Answer to: 2011 Mac mini Dual Hard Drive Kit - bad cable?I think you may have gotten a bad cable. Contact iFixit support staff to obtain an RMA number and get a replacement fast. Don't worry, we're on the same boat. I ripped apart my Mac mini more over than 5 times, only to narrow down the problem; faulty SATA cable. Now, I'm waiting for them to get back to me regarding the replacement part.
