SMART Parameters and Early Signs
of a Failing Hard Disk
S.M.A.R.T. (or simply SMART) is a monitoring system built into most modern hard drives. S.M.A.R.T. stands for Self-Monitoring, Analysis and Reporting Technology. The technology helps detect various reliability problems at an early stage, giving warning signs well in advance before the hard drive fails. By reading (and interpreting) the indicators, the user can prevent data loss by replacing the disk before the crash occurs. But what S.M.A.R.T. flags should we look at? There are dozens available! This article talks about tools to use and parameters to check for to prevent accidental data loss due to hard drive failure.
Predicting SSD Failures:
Specific S.M.A.R.T. Values
SSD drives don’t have some parameters that are specific to magnetic hard drives. Instead, they have other variables representing overall health of the disk. S.M.A.R.T. tools calculate SSD health by analyzing the following variables: Reallocated Sectors Count, Current Pending Sectors Count, Uncorrectable Sector Count, as well as Percentage of the Rated Lifetime Used (or SSD Life Left, whichever is available).
of NAS Storage Systems
Information above applies to logical errors in external storage systems in a fully working state. But what if some component of your external storage system fails? Or what if your NAS storage is simply worn out? Problems with NAS storage are easy to overlook.
