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
Raw Read Error Rate Fail
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 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 bet

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 1 problem: Raw Read Error Rate: Threshold Value: 51, Current Value: 1, Worst Value: 1 All the softwares predicted imminent drive read error rate 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 to the control board on the bottom of the drive), but that's not really practical. You ask if you can modify the SMART values. They're not intended to be edited, and doing so wouldn't be useful. The value is just an indicator, ch

Manufacture date shows as January 2012 (yes that's as new as new can get), so must be one of the new batches from the post-flood Thailand. Anyway, I downloaded a copy of Active Hard Disk Monitor tool to check the S.M.A.R.T. parameters and I find the parameter Raw Read Error Rate is very low. Should I be worried? Will this rectify over time? This hdd is just 7 hours old; what gives?

This is just the magic that goes on behind the scenes all the time on a high density drive, and when a user looks at this smart data it scares the hell out of them. –Moab Feb 24 '12 at 17:01 add a comment| 2 Answers 2 active oldest votes up vote 2 down vote It seems it may be a count of the actual sectors read, the errors are in the upper 16bits of the 48bit word, please see http://forums.seagate.com/stx/board/crawl_message?board.id=ata_drives&message.id=25651 On my Seagate drives I have high decimal numbers, but when converted to hex I in fact have 0 errors in a whole lot of sectors read. share|improve this answer answered Jun 28 '12 at 18:52 Andrew 212 add a comment| up vote 1 down vote GSmartControl has a comment about this in the tooltip for the raw
