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.
