Haikk..problem solved. I can actually access my files on my old hdd.

My hdd disk jumper setting was auto-detect (by cables) at first. There was a plug an play error. I couldn't even boot up Windows. But when i changed it to Master and Slave, i was able to boot Windows. But i had a few errors while the OS was detecting the old hdd. My guess is that using the auto-detect, the driver had to be loaded first, so when there were errors, the OS cannot finish loading. I'm worried that the errors were not related to the file system. Might be a slight incompatability between the hdds.

Spent my whole day messing with the hdds. Installed stuff i needed except MS Office. My cd is not working. Haisss.
