Raw Read Error Rate 1
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 menu and ran the long SMART diagnostics from this. However, since the documentation for Disk Utility is very raw read error rate western digital 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?

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). Differen

In Health tab of SSD I found Raw Read Error Rate property. What does this property say about my hard drive? OCZ tool shows only 114 total ECC and RAISE errors. But what does Data column in HD Tune mean? Why the description says that disk had 89.970.873 read errors? It is new disk. I installed it yesterday and it is passing all diagnostic tests in SeaTools, Performance tests in HD Tune Pro and common check in Chkdsk. hard-drive ssd diagnostic smart share|improve this question asked Feb read error rate 12 '11 at 10:43 Ladislav Mrnka 3682719 add a comment| 3 Answers 3 active oldest votes up vote 4 down vote accepted The HD Tune data looks quite suspect. For example, I don't believe that you had a temperature peak of 129 degrees celcius. And as you say, the ECC recovered rate is simply ridiculous. Since this is an OCZ disk, I would go with OCZ tool, and take its findings as the correct ones. If you are worried about 114 ECC and RAISE errors, the best is to get in touch with OCZ Support, and ask if they advise to use the warranty to exchange the disk. Their answer, if positive, will give you the necessary ammunition when dealing with your vendor. share|improve this answer answered Feb 12 '11 at 10:56 harrymc 191k7166408 1 The Current and Worst values for temperature can never be read directly from SMART data. The software has to convert it into a readable value, sometimes this varies by drive too so the software has to be coded for certain drives. I don't know about HD Tune Pro but I know Smartmontools can output the correct temperature for most drives. –Arrowmaster Feb 12 '11 at 16:39 Can you also explain what does Raw Read Error Rate mean? –Ladislav Mrnka Feb 12 '11 at 17:10 It means the drive has bad blocks that prevent the computer from reading its contents normally. A high rate means that the disk is failing, which is why I suggested to contact Support, just in case. &nd

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 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.

If the normalized value is above the threshold, you're fine. Keep your backups up to da
