Smart Data Seek Error Rate


For each stat we display the failure rate charts based on the raw and normalized values we recorded. Error Recovery Usage Rate = -log10 {(Number of sectors in which controller invoked specified error recovery scheme)/[(Number of sectors transferred) * (512 bytes/sector) * (8 bits/byte)]} This lends support for my Try benchmarking the drive. Can you tell how good this HDD is from the SMART data I'm posting? http://unordic.com/error-rate/smart-seek-error-rate.html

I handle this by having a spare drive that has been previously put through a thorough pre-clear to check it out. However, Seagate calculates and applies these attribute values in a counterintuitive way. We have a large storage array with a number of different drive models and would love to start monitoring this. As such, it would have been more interesting (for me) to relate the rate of increase of 187 compared to drive failures. you can try this out

What Is Seek Error Rate

But I generally look for it going a lot slower than usual, bios not reading it some random time, anything that doesn't seem right. AMD (17 items) Intel Seagate disk SMART values...

  • If you run n drives for t years with an annual failure rate of r, the number of failures is expected to be n * r * t.
  • fzabkarJul 23, 2014, 9:21 PM The drive may have "weak" sectors which don't show up in SMART.

  • Sam McLeod Hi Guys, I'm re-writing a script I found to report on critical SMART data from all local block devices - https://github.com/sammcj/smart_diskinfo It appears that smartmontools 6.4 doesn't seem to
  • Ask !

Check your cable routing, don't stack a bunch of SATA cables together tightly as one would typically want to do to keep things tidy. This first chart shows the failure rates by number of errors. Could the parity be build invalid if this drive fails in the process?I'm scared of using these "problem drives", but I'm not that fond of getting a new drive EVERY time What Does Seek Error Rate Mean Currently the Power-on Time parameter (0000h) is the only parameter in this Log Page that is visible to OEM/customers." Most Enterprise drives use this Page.

I was just looking at smartctl output from one of my disks, and it had a large number for Seek error rate attribute (note that I edited the output for readability): Seek Error Rate Seagate 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 just finished doing a retest of these drives by preclearing them without any indications of trouble. You may ask whether there is a correlation of power cycle count with failures because power cycle count correlates with age, and age correlates with failures.

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 Since the drives are running in RAID1, I remove the drive from the array and ‘fix' the drive by writing to the LBA that's failing. What Is Seek Error Rate Cloud backup. Seek Error Rate Fix 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

Seagate disk SMART values... this contact form I believe the relationship between the raw and normalised values of the SER attribute is given by ... 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 As others pointed out, raw values of parameters like "reallocated sector count" or entries in the drive's error log are more likely to indicate a higher probability of failure. Seek Error Rate Western Digital

I tried Crystal Disk Info and the values are hard to figure out and my hard drive doesn't show the same attributes as mentioned in the blog. Get the answer Ask a new question Read More Hard Drives Seagate Storage Related Resources S.M.A.R.T. That would be normal as it's doing several operations at once and the read/write heads are moving back and forth. have a peek here By itself, it's going to be a performance concern, but probably not that big a concern as far as data integrity goes.As far as data integrity, pay more attention to the

Despite this, the numbers in most cases are perfectly OK. Hardware_ecc_recovered While a value above 0 is not good, the inconsistency of the reported values above 0 is wildly inconsistent as seen in the charts above using normalized values. Backblaze counts a drive as failed when it is removed from a Storage Pod and replaced because it has 1) totally stopped working, or 2) because it has shown evidence of

Keep an eye on the value.

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. solved my smart tv UA55H6400AR. Does this look like the HDD will fail soon?

Personally, I consider a drive containing error log entries as "failing" and urge for a replacement as soon as they occur. I'm not sure if a windows reboot would count as a power cycle or not. fzabkarJan 5, 2011, 8:42 AM The normalised value of Seagate's Seek Error Rate is logarithmic. Check This Out That’s answered by the next chart: This looks at the full time range of the study, and counts “drive years”.

The latency seems to be generated when the drives built-in error correction mechanisms kick in. Nevertheless, if we ignore the threshold anomaly, then for each block of 10^12 bits read ... Do you generally just test cables and try to rebuild drive and if it fails to rebuild then replace? If at the end of that there are no signs of any problems you have reasonable confidence that this point the drive is showing no problems.

If it stresses the drive too much could it fail because of that during the rebuild?

Bltserv Another really good piece of Information about a drive is "Power On Time" Its a Factory Log Page that can be looked at with software. If you have a controller, RAM, or PSU issue in the server it can effect preclear results as well. SMART stats are inconsistent from hard drive to hard drive. 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.
