I am looking for a hardware/software solution to clone NT disk. Since one
week have I tried , the Windows NT system from a 4Gb toshiba notebook copy
to a new 20Gb IBM. I used DriverImage 4 and PartitionMagic, Ghost, but
after the clone, the system can not be used. The Notebook can detect the
20Gb disk. And Windows NT system is on a 2Gb ntfs partition. On the NT
system is already installed ServicePack5(with new Atapi.sys).

Can anybody help me?

Thx!

This should work, _provided_ you keep the destination partition below
7.8GB, and ensure it is the first partition on the disk. Also remember
that you will have to copy the MBR, as well as the actual partition
(running the install disks, and selecting the option to repair boot, will
copy this). If you are attempting to expand the partition beyond 7.8GB,
then you are running into an inherent limitation of NT4.

In article <9l5n3q$50l$1...@sun27.hrz.tu-darmstadt.de>, zhi...@gmx.de says...

The problem is the infamous 8G limit. NTLDR, which loads NT, does NOT
understand the new extended Int13h routines needed to access beyond 8G. If
any system files required for bootup extend beyond 8G, the boot will fail.

The easiest 'fix' is to keep the boot partition under 8G. Then create a
second partition to fill up the rest of the disk. You will need to be up
to Service Pack 4 or newer in order to access beyond 8G after NT boots up.

Another, more difficult way around it is to try this before copying:
Make certain you are at SP4 or newer.
Find ATAPI.SYS (typically in C:\WINNT\SYSTEM32\DRIVERS?) and copy it to
C:\, then rename it to NTBOOTDD.SYS.
Copy C:\BOOT.INI to C:\BOOT.OLD (as a backup)
Change the attributes of BOOT.INI, and remove the READ ONLY attribute.
(Just right-click it in Explorer and edit the properties.)
Open up BOOT.INI in Notepad or other TEXT editor.
Find your regular boot line below [operating systems], which will look a
bit like this:
multi(0)disk(0)rdisk(0)partition(1)\WINNT="Microsoft Windows NT 4.0"
Copy that line, or retype it just below it, but change multi( to scsi(.
Also, change the text between the quotes so that you can tell the
difference (add [scsi] to it or something like that.)
Save the file.

The scsi() syntax just means that NTLDR will first load NTBOOTDD.SYS
instead of using the BIOS. The driver loaded is normally for some SCSI
cards, but can actually be for anything. By creating a separate boot
entry, you have the choice of using the new method or old one, in case
something goes wrong.

When you try the new way, be patient. I tried this once, and there is a
long pause while the driver loads. Once you clone over to the big drive,
you can then use the newer method to boot up. If it works, you can then
edit the line below [default] in BOOT.INI to match (probably just change
multi to scsi again.)

Sure, use Powerquest's Drive Image.

You should be able to do it (I have used DriveImage many times). The problem
here is with NT4.0 limitation of 7.8 Gig on the bootable partition.

BTW, Win2K does not have this limitation.

I suggest you create two partitions on the new drive:

one (C:\) about 7.5 Gig, and another (D:\) the rest of the physical drive, then
clone the original drive into C:.

I usually partition my drive into three:
1) (C:) Operating System and utility software (Anti virus, Norton etc...)
2) (D:) application s/w
3) (E:) my own data files

This way I only need to backup drive E:

Hope this helps,

Yes, i know, NT has the system Partiton limit 7.5GB. But the new HDD has a 2GB system partition, it should has not this problem. But ...

In that case, it appears you are trying to clone a 4GB partition onto a 2 GB partition.  You will run into trouble cloning to a smaller partition, even if the actual used space on the disk was less than 2 GB.  Make your new system partition 4GB, and everything should be fine.
