Smart Test Seek Error Rate


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 Get the answer Ask a new question Read More Hard Drives Seagate Storage Related Resources S.M.A.R.T.

Start Backing Up Free The Other SMART Stats We compiled and placed online our list of all the SMART stats I took it to a repair shop where they replaced the inverter board … I deleted a startup file by mistake!! 2 replies I very much appreciate this site. In fact my Internet research tends to confirm a maximum of 120 for 7200.11 models, but the threshold figure is 6. While I'm willing to believe your conclusion about 187, for me it's more of a question of how often 197 goes above 0 and what the self-test if revealing, not just

What Is Seek Error Rate

If it stresses the drive too much could it fail because of that during the rebuild? where the factor of 512*8 is used to convert from sectors to bits. What's especially useful is that "scan" outputs an overview of the latency of the sectors it's scanning as it goes.

  • 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
  • That being said, it's paid for itself and then some.

  • But the servers in a datacenter that I'm familiar with usually remain powered on at all times.
  • Some hide it.
  • The formula also refers to sectors being transferred "ToOrFromHost" which doesn't make sense for a read attribute.
  • 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 =
  • Page 3Eh or Page 62 Decimal.
  • When I received it, I immediately ran SMART tests and looked for any issues, like this, before starting the transfer (especially UPS delivering).
  • That would be normal as it's doing several operations at once and the read/write heads are moving back and forth.

Played a variety of formats with no problem. What Does Seek Error Rate Mean Choosing the Right Stats to Use There are over 70 SMART statistics available, but we use only 5.

pretty much a dying drive. Seek Error Rate Seagate Only other thing I see is the load cycle count is a bit high due to the APM on the drive, but is common for the newer Seagate drives since they I believe the relationship between the raw and normalised values of the SER attribute is given by ... CentOS 7, Zimbra 8.6 and FirewallD yum and fastestmirror plugin...

I would perform a surface scan with MHDD in DOS mode. Hardware_ecc_recovered To determine if a drive is going to fail soon we use SMART statistics as evidence to remove a drive before it fails catastrophically or impedes the operation of the Storage 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 sttv Can you release the full database of all raw data values?

Seek Error Rate Seagate

It drives me nuts when I see blog posts/web articles with only averages and then the author tries to make conclusions based on probably insignificant differences. Phillip Remaker They use consumer grade drives to keep cost down, all SATA. What Is Seek Error Rate I have a Seagate 500Gb 7200.10 (about 3 years old) that has a high seek error rate.I know that the raw data field has a different structure for different vendors and Seek Error Rate Fix The "scan" command has provided me some insight into drive surface issues.

Some are pretty tight together, does it help to just loosen them?I'm rebuild of my server and that puts the project back to the drawing board. navigate here Anyway, have discovered this evening that my laptop has started suddenly shutting down. After it records 1 million seeks the SER is recomputed to reflect the actual SER. shouldn't it be higher than that for a new sata drive. Seek Error Rate Western Digital

So, this is very very small fraction of errors. Seek Error Rate Failed So I decided to buy a 2TB to replace that drive and put the 1TB in a separate lower power pc just for downloading / seeds. Most of our drives have very few power cycles.

The thing that was bothering me about these drives was the UDMA_CRC_Error_Count, though most of that may have come from one cable problem. The following information has not been gleaned from any official source, but is based on my own testing and observation, and on testing by others. Logged unRAID 6.3.0-rc3 Pro on Asus F1A75-V Pro/AMD A8-3870, 32GB (4*8GB DDR3 2100MHz), Corsair CXM750, CyberPower CP1500EPFCLCD Backup UPS, Verbatim Store'N'Go 2GB, 2*AOC-SASLP-MV8, 4*SuperMicro 5in3 cages in Antec 1200 case, Parity: What Is Raw Read Error Rate Of the 4 drives, I have replaced 1 in the last ~50000 hours.

Since the manufacturers don’t tell us what their attribute values could be, this SMART stat is not very useful, especially across multiple drive manufacturers. Not drive related?Looks like disk 10 timed out and refused to reconnect. There's a port of DTrace available for Linux now, and if I'm not mistaken there's also a DTrace work-alike for Linux that might provide some insight. this contact form Confusing, and some values sit on 200 or are not normalized...

After some time, 196 and 197 return back to 0. SMART goes here to get its reporting intervals too.

That’s answered by the next chart: This looks at the full time range of the study, and counts “drive years”. Looks to be a fairly new drive, so might be a data/power cable slightly loose. Maybe someone with more syslog expertise can give you more input on the specific error you are seeing. 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.

That was about 32000 hours ago and concerns the drive that has been running for ~32000 hours.
