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 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 raw read error rate fail "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 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

low framerates when loading new areas despite having more than enough ram and more than adequate video card. If anything is using the hard drive, like say I'm unzipping a file, other programs won't launch at http://askubuntu.com/questions/20393/how-do-i-interpret-hdd-s-m-a-r-t-results 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" for raw read error rate, and the Health Status of the drive says "Ok" as well. I ran an error scan and it http://www.tomshardware.com/forum/267401-32-st3250318as-high-read-error-rate 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 Current: 100 Worst: 100 Threshold: 36 Data: 0 Seek Error Rate Current: 78 Worst: 60 Threshold: 30 Data: 79436688 Power On Hours Count Current: 91 Worst: 91 Threshold: 0 Data: 8688 Spin Retry Count Current: 100 Worst: 100 Threshold: 97 Data: 0 Power Cycle Count Curren

I recently realized that the disk was noticeable slower than before, so I decided to check the SMART data. Everything seemed to be read error rate 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 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 h
S.M.A.R.T. is the abbreviation for "Self Monitoring And Reporting Technology". It is a standard interfaceprotocol and set of the disk features that allowsdisk to check its status and report it to a host system. S.M.A.R.T. information consists of "attributes", each one describing some particular aspect of drive condition. Some attributes may be designated "life-critical", which implies that the corresponding parameters are more important than other ones. Three values are associated with each S.M.A.R.T. attribute: "Normalized value", commonly referred to as just "value". This is a most universal measurement, on the scale from 0 (bad) to some maximum (good) value. Maximum values are typically 100, 200 or 253. Rule of thumb is: high values are good, low values are bad. "Threshold" - the minimum normalized value limit for the attribute. If the normalized value falls below the threshold, the disk is considered defective and should be replaced under warranty. This situation is called "T.E.C." (Threshold Exceeded Condition). "Raw value" - the value of the attribute as it is tracked by the device, before any normalization takes place. Some raw numbers provide valuable insight when properly interpreted. These cases will be discussed later on. Raw values are typically listed in hexadecimal numbers. Most common S.M.A.R.T. attributes reference Note that not all of the attributes are present on all drives. Some attributes are of similar meaning (just counted differently), so only one of them will normally be monitored by the drive. Some require special sensors (e.g. temperature or G-loads monitoring). The decision about which attributes should be implemented is up to the drive vendor. Along the same lines the interpretation of raw values depends heavily on the manufacturer.
