Overview
QNAP NAS systems support both S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) and IronWolf Health Management (IHM) to monitor the health of installed hard drives. Occasionally, these two systems may report different health statuses for the same drive, which can lead to confusion.
Explanation
Understanding the Differences
S.M.A.R.T. is an industry-standard technology built into most hard drives. It reports drive health based on various measurable attributes, such as reallocated sectors, read errors, and spin retries. A warning from S.M.A.R.T. typically means that the drive has already shown some degree of physical degradation, such as bad blocks or early-stage mechanical issues.
IHM is a Seagate-specific system that supplements S.M.A.R.T. data with environmental and workload analysis. It uses predictive models to identify patterns that may lead to future failure but may not flag all raw S.M.A.R.T. attribute warnings.
In some cases, S.M.A.R.T. may issue a warning due to minor errors or aging indicators, while IHM still considers the drive “healthy” because the errors have not yet reached a critical threshold in its predictive model.
Recommendation
If your S.M.A.R.T. status shows “Warning” or “Abnormal”, even when IHM says the drive is “Healthy”, we strongly recommend the following actions:
Back up your data immediately.
Monitor the S.M.A.R.T. attributes such as:
Run a Complete S.M.A.R.T. Test from Storage & Snapshots > Disks > Health Info to check for ongoing degradation.
Replace the drive if your data is important or if the S.M.A.R.T. warnings persist or increase over time.
Even minor S.M.A.R.T. warnings can be early signs of a failing drive, and it is safer to replace the drive proactively rather than risk sudden failure later.
Note
When S.M.A.R.T. shows a warning, it means that physical degradation has begun—even if the drive continues functioning. Continuing to use the drive increases the risk of data loss.

概述
QNAP NAS系统支持S.M.A.R.T.（自我监测、分析和报告技术）和IronWolf 健康管理 (IHM)来监控已安装硬盘的健康状况。有时，这两个系统可能会对同一硬盘报告不同的健康状态，这可能导致混淆。
解释
理解差异
S.M.A.R.T.是一种行业标准技术，内置于大多数硬盘中。它根据各种可测量属性报告硬盘健康状况，例如重新分配的扇区、读取错误和旋转重试。S.M.A.R.T.发出的警告通常意味着硬盘已经出现了一定程度的物理退化，例如坏块或早期机械问题。
IHM是一个Seagate特有的系统，它通过环境和工作负载分析补充S.M.A.R.T.数据。它使用预测模型识别可能导致未来故障的模式，但可能不会标记所有原始S.M.A.R.T.属性警告。
在某些情况下，S.M.A.R.T.可能会发出警告由于轻微错误或老化指标，而IHM仍然认为硬盘是“健康的”因为这些错误尚未达到其预测模型中的关键阈值。
建议
如果您的S.M.A.R.T.状态显示“警告”或“异常”, 即使IHM表示硬盘是“健康的”, 我们强烈建议采取以下行动：
立即备份您的数据。
监控S.M.A.R.T.属性，例如：
运行完整的S.M.A.R.T.测试从存储与快照总管 > 磁盘 > 健康信息以检查持续的退化情况。
如果您的数据很重要或S.M.A.R.T.警告持续或随着时间增加，请更换硬盘。
即使是轻微的S.M.A.R.T.警告也可能是硬盘故障的早期迹象，主动更换硬盘比冒突然故障的风险更安全。
注意
当S.M.A.R.T.显示警告时，这意味着物理退化已经开始——即使硬盘继续工作。继续使用硬盘会增加数据丢失的风险。
