this is the first time me being on this forum so bear with me a bit

I was wondering if there is any way to reset a smart false positive
the reason I say it is a false is because the drive says it has "reallocated sector count 0 sectors failing"
never had this kind of thing happen before

any idea's on what is causing this?

im including a screenshot just for kicks i was going to put this drive in a raid array but the array would keep rejecting this drive because of the smart failing

Why would you want to do that?

The smart failure is telling you that there is something wrong with the drive.

The smart isn't the actual problem, there is an underlying issue which will only manifest itself again, probably at the most inopportune moment!

Don't make yourself a "time bomb"!

@james.85.jr,


Unless you know exactly why that SMART attribute is reporting that way (hint: it is highly unlikely that you can know that!) then as pcimage says, any attempt to reset the SMART status (which can be done, but only with specialised software) could be creating a time-bomb for your data.


I suspect your analysis is incorrect, perhaps because unfortunately, that GUI is not displaying all of the data needed to perform a good-quality analysis. Also you left the green "highlight" line on SMART attribute #0 so some of the (currently missing) information about what the disk is reporting for attribute #5, is not being displayed by the GUI.

In short, IMHO get better details of the SMART data from the drive, before making any conclusions. To begin with, I suggest running "smartctl -x" from the smartmontools package (or if that command has problems on your system, start with the more mature (but slightly less useful on larger drives) "smartctl -a") and capture that output into a file. If you provide that output file (in full) from smartctl, then readers here can review the details and may be able to provide more insight.

Do you need the data on this drive? If so, do you already have a backup of that data elsewhere?

I ran smartctl but couldn't find the output file, so i just copied and pasted it all in gedit to save it but it wont let me upload it said extension not allowed i will see if i can copy and past it into the forum

hope all this helps

Thanks for the data. A little info seems to be missing (drive reports that 2 errors have been reported to the host, but none are listed at the end), however the main point is clear:

This data shows a consistent message from both the normalised and raw values of SMART attribute #5, that there is a "threshold exceeded" condition i.e. the drive is telling you that it has a problem. I see no indication of this being a "false positive", now that we have this data.

I can guess why the GUI was showing you a value of "0", but that's a GUI problem. As with many other situations where interpretation of SMART data is done, it is difficult to write software with the necessary flexibility and "knowledge" to correctly interpret all the various ways in which the raw data can be encoded (because recent versions of the ATA spec do not require that raw data to be provided by the drive in any specific way).

Based on that SMART data, personally I would not trust that drive, and it should be eligible for an RMA if it is within its warranty period.

thanks for the info I didn't know that guess I need to buy another hard drive.
To bad this drive is out of warranty iv'e already passed the 6 month return policy
