It's generally a good idea to downsize C: to 20-30 GB,
as the comment above wisely suggests: this makes
creation and management of drive images much easier,
particularly when you are required to restore a drive image.
Then, the long format in Windows Setup won't take all night,
and it will check each sector in that C: partition, so that
bad sectors can be flagged and known to the OS.
Later, after the OS is installed AOK, you can partition
and format the remainder of that HDD e.g. D: or E: etc.
as a data partition. With this setup, you won't lose data
stored on that data partition if/when you must restore
a drive image file and consequently overwrite C: completely.
