Now I don't want to use my old ATA133 HDD as the booting drive as it is used as at present. If after installing Win7 onto the new drive, can I just plug the old one back in and access all the personal files on it? as if I just plugged in a USB data stick for example.
My aim would be to just delete what I don't need from the old one and kepe it for photo storage etc.
I don't want to go through the hassle of backing up everything to then put it back.
