I have been noticing performance issues recently, and in an attempt to diagnose the issue I ran a smartctl. I'll paste the full output below here but a few things stuck out at me, I'm just wanting to ensure I'm reading this report correctly. By what I'm seeing it appears my drive is past the threshold on raw read error's and spin up time. It also appears to have spiked at an extremely high temperature at some point (likely leading to the errors). These stats seem to indicate the drive is in "pre fail" condition and is likely to die at any moment. If someone would be willing to just look it over and confirm my suspicions, or call me an idiot and school me on how to properly read the report that would be great
The Raw_Read_Error_Rate attribute is sick (86) , but it is still above the failure threshold (62). The Reallocated_Sector_Ct (181) is worrisome, too. I would backup regularly and not entrust any important data to this drive.
BTW, your drive appears to have a very aggressive autoparking setting.
This means that your drive parks its heads every 37 seconds, on average. You might like to reconfigure its APM settings using a utility such as hdparm. However, since APM settings are volatile (ie they don't survive a power cycle), then you may need to have hdparm run automatically at every boot.
