become a bit unreliable, and for some reason I started to suspect that my HDD was starting to fail. After a bit of hunting on the internet, I found Ubuntu's Disk Utility in the System menu and ran the long SMART diagnostics from this. However, since the documentation for Disk Utility is very poor (palimpsest?), I'm not sure how to interpret the results: For example, the Read Error Rate is over 50 million (!), yet the Assessment is rated "Good". So what is raw read error rate would someone mind explaining to me how to interpret the results of these tests (especially the Normalized, Worst, Threshold and Value numbers)? And maybe tell me what they think of the results I got for my HDD?

My disk has 676 power cycles, was powered on 285 days, and has 193M errors. Compared to mine, your disk has way too much error, but I'm just speculating here. Anyways I just got worried myself o.O –danizmax Jan 7 '11 at 8:47 Yip - both numbers are the same! –Marty Jan 7 '11 at 16:32 add a comment| 3 Answers 3 active oldest votes up vote 32 down vote accepted You have a good description of how SMART works on the wikipedia. But a quick intro: Value: This is the raw value that the controller reports. Usually it's an easy to understand value (like power on hours or temperature), but sometimes it isn't (like the read error rate). Different manufacturers can use different structures and meanings for this data. Normalized: This is the above value normalized so a higher value is always better. So a 114 in read/error rates is better than 113. Again, how your hard drive converts raw data to normalized value is vendor specific. Worst: The worst normalized value that

Games will drop to extremely low framerates when loading new areas despite having more than enough ram and more than adequate video card. If anything is read error using the hard drive, like say I'm unzipping a file, other programs won't launch at all until the first app using the hard drive is done. So, I opened HD Tune Pro, which I've had for quite a while but never use, and I noticed that the Raw Read Error Rate is *extremely* high; 125154961 to be exact. However, the status column says "Ok" read error rate for raw read error rate, and the Health Status of the drive says "Ok" as well. I ran an error scan and it showed no bad sectors, so I thought that number must be normal, so I checked my second drive, which is six years old, and it shows zero for Raw Read Error Rate. There are also other high error rates in the list of stats for the newer drive, and oddly two negative stats for lifetime reads and writes. It doesn't make any strange noises, as people often say they hear when a drive is starting to fail. My power settings are set to spin the drive down after 30 minutes. The drive is connected via SATA. (My second drive is connected via PATA and slaved to an PATA CD/DVD drive if that could have anything to do with it) This is the complete list of stats: HD Tune Pro: ST3250318AS Health Raw Read Error Rate Current: 117 Worst: 99 Threshold: 6 Data: 125498017 Spin Up Time Current: 97 Worst: 97 Threshold: 0 Data: 0 Start/Stop Count Current: 100 Worst: 100 Threshold: 20 Data: 161 Reallocated Sector Count Curre
"Self-Monitoring, Analysis, and Reporting Technology". First developed in the 1992 by leading hard drive manufacturer, S.M.A.R.T. becomes a quasi standard to monitoring and tracking sensitive values from your drive to prevent hard drives from fail. The plan was, if a hard drive says 'I will die soon', the motherboard tell us, so we can backup and change quick the drive. Unfortunately this doesn't works very often. Attributes, Values, Thresholds and S.M.A.R.T. examples Attributes describes the measured value of hard drive controller operations. The values of an attribute are: current, worst, threshold and raw. Values are normalized to a vendor specific scale. Scales could be ranged up to 100, 200 or 253. Often higher values are better than lower values. The threshold marks the value at which the hard drive could fail. The worst value is the baddest value seen for this drive at this attribute. The raw value is a vendor coded count that give, after decoding, the normal values like current, worst and threshold. S.M.A.R.T. Interpretation First some important knowledge about threshold values. If threshold is 0 the attribute has only information character. If threshold is 253 the attribute is only for testing reason. A typical attribute set could be: Attribute name: "Read Error Rate" Current: 253 Worst: 253 Threshold: 63 Raw: 0 All right , this is a nice set. Nothing happens at this attribute. Only if this attribute reach the threshold value 63, we should have to change the hard drive. Let's look on a attribute with a warning status: Attribute name: "Read Error Rate" Current: 113 Worst: 85 Threshold: 63 Raw: 1234567 The hard drive have sector read errors in the past, but work fine for now and (perhaps) work fine in the near feature. However, I would now start to make more often backups and begin to plan a hard drive change. It is difficult to make correct interpretations in general, because different vendors normalize values in different way. We can recommend to ask in vendors forum for interpretations if you are unsure. Attribute Hit List We will give a list of important attributes. We highly recommend to look at these SMART attributes first. Read Error Rate [Stores data related to the rate of hardware read errors that occurred when reading data from a disk surface] Rea
