Hi, Please advice me, I try to install 2nd hard drive in my HP Windows Vista machine. I took 500GB 2nd hard Drive from my old XP Machine and hookup in Vista machine first it didn't find any hard drive then I use disk management utlity and I can see hard drive but it ask me to run Fdisk before I can use. Now I dont want to loose data and is there any way I can use XP hard drive in Vista Computer? My XP computer is NTFS. Thank you.
