For Samsung F1 750Gb & 1Tb spinrite HDs.
If you have one of these drives you may get a disc error reported on the
first reboot while installing.
There is a small bug in the firmware that prevents it from booting if you
install to a formatted partition.
I found this the hardway and took 1 and a half days to track down!
The trick is to leave the partition that you intend to install to as
unformatted .
Then pop the win7 disc in the drive and boot from that, choose custom
install and select the Unformatted partition, Win7 will format the
partition and make it bootable at the same time ;D

Hope someone finds this useful
