The “device error count” refers to the running total of errors recorded by your drive. It includes such errors as: ID Not Found (for valid Logical Block Addresses), write fault errors, servo errors, and uncorrectable errors. It excludes errors caused by faulty commands. These errors can indicate potential issues with the drive’s health or performance.
Types of Device Error Count
A low number of device errors is usually not a major concern as they can be caused due to temporary glitches. A moderate number of errors could be an early warning of developing issues, such as communication problems between the drive and the host system, or small, correctable hardware failures. It’s a good idea to monitor the situation and potentially back up important data just in case.
A high or rapidly increasing error count is a sign that the drive may be failing. This could indicate issues such as bad sectors, read/write failures, or physical degradation of the drive. If the error count is high, you should immediately back up your data and consider replacing the drive.
Impact of High Device Error Count
A high device error count can significantly impact the health and longevity of a drive in several ways:
- Decreased Reliability: A high error count often indicates underlying hardware issues that can make the drive less reliable and more prone to data corruption or failure.
- Increased Risk of Data Loss: When errors accumulate, the drive’s ability to store and retrieve data reliably is compromised, increasing the chances of data corruption or loss.
- Slower Performance: As a drive encounters more errors, it may take longer to read from or write to the disk. The system may attempt to retry the operation several times or use error correction techniques, which can degrade performance and slow down overall system operations.
- Frequent Crashes or Freezes: A high error count can lead to instability in the system and shorten the drive’s lifespan. You may experience crashes, freezes, or even an inability to boot the system, depending on the severity of the errors.
