Is it possible to partition an existing drive without wiping it? I would like to partition the empty space on an 18 GB drive which currently is not partitioned and reformat the new partition in FAT32 while retaining the NTFS and data on the remainder of the drive. Is this possible or should I just backup my data and repartition the whole thing?

No problem. You need a utility that will repartition. I use Digtal Dolly.
You will need to download it to a folder on your computer. It will have to be unzip in the folder. You will need to burn the files only to a CD in .iso format. This will make it a bootable cd.
It will now boot to a Linux based GUI. Each window have a help page. It does not have requirements to run since it has it's own OS.
But you have the right idea..

BACKUP BACKUP BACKUP!

Better safe than sorry.

Many thanks! :thumbsup:
So this can't be done from the Disk Management Console in WinXP?:flowers:


Another question: once I reformat the new partition in FAT32, I plan to install Win98SE on the partition to run my older, non-XP compatible programs. When I'm operating under WinXP (with NTFS) will I be able to access the FAT32 partition and conversely, can I access the NTFS partitions under Win98SE?

No you can't not use NTSF (NT,XP) system under a FAT32 (9x,ME) system. I believe XP can use FAT32 files, but I'm going to defer to another member to say for sure.

Yes you can format your disk with FAT32 and Windows XP will run fine. The only real useful application for this is multi-booting, ...which you're doing.

If you have unallocated space on a drive I believe Disk Management Console can partition that for you. It cannot partition off free space already part of the boot partition i.e. shrink the boot partition - that's what you would need Digital Dolly for.

When I'm operating under WinXP (with NTFS) will I be able to access the FAT32 partition

Yes, no problem.

conversely, can I access the NTFS partitions under Win98SE?

No, it will be invisible.

Remember you need at least 20% free on a hard drive for the OS to work properly. 18gb must have about 2gb for windows to function, drfrag, restore points,..

Please bear in mind that the oldest OS needs to be on the first partition. Disk Management is not capable of moving the partitions around. For that you will need digital dolly or partition magic.

Dual booting can be fun, just don't try and open both partitions at the same time LOL messes up the boot loader something awfull.

I use two hard drives on my computer. Windows XP currently resides on the Primary Master along with the majority of my programs. The Primary Slave houses several hundred MP3's, documents and assorted files (and is the drive I wish to Partition and install Win98SE upon.) Both are single partion drives (i.e. the partition encompasses the entire drive.) I also use the PS for the WinXP pagefile.

How do I determine which drive/partition is the 'first' one? :thumbsup:

The first partition is partition 0 on drive 0 on IDE channel 0 which will be the one you are booting off now, i.e. the C: drive in Windows XP.

You have made some contradictory statements when describing your drives -

Both are single partion drives (i.e. the partition encompasses the entire drive.)

an 18 GB drive which currently is not partitioned

I would like to partition the empty space


It may help if I clarify some of those terms with my own (rather rough) definitions:

Drive Space - the practical capacity after a drive has been low level formatted.
Partiton - a contiguous portion of the drive space that will contain a volume.
Unallocated space - Drive space that is not assigned to any partition.
Volume - a logical drive created by formatting a partition. Allocated the well known letters C:, D:, etc. by the operating system that uses those volumes.
Free Space - unused storage capacity inside a volume.

Acklan's 20% rule applies to volumes not to the physical drive e.g. there is no problem with having Windows XP in a 18GB volume with at least 2GB free space on a 100GB hard drive. The other 82GB can be allocated to other partitions or they may be unallocated space, either way they will have no effect on the way XP runs.

Have a look at this MS article on dual booting:
http://support.microsoft.com/kb/306559/EN-US/#i

dannyboy 950 is quite right, if you want to dual boot then Windows XP has to be installed last so you would basically have to backup and reinstall your entire system to achieve that. One way around that would be to use removable drive cradles which would mean you could only access one drive at a time, or just thinking out loud I've seen USB external hard drives made bootable which may be a way around reinstalling XP. :thumbsup:

Comments from people who have used external bootable drives?

Could he use a ethernet single drive NAS and network boot to it via PXE?

Why do I keep getting this vague memory of leaveing the last 640MB of a drive unalocated/used or some such.
Something in the cob webs about enough space to load fdisk and other files to be able to wipe and repartition or somesuch thing LOL Funny how the mind wanders when ya gets old. LOL
