SMART attributes statistically closely related to HDD or SSD failures.
For example, some Intel SSDs could report some strange results when its firmware performs garbage collection routines.ġ) Some subset of HDD / SSD health indicators is related not only with HDD / SSD itself but also with hardware environment (computer, ports, cables, power supply, drive and ambient temperature and (sometimes even) electrical noise).Ģ) DriveDx evaluates drive health status based on the next criteria: SSD results could be affected by internal firmware activities related to garbage collection and self-recovery routines. High temperatures could trigger thermal throttling and affect the performance of SSDs. some other vendor-specific health indicators.Temperature, vibration level or electrical noise conditions could affect the following health indicators (SMART attributes): Quality of data cables affects health indicator #199 “(UDMA) CRC Error Count”. Fluctuation of “Spin-Up Time” indicator usually means that drive have not enough power supply or has not optimal temperature conditions or both. However, most modern computers have the ability to stop a drive while the machine is already running as a means of energy conservation or noise reduction. Spin-up generally occurs at the very beginning of the computer boot process. Health indicator “Spin-Up Time” reports average time (in milliseconds or seconds) of spindle spin-up (from 0 rpm to fully operational). In the case of HDDs: #3 “Spin-Up Time” is mostly affected by power supply health indicator. SSDs and especially HDDs could be sensitive to power supply level, and high performance 7200+ RPM HDDs could be very sensitive to power supply level. I thought that was a great gesture on their part.Some subset of HDD / SSD health indicators is related not only with HDD / SSD itself but also with hardware environment (computer, ports, cables, power supply, drive and ambient temperature and (sometimes even) electrical noise). They were able to retrieve almost all of the files before it finally died and then put them on the new drive they installed - no charge. I called the LaCie office in Toronto and they told me to pack it up well and send it along. I didn't think it was totally dead, since I could still get some files from it. In all the years I've been at this I've only had one HDD crap out. I have three Boot-Clones and three backups of my main work drive, so I think I'm probably covered. " If you only have one backup, you don't have a backup". I read a quote many years ago and have adhered to it ever since. And your assessment of the financial aspect of buying a new drive is dead on. Fault-detection is interesting, but not helpful enough to justify its cost and aggravation".Īs I read some information on the DriveDx site it occurred to me that indeed, wouldn't it be rather late once a drive issue is detected? Sort of like closing the barn door after the horse has left. "Even if that problem-diagnosis provided perfect detection of failure, it is still too late to do anything about it, and the solution is still to restore from your Backup.
