What do SMART error logs show?

• A. Temperature anomalies only.
• B. UDMA CRC error counts only.
• C. Recent read/write/verify failures and LBAs affected.
• D. Self-test status only.

Answer: (C)

SMART error logs capture the specific error events the drive has encountered. They show recent failures in read, write, or verify operations, together with the logical block addresses (LBAs) that were affected. This combination lets you see exactly where on the disk problems occurred and how the drive was trying to access data when the fault happened, which is the key signal of a failing or failing area. Temperature anomalies and UDMA CRC error counts are separate indicators or attributes within SMART, not the error log’s primary focus. Self-test status is reported in a different diagnostic area. So the error log’s main value is tying actual error events to the exact locations on the disk, illuminating where it’s failing and informing recovery or replacement decisions.
