drive failures, and use the hard drives’ built-in SMART metrics to help. The dirty industry secret? SMART stats are inconsistent from hard drive to hard drive. With nearly 40,000 hard drives and over 100,000,000 GB of data stored

for customers, we have a lot of hard-won experience. See which 5 of the SMART stats are good predictors of drive failure below. And see the data we have started to analyze from all of the SMART stats to see which other ones predict failure. S.M.A.R.T. Every disk drive includes Self-Monitoring, Analysis, and Reporting Technology (SMART https://en.wikipedia.org/wiki/S.M.A.R.T.), which reports internal information about the drive. Initially, we collected a handful of stats each day, but at the beginning smart 187 of 2014 we overhauled our disk drive monitoring to capture a daily snapshot of all of the SMART data for each of the 40,000 hard drives we manage. We used Smartmontools to capture the SMART data. But, before we dig into the data, we first need to define what counts as a failure. What is a Failure? Backblaze counts a drive as failed when it is removed from a Storage Pod and replaced because it has 1) totally stopped working, or 2) because it has shown evidence of failing soon. A drive is considered to have stopped working when the drive appears physically dead (e.g. won’t power up), doesn’t respond to console commands or the RAID system tells us that the drive can’t be read or written. To determine if a drive is going to fail soon we use SMART statistics as evidence to remove a drive before it fails catastrophically or impedes the operation of the Storage Pod volume. From experience, we have found the following 5 SMART metrics indicate impending disk drive failure: SMART 5 - Reallocated_Sector_Count. SMART 187 - Reported_Uncorrectable_Errors. SMART 188 - Command_Timeout. SMART 197 - Current_Pending_Sector_Count. SMART 198 - Offline_Uncorrectable. We chose these 5 stats based on our experience and input from others in the industry because they are consistent across manufacturers and they are good predictors of failure.

Attribute: Read Error Rate Applies to: Acronis Drive Monitor Operating Systems: Windows Attribute ID: 1 (0x01) Hard drives, supporting this attribute Samsung, Seagate, IBM (Hitachi), Fujitsu, Maxtor, Western Digital Description Read Error Rate S.M.A.R.T. parameter indicates the rate of hardware read errors that occurred when reading data from a disk surface. Any value differing from zero means there is a problem with the disk surface, read/write heads (including crack on a head, broken head, head contamination, head resonance, bad connection to electronics module, handling damage). The higher parameter’s value is, the more the hard disk failure is possible. Recommendations This is a critical parameter. Degradation of this parameter may indicate imminent drive failure. Urgent data backup and hardware replacement is recommended. More information See also: S.M.A.R.T. Monitoring. Tags:S.M.A.R.T. Was this article helpful? Yes No This is great!Do you have any comments?
