I have a new PC (actually had it a few days but have been too busy to hook it up) and will be keeping the OS on one drive and the rest on a 2nd drive. I was under the impression that when you set a PC up like this only the OS (that is Windows) is on the smaller drive and everything (data and applications etc) are on the larger drive. When I picked up the PC the other day I mentioned this to the fellow who built it and he said that the OS and applications go on the smaller drive and only the data goes on the larger drive. This does not make much sense to me as I believe that in most cases its the programs that that take up most of the space on a drive (after the OS of course) and not the data. Also, I thought/think that there is not much benefit to having the OS and apps on the same drive because if you need to reinstall the OS you will also need to install all programs as well. I thought/think that if the apps and data are on a 2nd drive then they can remain unaffected by a system re-installation. Of course much of this is not a big deal as I regularly image my drives and will continue to do so but once I am doing this I figured I may as well do it properly. Oh yes, the fellow I was talking to about this said you want to keep the apps and the OS "close" to each other as that makes the system more stable. In fact, he said that the apps become integrated into the OS in a sense and putting the apps on a 2nd drive was asking for problems. Any guidance in this area will be most welcome and if there is any good info on the net you would suggest I check out please post a link if possible. Thanks.
