Seek Errors (low). The phyDrvHSeekErrs and the phyDrvSeekErrs together shows the total number of times that the physical disk drive detected a seek error during the reference hours (phyDrvRefHours). The actual number of seek errors equals the phyDrvHSeekErrs times 2^32 plus the phyDrvWriteSeekErrs. Over time, a disk drive usually produces these errors. If you notice a rapid increase in the value shown for Seek Errors, this physical drive may be failing. The value increases every time the physical drive produces another error. Only an unusually rapid increase in these errors indicates a problem. If you suspect that a problem exists, run diagnostics. If the value cannot be determined, 4,294,967,295 is returned.
