Hi Bob,

There is lots of information, but the main consideration is what is your usage.

Google it

A visit to Fred Langa’s website http://langa.com/index.html may also have some info.

General Use suggestion
Windows Partition - 10GB for your windows partition should be fine and allow windows and programs, assuming you want them on the same partition, mine are on a different partition.

Data Partition - 10-20GB for all your volatile data files, Word docs, etc. spreadsheets, database files.

Music/Images Partition - This would depend on your usage and could potentially be your largest partition (probably the rest of the HDD space). This allows for expansion/resizing of the other partitions, etc.
