I use XP Pro etc, and have just bought a new Hard Drive, my intention is to install this one alongside the old one,and use the new one as the main drive and the old one for storage etc, but I don't want to copy the whole contents over as I thought a clean install might be best.
I have created a folder on the old drive and put loads of files into it, my thoughts are;- Initially I would install the new drive and disconnect the old one whilst I put Windows on and other programs I use, if I do not complete all this in one go then I can always disconnect it and reconnect the old drive to run on.
When all is complete I hope to use the old drive for storage etc and hopefully the folder I have created will be accessable. I hope to be able to copy those over and then do a format of the old drive.
Seems ok to me but get the jumpers and position on cable set correctly. If new drive set to master and connected to end of cable and old drive set to slave and on middle connector then i cannot see a problem with both drives being bootable! If Cable select supported (need to have compatible cable)and both on Cable select then so long as the new drive is on the end connector this should be ok as well.
