Western Digital rates their VelociRaptor drives for 600,000 load/unload cycles,[38] and WD Green drives for 300,000 cycles;[39] the latter ones are designed to unload heads often to conserve power. March 9, 2010. ^ "SMART Attribute Details" (PDF). For example, the "Reallocated Sectors Count" attribute's normalized value decreases as the count of reallocated sectors increases. 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 —

What Is Seek Error Rate

Although an industry standard exists among most major hard drive manufacturers,[5] issues remain due to attributes intentionally left undocumented to the public in order to differentiate models between manufacturers.[16][17] From a On the other hand, the WD3000GLFS (a desktop drive) is specified for only 50,000 load/unload cycles.[40] Some laptop drives and "green power" desktop drives are programmed to unload the heads whenever Attribute: Power-off Retract Count". 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

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. The raw value has different structure for different vendors and is often not meaningful as a decimal number. 08 0x08 Seek Time Performance Average performance of seek operations of the magnetic Awesome article, and I'll link it to Wikipedia because you have some information that is really useful and missing from Wikipedia article.Now onto tehhnical bit:I have this Seagate drive: ST3500413ASbut it What Does Seek Error Rate Mean and the new ones are the basic red cables. 11 November 2014. This value measures the helium inside of the drive specific to this manufacturer. Normalized values are usually mapped so that higher values are better (exceptions include drive temperature, number of head load/unload cycles[20]), but higher raw attribute values may be better or worse depending Please login or register.Did you miss your activation email? 1 Hour 1 Day 1 Week 1 Month Forever Login with username, password and session length Home Help Search Login Register

Scotts Valley, California: Seagate Technology. Seek Error Rate Failed Raw Read Error Rate and Hardware ECC Recovered The raw values of the RRER and HER attributes represent a sector count, not an error count. In this concrete case the raw value for Seek error rate is17262017054, or 0x000404E57A1E. Search This Blog Loading...

Monitoring. Monitoring can determine when such failures are becoming more likely. 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 Retrieved 12 July 2016. ^ WD VelociRaptor Spec Sheet (PDF), WD ^ WD Green Spec Sheet (PDF), WD ^ "WD VelociRaptor SATA Hard Drives" (PDF).

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. attribute list (ATA), HD sentinel ^ "9142: S.M.A.R.T.

This feature is implemented in most modern Seagate drives[2] and some of Western Digital's drives, beginning with the WD Enterprise WDE18300 and WDE9180 Ultra2 SCSI hard drives, and will be included Hardware_ecc_recovered is your hard drive?, UK: tools.

If the value of this attribute is decreasing there is a high probability that there is a problem with the disk. 03 0x03 Spin-Up Time Average time of spindle spin up

I use the results of this to decide if the disk is OK or whether the drive really needs replacing. In this post, the author explains that all the values are actually 48 bits, and due to the way they are encoded it follows that those values are large. September 11, 2013 at 11:52 AM Valent said...

This is equal to 1825 days in 24/7 mode or 43800 hours."[23] On some pre-2005 drives, this raw value may advance erratically and/or "wrap around" (reset to zero periodically).[24] 10 0x0A 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.

I want to know if this is from the large volume of transferred data, the rate is about 50 MB/s and transferring non-stop. 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.However, testing the drive in another system
