I have a bought a 320 gb western digital cavier blue sata harddrive because my old HDD's (Hitachi Deskstar 160gb) space ran low. Firstly I connected the WD HDD and removed Old HDD. Then I installed new windows xp and also installed Norton Ghost 14.0. Then I connected my old HDD to my PC and used the option 'copy my hard drive' in norton ghost to transfer my old windows xp installation (Full Drive). Norton asked me to restart and proceed by symantec recovery disk. I did this and automatically my new HDD got my old C drive. I booted from my new HDD and saw that my old windows is perfectly running. But then I saw that my old HDD is not shown in my computer and computer management but shown in BIOS. My DVD Drive was shown in My Computer fine. But next day my DVD Drive was also absent from My Computer but present in BIOS. Now help me what to do to get my old HDD and DVD drive back in My Computer. Windows is not detecting both these drives but BIOS does.Help!
