"What SMART Stats Tell Us About Hard Drives"
"What SMART Stats Tell Us About Hard Drives"
https://www.backblaze.com/blog/what-...rive-failures/ "What if a hard drive could tell you it was going to fail before it actually did? Is that possible? Each day Backblaze records the SMART stats that are reported by the 67,814 hard drives we have spinning in our Sacramento data center. SMART stands for Self-Monitoring, Analysis and Reporting Technology and is a monitoring system included in hard drives that reports on various attributes of the state of a given drive." Smart. Lynn |

"What SMART Stats Tell Us About Hard Drives" https://www.backblaze.com/blog/what-...rive-failures/ http://www.extremetech.com/computing...s-about-to-die Cites BackBlaze data 2 years ago on 40,000 drives. The same SMART attributes mentioned back then to monitor the health of an HDD are the sames ones mentioned in their newer blog. That SMART doesn't dictate reliable prediction of failure is probably due to the leniency allowed to HDD manufacturers on how they report the SMART values or the means they use to mask them. When a non-zero Current Pending Sector Count value doesn't drop to zero is when I get concerned that the drive can no longer mask its newly detected bad sectors to reserved space on the HDD. There is no more reserved space for the remapping so the bad blocks remain in use. The reallocation of data to the reserved space can't happen until the data gets read from the bad block to move it. If the bad block is so bad that repeated read attempts fail to capture the data then the bad block cannot be mapped (by moving the data to reserved space). |

TY Smart. Yes. How long the drives were in operation would have added more insight. The 4GB Toshibas are far older than some of the Seagates.

No air conditioning, but they turn the fans on in hot weather. Perce |
