Hi guys, I need some help. I ordered a Seagate HDD. I went to install it, and the cable connects are not compatible. My Dell Dimension 4550 has standard EIDE cables. This new HDD is a SATA drive. The data cable and the power cable are much smaller. So, do I need a different HDD, or do I need some adapter cables. Or, a SATA controller to plug into a PCI slot? This HDD is to be a second HDD, so I can't disable the current controller. Please let me know what I need to do, ASAP. Thanks!
