More specifically, raw value of theSeek error rate attribute should be converted to hexadecimal and then upper 16 bits are number of errors, while lower 32 bits are total number of have a peek at these guys
We do read, analyze and work to improve our content, products and services based off the feedback we receive. Logged unRAID 5.0 Final Pro (Kingston Data Traveller II+ 512MB) / Asus P5Q-E / Intel Q9550 2.82Ghz / 2x OCZ Flex EX 2GB DDR2 PC2-9600 1200MHz / 2x Supermicro AOC-SASLP-MV8 / CentOS 7, Zimbra 8.6 and FirewallD Installing FreeIPA on minimal CentOS installation.. In fact my Internet research tends to confirm a maximum of 120 for 7200.11 models, but the threshold figure is 6.
The Fiercest Hard Drive You’ve Ever Met. What does "Game of the Year" actually mean? Recover We can Recover your Files, Just in Case.
The SMART values that might be read out by third-party SMART software are not based on how the values may be used within the Seagate hard drives. Anyway, I downloaded a copy of Active Hard Disk Monitor tool to check the S.M.A.R.T. Using this disk I go through the process of rebuilding the failed drive onto this spare as its replacement. What Does Seek Error Rate Mean Here's a portion of the output for 1 of the 4 disks.
Should I be worried? Seek Error Rate Fix For the meaning of Seek error rate attribute, and many others, I recommend Wikipedia's page about SMART. I also run short and long self test weekly. http://www.tomshardware.com/answers/id-2229201/high-seek-error-rate-smart.html Do you generally just test cables and try to rebuild drive and if it fails to rebuild then replace?
Ideally you should get a clean preclear cycle in the exact circumstances that the drive will be used in the server. Hardware_ecc_recovered Here are the smarts from my drives so you can compare (note the newer version of unRAID has an updated version of the smart tool that gives some better attribute names The following table correlates the normalised SER against the actual error rate: 90 — <= 1 error per 1000 million seeks 80 — <= 1 error per 100 million 70 — Basically, zero seek errors over 1852733 total seeks.
Simple template. this contact form SkyHawk Surveillance: Smart, Safe, Secure: SkyHawk Surveillance Hard Drives. What Is Seek Error Rate Versatile. Seek Error Rate Seagate That is actually better than you would have for new drives - a significant proportion of those fail when put through their irst stress test via pre-clear.QuoteI think this is a
There are no way to preclear and there are so many possible drives to fail. More about the author When this target is reached, the values drop to 60 and 60, assuming there have been no errors. We're running a number of virtualized servers on it, some that have not been well behaved, and for a significant time the server's io capacity was exceeded leading to bad iowait. If it stresses the drive too much could it fail because of that during the rebuild? Seek Error Rate Western Digital
Therefore it may contain errors. Some of the most common are: Raw Read Error Rate Raw_Read_Error_Rate Reallocated Sector Count Reallocated_Sector_Count Reallocation Count Reallocation_Count Seek Error Rate Seek_Error_Rate Spin Retry Count Spin_Retry_Count Hardware ECC Recovered Hardware_ECC_Recovered Current However, it also produces an inconsistent threshold value, which is why I have always felt uncomfortable with it. http://wx2me.com/error-rate/seek-error-rate-smart.php USB cable and strange behavior with disk in enclos...
In order to see these data, we will need a SMART utility that reports all 48 bits, preferably in hexadecimal. Seagate Smart Values Should non-native speakers get extra time to compose exam answers? Number of sectors requiring retries = 10^ [(120 - normalised RRER) / 10] The following table correlates the normalised RRER against the actual error rate: 120 — <=1 errored sector in
Attribute: Seek Error Rate Applies to: Acronis Drive Monitor Operating Systems: Windows Attribute ID: 7 (0x07) Hard drives, supporting this attribute Samsung, Seagate, IBM (Hitachi), Fujitsu, Maxtor, Western Digital Description Seek However, the high Raw_Read_Error_Rate and Seek_Error_Rate is being pointed to as indications that the drives are dying. What are those HDIO errors? What Is Raw Read Error Rate In case of a failure in the mechanical positioning system, a servo damage or a thermal widening of the hard disk, seek errors arise.
With the backing of personal computer manufacturers, the disk drive industry adopted an analysis system in the 1990's called Self Monitoring Analysis and Reporting Technology, or SMART. The idea then and today Are illegal immigrants more likely to commit crimes? What this means is that there were 4 seek errors (meaning the head wasn't positioned correctly after being moved to some track) but there were82147870 seeks in total. http://wx2me.com/error-rate/seek-error-rate-seagate.php Abstract definition of convex set What is way to eat rice with hands in front of westerners such that it doesn't appear to be yucky?
min normalised RRER = -10 log (1 / 4096) = 36 Therefore, if my hypothesis is correct, we would expect that the threshold value of the RRER attribute would be 36, I actually have a caddy I can plug in externally via eSATA or USB on demand to do this. I'm almost certain that the normalised values are also logarithmic, but I'm not sure how they are calculated.
