Looked at your Smart logs - no issues at all there. If the noise is not consistent, then it is not likely the click of death- it may just be normal HD sounds. Check in the system BIOS and see if acoustic management is enabled for the drive. This makes it a tad slower, but is designed to reduce the HD noise. Other than that, take it back to the place of purchase and let them check it. Your SMART values tho indicate the drive is functioning at 100%. Some bad sector errors and read errors are normal on any drive over time. particularly read errors. But drives are designed to handle that transparently to the user, by re-reading ( happens ALL the time)
