I am looking for a script that will put the drive letter and amount of free
space on that drive in a spreadsheet in 2 separate columns.

Sometimes it has 1, 2, or 3 drives and sometimes the drives don't start with
the letter C.

Also, I would like the script to put the current page size and the last date
and time it rebooted in the same spreadsheet.

Is this possible?
