Aging HDDs: CrystalDiskInfo and Other Tools for Assessing Drive Health


“As an expert, could you evaluate the health of HDDs with approximately 70,000 hours of operation, equivalent to 8 years of uptime? Are there any concerning signs I should look for in CrystalDiskInfo reports, or is there a risk of imminent failure? Additionally, could you recommend alternative software for error checking on these aging drives?”


When it comes to hard disk drives (HDDs), longevity is a testament to their resilience but also a sign of wear that could lead to failure. With approximately 70,000 hours—or 8 years—of uptime, your HDDs are undoubtedly in the latter stages of their lifecycle. As an expert, I would advise close monitoring and preparation for potential replacement.

CrystalDiskInfo is a valuable tool for gauging the health of your HDDs. Here are some critical parameters to monitor:

  • Reallocated Sectors Count:

    A high number indicates that the drive has found bad sectors and reallocated data—a warning sign of potential failure.

  • Current Pending Sector Count:

    These are sectors that the drive has identified as problematic but has not yet reallocated.

  • Uncorrectable Sector Count:

    Sectors that could not be fixed and data was lost. A non-zero value here is concerning.

  • Power-On Hours:

    Confirms the age of your drives. In your case, this should read close to 70,000 hours.

  • Drive Temperature:

    Consistently high temperatures can accelerate wear.

  • Risk of Imminent Failure:

    While these drives may continue to operate without issue, the risk of failure increases with age and usage. It’s prudent to back up data regularly and consider replacing drives that show signs of significant wear.

    Alternative Software for Error Checking:

    Apart from CrystalDiskInfo, you can use the following tools to check for errors and assess drive health:

  • GSmartControl:

    An open-source tool that offers a user-friendly interface for smartctl, part of the S.M.A.R.T. monitoring system.

  • HDDScan:

    A freeware utility that checks for bad sectors, displays S.M.A.R.T. attributes, and can run various tests on HDDs.

  • SeaTools:

    Offered by Seagate, this diagnostic tool works with drives from any manufacturer and provides a variety of tests to determine the health of your HDDs.

  • In conclusion, while your HDDs have served well beyond the average lifespan, it’s essential to remain vigilant for signs of failure. Regular backups and considering upgrades to newer storage technologies will ensure data integrity and system reliability. Remember, no HDD lasts forever, and proactive measures are key to avoiding data loss.
