Hi, I own an intel macbook and have noticed over the past month that it has occasionally started to freeze and make a clicking sound. Usually after restarting I can get the computer to function normally, other times it requires two restarts. I downloaded and ran three 3rd party applications to scan the disk and tell me it's status. Both SMART Utility and DiskRadar say "failing" and give me a message saying "196 Reallocated Event count" as well as "197 Current Pending Sector". On the other hand, the macbook's own SMART status says it's fine as does SmartReporter. Can someone explain what "reallocated event count" and "current pending sector" mean? Will I need a new computer? I should mention that this computer is 3 years old now and I had replaced the original hard drive that came with the computer with a larger hard drive from Hitachi about a year and a half ago. All my data has been backed up but I want to know if there is anything I can do to fix the problems or if there is no hope. thanks!
