    Exclamation Help please - Sudden Seek Error Rate Change

    Hi, this morning I was doing normal dusting out of my computer with compressed air. Afterwards I ran a SMART test on my drives, which I do often, and noticed an alarming performance/fitness drop. Yesterday it was reporting overall fitness of 93% and performance of 100%. Here is the data as of today:

    Your hard disk is a WDC WD2500JS-22NCB1 with firmware 10.02E02.
    The average temperature for this hard disk is 39C (MIN=26C MAX=54C) and yours is 40C.

    Raw Read Error Rate 200 0 Very good
    Spin Up Time 197 5116 Normal
    Start/Stop Count 100 377 Very good
    Reallocated Sector Count 200 0 Very good
    Seek Error Rate 100 0 Watch
    Warning: Seek Error Rate is below the average limits (150-200).
    Power On Hours Count 93 5362 Normal
    Spin Retry Count 100 0 Very good
    Calibration Retry Count 100 0 Very good
    Power Cycle Count 100 373 Very good
    Unknown attribute 190 60 40 Good
    Reallocated Event Count 200 0 Very good
    Current Pending Sector 200 0 Very good
    Offline Uncorrectable Sector Count 200 0 Very good
    Ultra DMA CRC Error Rate 200 1 Very good
    Write Error Rate 200 0 Very good


    NOTE: not all warnings are reflected on fitness and performance overall values as relevancy is based upon the settings from the hard disk manufacturer who is the best entity deputed to define such relationships.


    The overall fitness for this drive is 45%.
    The overall performance for this drive is 45%.

    I'm assuming this drop is due to the seek error rate warning, which was not there yesterday. Is this something I need to be concerned with? I know how inaccurate these readings can be, however readings on this drive have always been consistent until today. Not quite sure how dusting it out could've caused this.

    SMART tests can cry wolf sometimes. I'd keep an eye on it, consider backing up your critical data, line up a warranty check and replacement.

    Also can download and run WD's own diagnotic utility for a more detailed 2nd opinion.
