Thanks for your reply
However, neither Windows Disk Management or Partition Magic is capable of
erasing a partition completely
It seems like the only erasing activity that Windows Disk Management does is
simply to erase the Master File Table
Partition Magic "Delete and Secure Erase" option does more - certainly takes
a lot longer - but it does not remove Windows Boot Sector code when the
selected partition to be deleted / erased was a Windows XP partition
Here is one way you can test to see if an application / tool is capable of
erasing a Windows Boot Sector code
Take a fully erased hard drive (written to zero's) using an appropriate DOS
application / tool and partition the hard drive into four (4) primary visable
NTFS partitions using Partition Magic (DOS)
Boot into each partition by changing which drive is Active - use Partition
Magic to change the Active partition
On each boot, you will probably only get a blinking cursor - no error message
Next, insert your Windows XP installation disk and use said disk to boot
into "Windows Recovery Console"
Use the "FIXBOOT" command and write Windows Boot Sector code to all four
partitions
Reboot the computer into all four partitions using Partition Magic DOS to
change the Active partitions
You will now get the following error message on each boot
"NTLDR is missing
Press CTRL + ALT + DEL to restart"
Next, use your Windows XP installation disk and install Windows XP on the
first primary partition
From the first partition, if you attempt to delete one of the other three
partitions using Windows Disk Management and then recreate the same partition
using same Windows Disk Management and then boot into said deleted /
recreated partition by using Partition Magic DOS to change the Active
partition, you will get the same error message which means that the Boot
Sector code was not erased during said deletion activity
Note: Windows Disk Management does not write a so called complete Windows
Boot Sector code to a partition when it formats a partition - A complete
Windows Boot Sector code is actually more than one sector -
You can test this by doing the same setup
Create four fully erased primary partitions
Install Windows XP in the first partition
Use Windows Disk Management to format the other three partitions
Boot into each partition, using Partition Magic DOS to change the Active
partition
You will not get the previous mentioned error message
"NTLDR is missing
Press CTRL + ALT + DEL to restart"
which means that Windows Boot Sector code was not written to said partitions
during Windows Disk Management formatting process
All of the above is also true if you attempt to use Partition Magic (Windows
or DOS version) to delete / erase a Windows XP partition - it doesn't erase
the Boot Sector code
