i have no space on my external HDD to put all info from old Internal HDD on, So i cant format the HDD.
can i dissconect old internal HDD with vista on it & then Install New Internal HDD Put PC on, Then install vista via a DVD After Vista Has installed,What would happen if i connect the old HDD with the new HDD both with vista installed on it would i be able to access the data on the old HDD or would i have to format it
