A high Seek Error Rate most directly suggests which issue?

• A. Potential head issues.
• B. Power supply failure.
• C. CRC errors.
• D. Reallocation.

Answer: (A)

A high Seek Error Rate indicates a problem with the drive’s head positioning system. When the actuator struggles to move the read/write head to the correct track, you see more errors during seek operations. This points to potential issues with the heads, servo mechanism, or actuator circuitry, which can lead to misalignment or failed seeks and is a sign of mechanical trouble inside the drive.

CRC errors are data-transfer problems and don’t necessarily imply the head can’t position correctly. Reallocation happens when unreadable sectors are remapped to spare ones, which is about bad data areas rather than the head’s ability to seek. A power supply failure would cause broader symptoms affecting many aspects of operation, not specifically a surge in seek errors.
