or anything outside the "<" and ">". -<F 220 L1000 0> (press enter) -<A CS: 100> (press enter) xxxx:0100<MOV AX,301> (press enter) xxxx:0103<MOV BX,200> (press enter) xxxx:0106<MOV CX,1> (press enter) xxxx:0109<MOV DX,80> (press enter) note: use "80" for first HDD, "81" for second HDD, etc. xxxx:010C<INT 13> (press enter) xxxx:010E<INT 20> (press enter) XXXX:0110(press enter) note: this is very important, don't skip -<G> (press enter) Program terminated normally Now, reboot system and use Fdisk to partition and prepare for MS-DOS. I am 99.9% certain I have not mistyped anything (I checked it 3 times), but just in case I will utilize the standard disclaimer: I accept absolutely no responsibility for your use or inability to use any of the above. You do so at your own risk. Bill P.S. Undocumented command: fdisk /mbr (press enter) will remove the Master Boot Record > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED]]On Behalf Of David Talkington > Sent: Tuesday, April 23, 2002 3:05 PM > To: [EMAIL PROTECTED] > Subject: Re: Format RH 7.1 PC for WIN98 > > > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > Ross Cooney wrote: > > >I was able to get 2Gb of space out of one of the Linux > partitions using > >FDISK, but I cant get the other partitions back...How do I > get the RedHat > >partitions back so I can format for Win98? > > Microsoft's fdisk is a crippled little beast that only understands > Microsoft partitions.
