I'm trying to upgrade with a new 128GB SSD drive from Runcore and I cannot get the drive to be recognized. While booting from the Snow Leopard DVD, I go to Disk Utility, and no physical hard drive is recognized. The old drive is about to go so I can't boot off of that. Does anybody have any troubleshooting advice? The cable seems very durable so I presume it's either the SSD connection or the SSD itself? Is it possible for the cable to be damaged invisibly or is those chances pretty slim?
