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).
Practical Hints on Choosing
Between FAT and NTFS
Enough theory! To learn more about the differences between file systems, read the article titled “Choosing the Right File System: FAT and NTFS”. When exactly do I use FAT, and when should I pick NTFS? Naturally, NTFS should be used within the scope of desktop and laptop computers.
