I seem to have a problem concerning my one hard drive. I am unable to reformat or repartition it using a program such as Partition Magic, and according to FIPS, I have an overlapping partition. How is that possible and can I in any way fix it?

I do not have a problem losing all the data on my hard drive since I am planning to format it anyway, so any suggestions is welcome.

Maybe a silly question (since you're familiar with FIPS) but have you tried DOS fdisk?  It should allow you to remove any partitions, even ones it can't recognize (Ext2, NTFS, etc).  Or you can check with your drive's manufacturer, they generally offer utilities that will let you erase the drive completely.  IBM (www.storage.ibm.com) has a tool that will perform tests, and optionally remove all partition information from a disk.  I believe Maxtor, Seagate, Quantum, etc also have these tools.  What brand is your HD?

I have an IBM drive, so I will go and see if I can get that tool you are reffering to. I have tried FDISK, but it won't even "see" the partitions contained on the drive.

Also you may try Gdisk, is part of Norton Ghost. I have erased DOS and Linux partitions with it including overlaping partitions or if you have Linux you may try Disk Druid.

Are you using any kind of disk managament software?  Like EZ-Drive, or EZ-Bios, ect

What does FDISK see? anything at all?
any non-DOS partitions?

if it see any non-DOS partitions then remove them and see if you can now make new partitions.

FDISK does not see any non-DOS partitions, and no, I am not using any disk management software

Go find the Ranish Partition Manager.  It's free (might be shareware now, not sure).

http://www.users.intercom.com/~ranish/part/

How you got the overlapping partitions is a good question but I would suggest a partitioning tool you have used has not done it's job properly.  I have seen this occur on a Linux installations (mine actually).

I used Ranish to delete an offending partition and straightened the mess out.

NOTE  Be very careful in what you do in using such a tool as Ranish as you can totally stuff things up.  If you are famaliar in using fdisk and fips you should be OK.

Personally, I've had problems with Partition Magic - You might want to consider buying Partition Commander - when Partition Magic gave me errors repartitioning my notebooks' hard drive, I bought and downloaded Partition Commander and it worked beautifully.

Download to a diskette:

 ftp://ftp.powerquest.com/pub/utilities/partinfo.exe

and run the 'partinfo' command after booting MS DOS
(or a Windows 95/98 "boot" diskette),
and cut-and-paste the output into here.

Or, reboot and enter BIOS-setup.
Use 'auto-detect IDE drives',
and choose any of the options *NOT* marked with the '(y)' marker.
Save and exit from BIOS-setup.
Then, when you boot from diskette,
use 'FDISK' to create a partition ("any" size will do).
Shutdown, and reboot, and use 'auto-detect IDE drives' again.
Choose the option which was suggested the *FIRST* time.
Reboot and use 'FDISK' to create the "desired" partition(s).

I've had this problem before, and FDISK won't solve it--it isn't powerful enough. If you use a Linux partitioning program like CFDISK it should be able to kill the dodgy partitions so you can start again from scratch.

Andy shouted:

> YOU CANNOT HAVE OVERLAPPING PARTIONS

But, since several tools have confirmed that the author's hard-drive does, how can the overlapped partitions be removed?

Over to you, BASS2K1, and tell us which of the above suggestions you have tried.

Hey, 'microsoft', your lousy DOS based fdisk program is notorious for not being able to handle partitions it doesn't understand.  Tell your programmers to rewrite it, and properly this time.  Yeah, right.

bass2k1,
I haven't seen that you've tried the Linux version of fdisk.  You haven't mentioned it either way, so in case you don't know linux fdisk, here's a step by step:

Download rawrite.exe and bare.i from here:
http://download.sourceforge.net/pub/mirrors/slackware/slackware/bootdsks.144/

Then get color.gz from this directory:
http://download.sourceforge.net/pub/mirrors/slackware/slackware/rootdsks/

Run the rawrite program.  It will ask for the name of the file and the letter for the floppy.  You'll need two floppies, one for bare.i and another for color.gz.  Run rawrite once for each of those.

Boot from the bare.i floppy.  Press enter at the opening screen because you don't need any extra options.  Then wait as the first linux boot floppy takes a few minutes to do its thing.  Put in the color.gz disk when it says to put in the root disk.

Type the word root at the login prompt.

At the linux commant prompt which is a #, type:
fdisk /dev/hda
and hit enter. (assuming that the hard drive in question is your first disk.  If it's the second disk, use /dev/hdb or /dev/hdc for the third, etc, etc)

Then hit ?.  You'll get the linux fdisk menu.  The instructions from here are pretty straightforward.  'p' prints the current partition list.  'd' deletes a partition.  'n' makes a new partition.  Use 'w' to write you changes to the disk and quit.  If you're going to be using Win-something on this disk after this hopefully fixes it, use DOS's or Win's fdisk to make the Win partition otherwise that's a little confusing for new users to do with Linux.

Good luck, and report back,
magarity

Have you tried http://WWW.BootDisk.COM
Grab the boot-diskettes for OS/2 Warp.
The version of 'FDISK' for OS/2 should be much better.

Or, since you've not posted the output from running:

 ftp://ftp.powerquest.com/pub/utilities/partinfo.exe

try:

 ftp://ftp.powerquest.com/pub/utilities/ptedit.exe

and just "edit" the partition-information,
to remove/resize the partitions.

If all else fails, I'll purchase the old hard-drive from you.   :-)

What's the capacity of that drive?  If it's decent size, I'll take it if you don't want it.

Try with the manufacturer's diagnostic tools /wipe program. That'll kill all partitioning... Or try delpart.exe, a nice little tool. Even old Norton Disk Edit can help, if you know where to begin entering hex 00. Of course you'll have to start again from scratch afterwards.

Here is the page to download the IBM "Drive Fitness Test" (DFT): http://www.storage.ibm.com/techsup/hddtech/welcome.htm#DFT
Use the low-level format utility to completely erase the drive.  If by chance that doesn't work (there's no way it won't, but...), try this:

Copy the following text into a file (call is wipedrv.txt):
---don't copy this line---
a 100
int 13

rax
0301
rbx
0200
f 200 l 200 0
rcx
0001
rdx
0080
p
q
---don't copy this line---
Make sure you have a return after the q at the end.  Now copy the debug program from a Win9x machine (or post if you can't find it, I can email it to you) and boot to a generic DOS boot disk (with debug.exe on it).  Then type:
debug <wipedrv.txt

This will remove all partitions on the drive.
