Logical and Physical disk drives



Logical disks:

Does it help to partition your 40 Gb C:\ into two 20 Gb partitions (C:\ and
D:\)? If I had an application that only wrote to D:\ (and lets say, for
arguments sake, that the app writes frequently to disk), would the partition
help reduce the likelihood of OS corruption? Would it reduce disk
fragmentation?

Physical disks:

On a related note, does having two physical drives help with the above?
Presumably with file fragmentation it would, but what about helping with OS
corruption?

Thanks,
Alain
