Clicking Noise Problem
In October 2009, a "clicking" noise problem was identified on external and barracuda drives from Seagate. The symptoms are frequent clicking sounds which interrupt the data reading on the hard drive. These problems have been reported on the Seagate forum and in an article from PC Pro (UK). Some participants in the aforementioned Seagate forum report successfully remedying the problem by replacing the USB cable Seagate provides with a higher-quality one or by re-routing the cable to avoid radio frequency interference from other cables. The click of death has most commonly been seen in models where (ST3500641AS) is stated on the box but on the hard drive itself is (ST3500320AS).
