Strange loss with transition to new OS using AW8-Max

I am not sure if this is a function of Vista, or the way I have my
hard drives set up. or my BIOS settings.or my Abit motherboard...but I
am having a strange problem. I had a windows XP computer with 5 hard
drives in it, that I wanted to convert over to Vista, I have a brand
new SATA hard drive that I installed my Vista OS on, so I am only
brining over 4 of the hard drives to this new computer. I bought a
new motherboard that had only one ide controller, rather than the 3 my
other computer had. My new motherboard (Abit A8W-MAX) has 6 SATA
ports on it, so what I did was I bought SATA to IDE controllers and
set up all of the hard drives except for one using the SATA->IDE
converter. When I turn on my computer, all of the hard drives are
recognized, vista boots up fine and I can use it, howver there is one
strange thing that happened in the transition. Out of the 4 hard
drives that I brought over, 2 of them are still labeled as the same
and have all of the files....the other two have the label of NEW
VOLUME, and are completely blank?!?! Has anyone else had or heard of
this issue? Any help?
