Raw Read Error Rate 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 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

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 of which could diagnose only http://superuser.com/questions/853177/can-i-modify-the-smart-value-of-raw-read-error-rate-worst-value-to-be-greater-th 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 components have failed (best case that'd mean soldering new components t
Wiki1 Answer Elizabeth GreeneWritten 71w agoHard drives store digital data in analog format by magnetizing and de-magnetizing tiny microscopic areas of a metal coating on a disk spinning thousands of times per minute. This process is amazingly precise, but https://www.quora.com/What-causes-hard-drives-to-have-high-raw-read-error-rate not perfect. Electrical, Mechanical, Environmental and Chemical issues can cause errors in the data that http://h30434.www3.hp.com/t5/Notebook-Hardware-and-Upgrade-Questions/Raw-Read-Error-Rate-Errors-occurred-while-reading-raw-data/td-p/4029508 is read back from the disk. If the errored data happens to contain your life's work, this is a bad thing. To reduce this problem drive manufacturers design the disks with Error detection and correction techniques. These allow the drive to detect bad data and fix it before it gets passed back to the operating system. A raw read error is triggered read error when the drive detects that it read bad data. Automatically fixing the bad data is a very good thing, but it means you don't always know that a drive is failing until it is too late. Drive manufacturers don't want you to lose data. Nobody wins when you lose data. To help prevent data loss the drive collects error statistics including a count of raw read errors. This technology, called S.M.A.R.T., hopefully gives you a warning to raw read error identify and replace a failing drive before losing data.3.2k Views · View UpvotesView More AnswersRelated QuestionsHard Disk Drives (HDD): What is the meaning of "raw read error rate"?Hard Disk Drives (HDD): What is more predictive of impending hard drive failure: seek error rate or raw read error rate?Hard Disk Drives (HDD): Why is a hard drive's "raw read error rate" important?Hard Disk Drives (HDD): What is the difference between a hard drive's "raw read error rate" and its "soft read error rate"?Hard Disk Drives (HDD): How is a hard drive's "raw read error rate" analytically measured?What are the most common reasons of "write error rate" in hard drives?Hard Disk Drives (HDD): What is more indicative of hard drive failure: "write error rate" or "raw read error rate"?What causes hard drives to have high "spin retry count"?What causes hard drives to have high "g-sense error rate"?What causes the bathtub curve failure rate in hard drives?Hard Disk Drives (HDD): Why is a hard drive's "g-sense error rate" important?Is it possible to rescue data from external hard disk with CHKDSK RAW drive error?What causes hard drives to have high reallocated sectors count?Is it possible to periodically scan for the error rate of a hard drive every once in a while?How high a drop above concrete flooring is equivalent to the common 350G shock rating for hard disk drives?How do hard drives re
