Raw Read Error Rate Smart
The best answers are voted up and rise to the top How Do I interpret HDD S.M.A.R.T Results? up vote 40 down vote favorite 10 My laptop has recently started to 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 raw read error rate fail 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 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? (Thanks) hard-drive smart share|improve this question asked Jan 6 '11 at 23:46 Marty 78021015 Has the "Hardware ECC recovered" same value as "Read error rate"? 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 wi

Only 1 reallocated sector, just the ECC needs to fix the raw medium errors, which is normal given the data density. Harddrives don't really know what they are storing anymore, only after ECC has been applied is the data reliable enough not to have any bit errors. In other words, its normal that the raw read error count is quite high. All modern disks are vulnerable to this issue. Related resources Internal HDD Raw Read Error Rate - Forum Raw Read Error Rate

I recently realized that the disk was noticeable slower than before, so I decided to check the SMART data. Everything seemed to be OK. A bit more than a year powered on, head flew for 11 months... and all the read errors successfully corrected; no big deals. I decided to note anyway the read error rate, which had a value of 60M (normalized 119, threshold 6, worst 99). Today (3 days after), I checked raw read error again those numbers and the read error rate value is at 215M, which seems to me like a huge increase in a little time. The normalized and worst values haven't changed anyway, so the assesment is still OK in the SMART data. Should I be worried? My data is backed up, but should I be already buying a new HDD for my laptop? hard-drive smart share|improve this question asked Jan 21 '15 at 22:09 Peque 551312 It may be simply a loose connection. Try to disconnect the HDD and install it again. –gronostaj Jan 21 '15 at 22:15 @gronostaj: The HDD is mounted with screws, but anyway I will try that. Thanks! :-) –Peque Jan 21 '15 at 22:29 1 There has to be some type of data connection. 215 million errors is not normal. Be sure you understand how S.M.A.R.T should be read it snot always obvious. –Ramhound Jan 21 '15 at 23:37 The raw value isn't very meaningful by itself, and not very reliable to predict any failures. If the normalized value is above the threshold, you're fine. Keep your backups up to date, that's all. –Pedro Werneck Feb 21 '15 at 15:43 1 215 million errors is perfectly normal and an inherent part of how modern hard drives operate. Most drives will however hide all errors from you if they can correct them - Seagate is the notable exception here. The raw value before erro
"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.
