From: Bob on 5 Jan 2006 10:54 I recently installed a SMART monitoring program called Hard Drive Inspector (http://www.altrixsoft.com/en/hddinsp/) and for the past few days it has been telling me about an iminent failure of a Maxtor 160GB ATA disk installed in my PC. The only SMART attribute I can see that is low is the Offline Seek Performance...it's value is 146 (or 73%). HD Inspector includes a graph showing you history values of SMART attributes and during the past few days since the alert has been popping up, the value has stayed at 146 so it does not seem to be getting worse. The lower threshold is much lower than 146. My questions/concerns are: 1) What exactly is Offline Seek Performance? 2) Is this something I need to be overly concerned about given the fact that I am still well above the threshold for this attribute? TIA! Bob

The warning should be taken very seriously. It might be some other attribute that is the problem, not the offline seek performance. Can you post the complete set of smart attributes here? Arno

I'd check the actual SMART values using Everest from http://www.majorgeeks.com/download.php?det=4181 or if that doesnt show the smart data, the smartctl from the knoppix bootable CD. Offline just means tests the drive does by itself, as opposed to what its told to do by a diagnostic. Seek performance is how quickly the drive can move from track to track. If the seek performance is getting worse, that can indeed be an indication that the drive is failing, with the drive not being able to read the new track data properly as quickly as it used to and that may well indicate a problem. Certainly those Maxtors dont look good in the storagereview reliability stats, so I would certainly backup what you'll slash your wrists if you lose even if you have to run out and buy a DVD or CD burner to do that.

Frankly I do not see a problem here. The single reallocated sector is no reason for concern. The spin-up time might be an issue, maybe a PSU with too low 12V line. D1 also seems unproblematic, but could be related to a too low or weak 12V line from the PSU as well (seeks failing because the power gives way a little).
