A friend told me to do this.... Divide your drives/partition into this system the next time..... Drive C: Programs - Use to store all program files (would be nice to dedicate one solely for Poser if you have more than 10GB of poser stuff). To figure out how large of a space you need for this drive... it's 3X the amount of space your programs are consuming now. 4X if you're planning on installing more programs. The reason drive C: is for programs is that most software require a C: drive installation. However, if you install Windows on Drive D:, some programs will refer to drive D: to install to. Drive D: Windows OS - this drive is soley for Windows... you'll need a minimum of 4 GBs...but if you store stuff on the desktop alot, you can create shortcuts to drive E: or make this drive bigger. Drive E: Data - Store all your changes and data here so you'll only need to back this drive up. Drive F: Virtual memory (this was my idea) 4GB limit (you can arrange a 1 or 2 gigabyte swap drive but no greater). It's better performance if this is a seperate physical drive. If you use Photoshop, this is an ideal swap drive. Drive G: Backup drive for Drive E: Should be the same size. This allows all drives to defrag 100% faster. If a crash occurs, your PC doesn't go buttom up. Your PC will back up faster Any programs can be easily fixed... such as reformat, windows reinstall, etc.
