Just to add something to think about. I can't recall how SMART says this but a drive that failed on me several years ago said the drive was dying and it was going to die soon, I think 24 hours was mentioned. I unmounted that drive and removed power until I had a replacement drive. Once the replacement drive came in, I hooked the drive back up and copied the data over to the new drive. I seem to recall I had a couple pics and a couple text files that were corrupted. I might also add, I started running some tests on the drive and it died a few hours later. I could hear it spin but it wouldn't even mount anymore. If you see something similar to that, I suggest you take action since it could be accurate. It was in my case. If the data has no value or you have known good backups, then it may not matter so much. Dale :-) :-)
