What happens if one does an incomplete Windows install,

Does that overwrite the data on the disk?

I have recovered large amounts of data from a Windows Server that
later had Linux installed on it. Linux was 100% operational, but it
seems the sectors it overwrote were not critical to the underlying
NTFS filesystem it overwrote. Recovery was rather simple to be
honest.

The point is also, that the drive 'has the intention' to save the info, even if you decide to delete it.
So it will first use all unused space, until it gets to once used space, before it will overwrite the previous info.
I know to get rid of very stubborn worms on windows, i had to format the drive 3 - 4 times, on dos level with fdisk, and create new bootrecords several times..
To demonstrate how persistant sw can be...
After formatting a few times, there might be shreds of info left somewhere, but i do not know if they could be very usefull.

To get rid of using the data, most times totaly overwriting twice just behind eachother was most succesfull in the time there were not such big drives...

Shoot the disk is by far the most enjoyable way to make it useless.. ;)
