SMART-compliant physical disks have attributes for which data (values)
can be monitored to identify changes in values and determine whether
the values are within threshold limits. Many mechanical failures and
some electrical failures display some degradation in performance before
failure
There are numerous factors that relate to predictable physical disk
failures, such as a bearing failure, a broken read/write head, and
changes in spin-up rate. In addition, there are factors related to
read/write surface failure, such as seek error rate and excessive bad
sectors.
Note:
See
for Serial Attached ATA (SATA)
interface specifications.
