[QUOTE=geno888;2012684]My suggestion is to use the 750GB HDD for data only, and use the 300GB drive for operative systems.
The amount of space needed is related mostly on how many programs you will install on your computer. The operative system by itself doesn’t require so much space.
I suggest to create a 20-30 GB partition for XP. For what I know, there is no real advantage to create a separate partition for programs, but is better (in my opinion) to have all programs installed in C:
It can be advantageous to create the swap file on a separate HDD (not a separate partition of the same HDD), because this can improve its performance.
If you are planning to install Windows Vista in future, then you will need a little more space, but I strongly suggest to install it from scratch, and not do an upgrade. usually upgrades creates a mess. So 50GB should be sufficient for windows.
Because of very often the operative system needs to access the HDD, I suggest to keep the partition you use to burn discs on a separate HDD. In this way, when you are burning a disc the operative system can access the HDD with no risk to cause buffer emptying. I suggest then to use a single HDD for operative system and programs only (both windows and Linux), and store all data on physically separate HDD (not in different partitions of the same HDD).
If you want create a separate partition to store data to be burned, then a 10GB partition should be more than enough.
Because of Windows is rather picky about the boot loader, I suggest to install Windows first, and Linux thereafter. When Windows require to format the HDD, I suggest to create a partition (25-30GB or 50GB for Vista as I said previously, but of course you can choice any size) and leave the remaining space unpartitioned, so you can install Linux in future. I also strongly suggest to install ONLY the HDD where you will install windows first, and add the other discs only when Windows is fully installed.
Linux requires a swap partition, and it is advised to create one. If I’m not wrong, usually the swap partition is created around double of RAM, so you can create a 4GB swap partition. Again, there can be a slight performance gain if the swap partition is located on a physically separate HDD.
Also for Linux, I suggest to store your data on a separate HDD, leaving the operative system separate from your data. This is because if something goes wrong and you need to install again the OS, all your data will be safe.
I hope this can help :)[/QUOTE]
I totally agree with the MOD. I keep my O/S HDD on a separate HDD from my games HDD and data HDD. Just cause of as the MOD said when burning it’s free up the main HDD to do other things and saves the life of the drive more. I have a 20G HDD and 60,80,100,250 and mayber later a 750 if possible to store all my data on. I do use the 80 to keep a ghost image of my main HDD so that I can reboot it and update the programs and the O/S and remake the a clean image. This has saved me on alot of occassion when I did delete something from the main O/S HDD that I wasn’t suppose to or to reghost it back if something didn install right and redo the process again.
