I was using the "Get Drive Information -Total Size" and "Get Drive Information - Free Space" put them together sort of as a What you got...(on Drive C: only)and What you got left scenerio, it usually works 100% but today I used it on a old office computer with Win95 which had 2 SCSI drive (letters) , and it told me I had more FreeSpace than I did Total Drive Space?? not sure whether it was actually 2 seperate hard drives or just a partition, can there be an error on how it reads free space off the SCSI bus? and............anyone got a SCSI drive to test this on..
