My drive is failing because of Attribute 196- "Reallocated Event Count "- and this is the only reason it is reporting as failing. Is this accurate?
There has been mixed reports about the accuracy of this attribute- especially by itself. It is supposed to note when a bad sector was removed from active service. However, it is also supposed be matched with an increase in the "Reallocated Sector Count"- but some drives do not do this.
So while it may be an indication of a failing drive, it also may be an indication that the drive is okay but giving a false positive. This is why there is an option to ignore this attribute- and if the drive is failing other attributes will indicate that instead.
