Sorry but that was the only way I could explain this. I have 2 hdd in my computer both 160g. One is mainly for storage. I recently had a problem where my main hdd was logging on very slow. I am not sure what caused this. I tried to remove some programs and this did not solve the problem.
So I decided to use my storage hdd as the boot hdd and start fresh. But here lies the problem. I would like to run this at full efficiency. I was wondering if I could partition this hdd to have the OS on 15g of space and the programs on another partition. Basically I am trying to get the best results with what I have and have a faster log on time.
By the way I have 3g of ram and my Processor Name Intel(R) Core(TM)2 CPU 6320 @ 1.86GHz (2 Cores)
Bus Speed 1067 MHz
Processor Speed 1.866 GHz
If I understand you correctly with you saying that you were having problems logging on to you machine then most likely it was a windows issue. I'd leave the storage disk as it is and if you want to start fresh, just do a format on the old system drive and re-install the OS etc.
You could always check the drive for problems etc first just in case.
I agree with takenra, that is most likely a Windows problem because logging in is the only slow part and nothing else is the problem. What I would do is backup your computer on your older drive then reistall Windows on the other, then transfer your data back to the newer one.
I would suggest a format of the primary drive first. See if that fixes the slowness problem. It's more likely there is something wrong with that drive than your windows install, but a fresh format will give you the answer.
