You could install it in any of them but reading between the lines none of
them are really satisfactory. You need some elbow room on your disks for
programs to run comfortably and all of those drives sound pretty close to
full. I like to see AT LEAST 30% of the total drive space left free on
disks used for the OS and program files - you can let it drop to less on
drives used purely for data file storage. I'd seriously consider adding a
new 'F' drive, perhaps an external drive such as USB or Firewire, and move
as many data files as you can to it from your C drive for sure to free up
room and perhaps from D and E as well. If you don't have a lot of data on C
that can be moved - what's there now is already mostly OS and program
files - then you seriously need to think about replacing it with a drive
that is at least 3 times the size of the one you presently have. Luckily
drives are getting cheaper than dirt these days - you can get a 500 gig
drive for just a couple a hundred bucks.
