Introduction

When using CrystalDiskInfo to monitor the health of your hard drives, you may come across a warning that reads "Current Pending Sector Count" or "Pending Sector Count." This warning can be alarming, especially if you're not familiar with the terminology. In this article, we'll delve into what the Current Pending Sector Count (PSC) means, how it's calculated, and what it indicates about the health of your hard drive.

What is the Current Pending Sector Count (PSC)?

The Current Pending Sector Count (PSC) is a metric used by CrystalDiskInfo to measure the number of sectors on a hard drive that are pending, meaning they are waiting to be written or read. These sectors are considered "pending" because they are in a state of limbo, neither fully written nor fully read. The PSC is a critical indicator of a hard drive's health, as it can signal potential issues with the drive's mechanical or electronic components.

How is the Current Pending Sector Count (PSC) Calculated?

The PSC is calculated by CrystalDiskInfo by analyzing the hard drive's SMART (Self-Monitoring, Analysis, and Reporting Technology) data. SMART is a built-in feature of modern hard drives that monitors various parameters, including temperature, vibration, and power consumption. The PSC is one of the many SMART attributes that CrystalDiskInfo tracks to provide a comprehensive picture of a hard drive's health.

What Does a High Current Pending Sector Count (PSC) Indicate?

A high PSC can indicate several potential issues with your hard drive:

  • Mechanical failure: A high PSC can be a sign of mechanical failure, such as a faulty head or a malfunctioning actuator. When a sector is pending, it may be due to the head being unable to read or write the sector correctly.
  • Electronic failure: A high PSC can also indicate electronic failure, such as a faulty controller or a malfunctioning buffer. When a sector is pending, it may be due to the controller being unable to process the sector correctly.
  • Bad sectors: A high PSC can also indicate the presence of bad sectors on the hard drive. Bad sectors are areas on the disk that are unable to be read or written due to physical damage or other issues.

How to Interpret the Current Pending Sector Count (PSC) in CrystalDiskInfo

When interpreting the PSC in CrystalDiskInfo, it's essential to consider the following factors:

  • Threshold values: CrystalDiskInfo provides threshold values for the PSC, which indicate when the count is considered high or critical. These threshold values vary depending on the hard drive model and manufacturer.
  • Trend analysis: Analyze the trend of the PSC over time. If the count is increasing, it may indicate a problem with the hard drive.
  • Comparison with other metrics: Compare the PSC with other SMART attributes, such as the Reallocated Sector Count (RSC) and the Uncorrectable Sector Count (USC). A high PSC in conjunction with other warning signs may indicate a more severe issue.

What to Do if You Receive a Warning About the Current Pending Sector Count (PSC)

If you receive a warning about the PSC in CrystalDiskInfo, it's essential to take immediate action* Backup your data: Immediately backup your data to an external drive or cloud storage to prevent data loss.

  • Run a disk check: Run a disk check using the built-in Check Disk (chkdsk) utility in Windows to identify and repair any bad sectors.
  • Replace the hard drive: If the PSC is high and other warning signs are present, it may be time to replace the hard drive with a new one.

Conclusion

The Current Pending Sector Count (PSC) is a critical metric used by CrystalDiskInfo to monitor the health of your hard drives. A high PSC can indicate potential issues with the drive's mechanical or electronic components. By understanding what the PSC means, how it's calculated, and what it indicates, you can take proactive steps to prevent data loss and ensure the longevity of your hard drives.

Introduction

In our previous article, we explored the concept of the Current Pending Sector Count (PSC) in CrystalDiskInfo reports. We discussed what the PSC means, how it's calculated, and what it indicates about the health of your hard drive. In this Q&A article, we'll address some of the most frequently asked questions about the PSC and provide additional insights to help you better understand this critical metric.

Q: What is the difference between the Current Pending Sector Count (PSC) and the Reallocated Sector Count (RSC)?

A: The PSC and RSC are two separate SMART attributes that provide different information about the health of your hard drive. The PSC measures the number of sectors that are pending, meaning they are waiting to be written or read. The RSC, on the other hand, measures the number of sectors that have been reallocated, meaning they have been marked as bad and are no longer accessible. While a high PSC can indicate potential issues with the drive's mechanical or electronic components, a high RSC typically indicates that the drive has already experienced physical damage.

Q: Can a high Current Pending Sector Count (PSC) be caused by a faulty controller or a malfunctioning buffer?

A: Yes, a high PSC can be caused by a faulty controller or a malfunctioning buffer. When a sector is pending, it may be due to the controller being unable to process the sector correctly. This can be caused by a variety of factors, including a faulty controller chip, a malfunctioning buffer, or a software issue.

Q: How can I determine if a high Current Pending Sector Count (PSC) is caused by a mechanical or electronic issue?

A: To determine if a high PSC is caused by a mechanical or electronic issue, you can analyze the trend of the PSC over time. If the count is increasing, it may indicate a mechanical issue, such as a faulty head or a malfunctioning actuator. If the count is stable, it may indicate an electronic issue, such as a faulty controller or a malfunctioning buffer.

Q: Can a high Current Pending Sector Count (PSC) be caused by a software issue?

A: Yes, a high PSC can be caused by a software issue. For example, if a program is writing data to the drive in a way that causes the drive to become overwhelmed, it can lead to a high PSC.
