I have a HP Pavilion g6 2136tx Laptop which was functioning correctly until one day Windows 7 Ultimate x64 couldn't boot up. 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 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.

  1. What are the options that I have except replacing the disk?
  2. 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?

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).

  1. 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.

  2. 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, changing it won't make it work any better. You could in theory upload a new firmware to the drive to report a lower value (again, in theory, this is not an easy approach). Some drives also have serial (as in "serial port") interfaces, though normally soldering is required, and you might be able to manipulate the values through that interface.

Seagate purchased Samsung's hard drive business, so you can check if its still under warranty with the Seagate Warranty Validation page.

  • I just want to install Windows 7 onto the drive. I have another 2TB drive for back up. That is why I want to edit the values so as to fool Windows to get installed on the drive – John Paul Dec 17 '14 at 13:03

    @JohnPaul, as derobert already said, changing the value wouldn't make the drive work any better. I also doubt that Windows refuses to install because of the SMART error. It's more probable that it just fails to install because the drive is broken. – n.st Dec 17 '14 at 13:09
  • @n.st: I just wanna make the drive bootable. And I just transferred some iso files of size 13 to 25 GBs and am able to read and write smoothly. Also tried copying and deleting small files like pictures and they worked well too. The HDD was working really smooth earlier and it still is. The only nitpick is the SMART error. Windows setup specifically says that the drive has a SMART error, and hence installation wont continue.I understood that changing the value wont affect the disk performance, I just want to boot Windows 7 from the disk. – John Paul Dec 17 '14 at 19:35
  • @JohnPaul sounds like you need to ask a question about how to bypass that check in the Windows installer. – derobert Dec 17 '14 at 19:46
  • @derobert: Instead of asking a whole new question, wouldn't it be better if you just tell me how to do it - bypassing SMART check in Windows installer? – John Paul Dec 18 '14 at 5:47

Unfortunately, drives fail, there is no "End-of-life-date" for any type of HDD, regardless of manufacture or size. You could have had that drive for 10 days or 10 years, they just fail for all sorts of reasons. You can't just edit the drives RAW Read Rate, it is a hardware issue, not a software issue. You need to backup your data and get a new HDD. You could try to get it replaced by Samsung if it's still in it's warranty period:


Best of luck to you John Paul!

  1. Unfortunately there are no other options than replacing the drive. HDDs are complex and precise pieces of equipment. Actually there is less than 1 Nanometer between the platters and the head inside the HDD. 1 Nanometer equals 0.000000001 Meters, you cannot just open it and fix it. Nor can you fix a hardware problem using software tools. I'm sorry for your drive but there is just nothing that could help in this case.

  2. It is possible to modify the value but that won't fix the drive. This value is just a indicator for the problem it's not the problem itself. Raw Read Error Rate indicates the Frequency of errors appearance while reading RAW data from a disk. Another thing with SMART values is that the higher the Current Value the better. SMART values don't start from 0 and count to 255 ( for example), but instead start from 255 and count down to 0. When the Current value is near and below the Threshold you get notified that the drive is failing. So the value of 1 is the worst value you can get. Even if you modify it and it shows 52 this won't change a thing. The HDD still won't be able to read a thing.

  • Minor nitpick: many failures are actually of the control electronics, which wouldn't require opening the drive to repair, as the board is mounted to the bottom of the drive. But of course, repairing that isn't practical either. – derobert Dec 16 '14 at 19:02
  • @Techpumpkin_WD: How can I achieve what you said in 2nd point about modifying the value? At least by changing the value, I can fool Windows to get installed on this drive. I already have another 2TB drive, so backup is not an issue. – John Paul Dec 17 '14 at 13:01
  • @JohnPaul I'm sorry but even if you change the value you won't be able to install Windows. This HDD is dead. – Techpumpkin_WD Dec 17 '14 at 15:13
  • @Techpumpkin_WD: Please tell me whether any software can be used to change it? I want to try it before trashing it. – John Paul Dec 17 '14 at 19:37
