Raw Read Error Rate 1

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 would raw read error rate ssd 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 normalized value that your driver had
SMART reports, therefore it should not be considered authoritative. Accuracy however is highly desired, so please feel free to correct it as needed, or suggest corrections or question

Tried System Restore and Windows Startup Repair tool, both of which failed. Finally removed the HDD and connected it as external to another laptop. Tried many HDD Scan SW all read error rate of which could diagnose only 1 problem: Raw Read Error Rate: Threshold Value: 51, Current Value: 1, Worst Value: 1 All the softwares predicted imminent drive failure and that all data should be backed up. Hard Drive Model: Samsung Spinpoint ST500LM012 500GB manufactured by Seagate, 5400RPM The Date of manufacture is May 2012 and the drive has never failed ever. I removed all partitions and also did a deep format of the entire disk, but the error is still there. What are the options that I have except replacing the disk? Can I modify the SMART value of Raw Read Error Rate Worst Value to be greater than 1 as I saw many manufacturers allow it be greater than 1? Is it editable and if yes, how to do it? hard-drive smart share|improve this question edited Dec 17 '14 at 12:50 asked Dec 16 '14 at 10:19 John Paul 1116 add a comment| 3 Answers 3 active oldest votes up vote 2 down vote accepted The SMART counters measure the physical/electrical performance of the disk. They're supposed to alert you when the disk is about to experience a failure (or, in your case, already has). You ask if there anything you can do except replace the disk. No, it's a hardware failure. You could replace whatever
Sep 8, 2014 Messages: 3 Thanks Received: 0 Trophy Points: 1 Hi! Short version: Raw_Read_Error_Rate has creeped up to 1 on a new WD Red after running SMART tests and badblocks. RMA the drive? Long version: System: Supermicro X10SLH-F-O Xeon E3-1231 v3 4 x 8GB Samsung ECC Memory (from Supermicro's compatibility list) 6 x 4TB Western Digital Reds (WD40EFRX) Seasonic 460W Fanless (SS-460FL2 Active PFC F3) Antec 300 Illusion FreeNAS 9.2.1.7 Built the system, original PSU was DOA, ran memtest for 48 hours, memory checked out. Then ran SMART tests. My testing went something like this: For each disk: $ smartctl -t short /dev/adaX $ smartctl -t conveyance /dev/adaX $ smartctl -t long /dev/adaX Then: $ sysctl kern.geom.debugflags=0x10 And for each disk: $ badblocks -ws /dev/adaX $ smartctl -t long /dev/adaX $ smartctl -A /dev/adaX First time I did this everything went fine. Disks were staying around 30 deg C, they weren't agressively spinning down, no errors reported. SMART values all looked sane. (The runtime for the long tests and badblocks seemed to vary between the drives, but I'm guessing this is due to slightly different rotation speeds?) I rebooted and repeated the SMART and badblocks tests again. Tests passed (again), but I noticed that Raw_Read_Error_Rate is now 1 on one of the disks. This disk is the "oldest" of the bunch: I bought the drives over a period of ~2 months and was playing with FreeNAS before I had all the drives. Should I be worried? I'm running the long tests again on that drive, and am thinking of running badblocks again. The system has been on for several weeks straight at this point, but besides testing it has been unused (been really busy... :/). Thoughts? (I tried searching the forums for Raw_Read_Error_Rate but just found a lot of people posting their smartctl output... sorry if this has been asked many times before...)
