9124: S.M.A.R.T. Attribute: High Fly Writes

Applies to:

Operating Systems:

Attribute ID: 189 (0xBD)

Hard drives, supporting this attribute

Seagate, Western Digital

Description

High Fly Writes S.M.A.R.T. parameter indicates the count of these errors detected over the lifetime of the drive. HDD producers implement a Fly Height Monitor that attempts to provide additional protections for write operations by detecting when a recording head is flying outside its normal operating range. If an unsafe fly height condition is encountered, the write process is stopped, and the information is rewritten or reallocated to a safe region of the hard drive.

Recommendations

This parameter is considered informational by the most hardware vendors. Although degradation of this parameter can be an indicator of drive aging and/or potential electromechanical problems, it does not directly indicate imminent drive failure. Regular backup is recommended. Pay closer attention to other parameters and overall drive health.
