C2750 Sata Issues

[rkenig]

I have a C2750d4I running freeness 9.3 for the last 6 months. In the last 2 weeks I keep having my 5 drives detach after several hours. I have reseeded the SATA cables and can get the drives working again. I have replaced the cables and it works but then seems to drop out again. I have to wiggle the cables and I eventually get them to see the drives. The drives haven't stayed up. Any ideas
