Default Hardware ECC Recovered (HDD, not SSD)

My hard drive seems to have this value increasing pretty quick. I'm writing new files right now, and whenever I refresh the SMART status (every minute let's say), the value has increased by a few thousand. At the moment it's 7324736.

What does this mean? I can't find much information on this smart value.

This is for an HDD, not an SSD!

I quite sure you don't have to worry about that smart counter. Its sometimes really high for some manufacturers (millions/billion for a seagate I had) and doesn't signify a potential problem.

Even if it's constantly growing as mentioned?

This is on an SSD, right? Not an issue.

No, it's on an HDD.

Bump? I think you all assumed that it was a SSD, which it is not.

Is the drive Seagate? If so itís apparently normal to constantly increase.

maybe it's the amount of data written to the disk?

The value may be any ECC recovery. SNR gets lower as density increases, so ECC is constantly being used, as some portion of each read or write may have some defects. The kind of recovery you'd want to worry about is recovery that needed read retries, which you may or may not be able to glean from SMART values.

It's probably like the load cycle count for WD 3.5" Green and 2.5" Blue drives: ever-increasing values may just be a sign of continued normal operation.

When it has to mark sectors as bad, and/or re-allocate, that's when you should worry.

Default What ECC means

ECC = Error Correcting Code memory is a data storage code for testing the accuracy of data passing through it.

The raw value of Hardware ECC Recovered as a decimal number represents a sector count, not an error count. This value rolls over to 0 once the count reaches about 250 million.

The ECC value also rolls back to 0 after low level disk format.

As long as the HDD is not reflecting uncorrectable errors, its operation might be normal.
