I have a Micron Millennia Max, PIII 500MHZ, with a SE440BX2 motherboard, 32-bit Ultra ATA33 hard drive controller. In 1999 the system came with a 13 GB western digital hard drive, small by todays standards. I am experiencing problems with movie making due to my hard drive capacity. Can I upgrade to a higher capacity hard drive with this motherboard? And, if so, what is the largest I can go?
