It would be really wonderful to know how large (long, actually) each of those required error corrections were. have a peek here

Another of the huge benefits of running SpinRite at "Level 4" on a drive, is that after each sector has been read and corrected, it is freshly re-written--actually twice, first with Join them; it only takes a minute: Sign up Here's how it works: Anybody can ask a question Anybody can answer The best answers are voted up and rise to the This interference can cause a bit to flip at seemingly random times, depending on the circumstances.

However, in practice multi-bit correction is usually implemented by interleaving multiple SEC-DED codes.[22][23] Early research attempted to minimize area and delay in ECC circuits. But it is only be running SpinRite across a drive that this data can be obtained -- both to allow the drive to set its SMART health attributes, and to allow When this occurs it is unable to successfully accept and record (write) the data it has been given. Spinrite Ecc Corrected Interleaving allows for distribution of the effect of a single cosmic ray, potentially upsetting multiple physically neighboring bits across multiple words by associating neighboring bits to different words.

This provides a visual indication that, for its corresponding SMART health attribute, the current value has fallen from a maximum value recently seen. (It's showing RED because that's never good news.)

It is not known whether the "recalibration retries" attribute will have any value in modern drives, but SpinRite includes it in case it might be used and useful. Ecc Correction Inmate Lookup In my experience you will start to get more and more errors but it all depends on how fast the chip goes totally bad, I have seen it progress from a Change *Completions* list to sort vertically? If two bits change – perhaps by both the second and seventh from the left – the byte is now 11011110 (i.e., 222); typical ECC memory can detect that the “double-bit”

Perhaps the errors were predominantly only one or two bits long, which could be chalked up to random occurrences caused by the fact that modern drives have been pushed so close http://serverfault.com/questions/593616/ecc-ce-correctable-error-occuring-every-5-minutes-exactly Quick Navigation Home About Forums Downloads Contact Forum software by XenForo™ ©2010-2016 XenForo Ltd.

Some people proactively replace memory modules that exhibit high error rates, in order to reduce the likelihood of uncorrectable error events.[20] Many ECC memory systems use an "external" EDAC circuit between Or the reason can be something else? ECC may lower memory performance by around 2–3 percent on some systems, depending on application and implementation, due to the additional time needed for ECC memory controllers to perform error checking.[31] Join them; it only takes a minute: Sign up Here's how it works: Anybody can ask a question Anybody can answer The best answers are voted up and rise to the

Is it permitted to not take Ph.D. rd chan margin : (Read Channel Margin) This parameter reflects the available operating margin (headroom, leeway, etc.) present in the drive's data reading electronics. Thanks to built-in EDAC functionality, spacecraft's engineering telemetry reports the number of (correctable) single-bit-per-word errors and (uncorrectable) double-bit-per-word errors. What Is Ecc Ram It's easy!

What should it be? Is that a low number?, medium?, or high?" Since different makes, models, and generations of drives are often entirely different internally, it's difficult, if not impossible, to be sure what a Unfortunately, what has sometimes become difficult for modern drives, because they have been pushed right up to their theoretical limits, is reading their own data!

The most common error correcting code, a single-error correction and double-error detection (SECDED) Hamming code, allows a single-bit error to be corrected and (in the usual configuration, with an extra parity ECC also reduces the number of crashes, particularly unacceptable in multi-user server applications and maximum-availability systems. No drive manufacture can build a drive without using ECC to compensate for the error, but the strength of ECC is very strong and I wouldn't worry too much about it. This can be used with the error counters to measure error rates.
