Help interpreting SMART data

Post by dsmithdewarcom »

This is not NAS or RAID -related. Can someone help me understand the following SMART report from a desktop pc that has had intermittant drive failure (my suspicion is that the issue is with motherboard/power supply -- note the mb only supports SATA 1, hence the 1.5GB/s)

Code: Select all
