Your motherboard has just USB1.1. Unless you have upgraded it to USB2.0 you will find an external hard drive very slow. Better to get an internal, as you wanted with a 7200 spin speed and a large cache.
1. If I have a Slave for all my Personal stuff like my writing, all my Family Pictures etc will I have to install my Operating System on to the slave as well.
2. Yes External Hard Drive for backing up I have, but its only 120gig. I have not used it fore some time now.
3. Somebody told me that because my computer is seven yours old, my Motherboard may not be able to take more than a 40 gig Internal Hard Drive. If I did put in anything more than that I'd have to Partition, say 60gig new drive so that my computer will recognise the new drive
4. No I don't have USB2. I put a USB 2 card in some time ago & it was not regognised, so I returned it QVC where I bought it from.
1. No - once you`ve installed it format it and start using it as you suggest. 2. Stick with your 120Gb External Drive as an additional storage or backup facility. 3. I think it`s the operating system that determines the ability to see drives but we can cross that bridge if you come to it. 4. With your mobo you won`t know any difference between USB1 & 2 - I don`t!
With an external drive there is no restriction on the size...it is a much easier option, believe me. Unless you are gaming, swopping a terabyte of info every hour or video-editing, you will find little difference in USB1 or 2 so the fact that you only have USB1 is irrelevant.
