This means the sectors were really just held a weak magnetic charge, and were not permanently bad from e.g.

Despite the clear indication of potential failure, all sectors were restored to full working order after being written over. It also just so happens that none of the data I had stored on the drive were on these bad sectors. Since I waited 8 months to run this test and used the drive sparingly, it's unclear whether the sectors were always bad or if they developed over time. I had backups just in case, so I wasn't worried and was mainly doing this for science.At the end, SMART output showed 2310 bad sectors existed on the drive.

I ran a read test on Windows using HD Tune Pro since that's where my drive was plugged in at the time, and the results (shown in as screenshots attached to this review) show the drive did in fact contain some bad sectors.I ran a non-destructive write test using badblocks on Linux which, for each sector, will first read the sector and store it in memory, then write a random pattern, then read this pattern back and make sure it matches the pattern that was written, and finally restore the original contents of the sector.
This prompted me to fully check my drive's health so that I could at least be reassured that it is in full working order for the time being. For more details, please continue reading.Having recently re-browsed the Amazon reviews for this product, I saw some people complaining that their drive had failed after x months having ordered it around the same time as me. I received this drive 8 months ago and it is still working in an acceptable manner by my standards.
