Solved Two hard drives Tags: Hard Drives Western Digital NAS / RAID Storage Last response: May 21, 2010 9:50 PM in Storage Share tsekatsu May 21, 2010 8:10:50 AM I was wondering. If I have two hard drives Do I have to use them in Raid or can I add the one in with the other, and get it to work immediately? also Can they be different sizes? because I was curious if I could put in my old 500Gb WD Hard drive in with my 1Tb WD hard drive and add space. Both have Windows Vista 64, would that be a problem as well? thanks More about : hard drives | E-mail me updates | Report abuse Register or log in to remove Best solution uh_no May 21, 2010 8:14:28 AM you can use both at the same time its just if both have windows on them, you have to make sure you go into the bios and set which drive you want it to boot from make sure your boot order is set as you wish and you should be great | Report abuse tsekatsu May 21, 2010 9:50:11 PM Best answer selected by tsekatsu. | Report abuse Ask the community Publish Tom's Hardware>Forum>Storage>Two hard drives> Related ressources: ForumRunning two hard drives ForumDual Boot XP Prof and XP Prof on TWO Individual Hard Drives ForumWhy does transfering files between two external hard drives go so slowly?
