Ok now this might sound confusing but I will try and explain what I did as best I can. My original configuration was a 160 GB hard drive and a 200 GB slave HDD. I was in the process of upgrading video cards but had to use an old one while I waited for it to arrive. During this time I experienced problems loading my OS (Windows XP Pro W/SP2). I tried to tweak my way around the problem, but inadvertently started a reinstallation and screwed something up now the only thing I get is "NTLDR is missing". My main objective is to access the drive to back-up my files, roughly 140 GB, I've already tried reloading windows but it say's I don't have enough free space - erase disc. I ended up taking out both HDD's and put in a new 80 GB and loaded Windows XP Pro W/SP2 with large HDD support. That is working just fine. I then put my original C: drive in as the slave drive. Jumpers are all set correctly. The slave drive does show up under "My Computer", however it says it's only 10 MB with 3 MB free. I am assuming that the 10 mb is a partition of my original set up or formatting of the drive. If anyone has any ideas at all PLEASE HELP!!! Thanks in advance, this board is great.
