Just because the data is good, doesn't mean the interpretations is. –Evan Plaice Jun 15 '10 at 23:16 2 Yup, that is what I have done. The formula also refers to sectors being transferred "ToOrFromHost" which doesn't make sense for a read attribute. For what it is worth, I also checked the SMART info in linux, and it mimics the findings of crystaldiskinfo. #1 Elixer, Sep 14, 2009 Russwinters Senior member Joined: Jul http://wx2me.com/error-rate/seek-error-rate-seagate.php

For example, their Raw Read Error Rate is defined as follows: Normalized Equation: 10log10[BitsRead / (ReadErrors + 1)] SectorsRead = Number of sectors read SectorsToBits = 512 * 8 I just finished doing a retest of these drives by preclearing them without any indications of trouble.

Is the ritual of killing a animal as offering to maa KALI correct? The anxiety arises because we intuitively expect that the normalised values should reflect a "health" score, with 100 being the ideal value. The formula is essentially the same as the aforementioned one. visit I've found for example that most Seagate drives will report that they have many millions of read errors while western digital 99% of the time shows 0 for read errors.
First 16bits is 0x0000, last 32bits are 0x001C453D. Hardware_ecc_recovered I found it very useful. –James T Jun 16 '10 at 19:41 1 smartmontools FAQ says: The raw SMART attributes (temperature, power-on lifetime, and so on) are stored in vendor-specific Thus ECC corrected might be "raw read failed but fixed by ECC + raw read succeeded but was wrong and got fixed by ECC". I know that everyone should backup their data.
tl;dr Summary: Raw SMART values are almost meaningless, as different manufacturers use them in different ways and have different thresholds etc. Seagate's Seek Error Rate, Raw Read Error Rate, and Hardware ECC Recovered SMART attributes Seagate's Seek Error Rate, Raw Read Error Rate, and Hardware ECC Recovered SMART attributes create a lot What Is Seek Error Rate In fact the document mentions (but does not discuss) 5 different error recovery schemes: HARD = multiple retries invoked and failed FIRM = multiple retries invoked SOFT = 5 retries invoked Seek Error Rate Western Digital The millions of seek errors that Seagate produces are still a mystery to me.
max normalised RRER = -10 log (1 / 10^12) = 120 Similarly, if we let the number of errors equal 250 million (ie every sector is errored), then we have ... http://wx2me.com/error-rate/seagate-seek-error-rate.php Member Posts: 360 Re: Seagate with huge Seek Error Rate, RMA? « Reply #6 on: April 02, 2014, 07:17:03 AM » Yes, that is basically what I have done.But I really Which is why I said it is weird, that the drive isn't doing and reading / writing, yes, it is spinning, but no access to it besides polling it for the Similarly, we would expect that the raw values should reflect an error count, in which case a value of 0 would be most desirable. What Does Seek Error Rate Mean
I'm almost certain that the normalised values are also logarithmic, but I'm not sure how they are calculated. Controlling which congestion control algorithm is used in Linux Installing Zimbra 7.2.7 on CentOS 7 and upgrading to 8.6 BIND and network unreachable messages... HD Tune: ST3250623A Health ID Current Worst ThresholdData Status (01) Raw Read Error Rate 45 38 6 77882492 Ok (03) Spin Up Time 99 98 0 0 Ok (04) Start/Stop Count http://wx2me.com/error-rate/seagate-3tb-seek-error-rate.php We find, for example, that after their first scan error, drives are 39 times more likely to fail within 60 days than drives with no such errors.
This is because the raw values are typically very high, and the normalised values (Current / Worst / Threshold) are usually quite low. What Is Raw Read Error Rate You can think of it as I'm suppose to be at track 20000 but I'm actually at 19997, so I need to apply more current to move faster, or vice versa. Or the air flow can be effected.
In addition to correcting raw read errors, ECC also corrects reads that the hardware thought were OK, but the returned bits were slightly wrong. Calculating TCP RTO... Based on the abovementioned Error Recovery Usage Rate formula, I now postulate that the normalised value of the Raw Read Error Rate attribute could be calculated as follows: normalised RRER = Seagate High Seek Error Rate Secondly, SMART thresholds are not standardised.
When this target is reached, the values drop to 60 and 60, assuming there have been no errors. Seagate's Seek Error Rate attribute consists of two parts -- a 16-bit count of seek errors in the uppermost 4 nibbles, and a 32-bit count of seeks in the lowermost 8 You could also use another system as there is no requirement that the pre-clear run on the system where the drive is to be used. More about the author Why would it be uncorrectable?
It takes just 2 minutes to sign up (and it's free!). Is Seagate producing millions of errors while Western digital is producing none? Having these counters go up is honest and fine. However, it also produces an inconsistent threshold value, which is why I have always felt uncomfortable with it.
