1.I have heard about ATA-100 and ATA-66 , What are they ? and What is the difference ?
2.According to Cable for HardDisk , I see that it has two type , one for 40 lines cable, another is 80 lines.
What is the difference ? When should I use either 40 or 80 lines cable ? Can I use 40 instead 80 , and in turn 80 instead 40 ??? CAN I ??
