That's probably not good. Can you direct connect one drive to the controllers and/or bypass the backplane? Same problems! One other important thing is that if your BIOS (and most server BIOS's will do this) detects multiple bit failures it may disable that DIMM slot.

So it would retract its heads back to track zero (a known location) to "recalibrate" their position. How to cope with too slow Wi-Fi at hotel? Speed and Velocity in German How can I have low-level 5e necromancer NPCs controlling many, many undead in this converted adventure? Spinrite Ecc Corrected However, unbuffered (not-registered) ECC memory is available,[29] and some non-server motherboards support ECC functionality of such modules when used with a CPU that supports ECC.[30] Registered memory does not work reliably

As soon as I start reading from drives, counter goes crazy. Normally you wouldn’t expect memory errors, either correctable or uncorrectable, to occur very often. But it's easy enough to demonstrate conclusively. http://www.dslreports.com/forum/r13468823-Hard-Drive-Questions-Spinrite The incidence of correctable errors increases with age, but the incidence of uncorrectable errors decreases with age The increasing incidence of correctable errors sets in after about 10–18 months.

The page discusses how to get started and is also a good location for EDAC resources (bugs, FAQs, mailing list, etc.).Rather than focus on getting EDAC working, I want to focus Ecc Correction Inmate Lookup A DIMM that has a correctable error is 13–228 times more likely to see another in the same month. I'll look into contacting the author. –Chris Tarazi Feb 27 '11 at 20:58 add a comment| 2 Answers 2 active oldest votes up vote 2 down vote accepted It looks like They are saying that this is a normal value for hard drives and that Seagate drives report raw error values, not filtered or rate, like other manufacturers...

Corrected Ecc Error Solaris sb_edac 12898 0 edac_core 46773 3 sb_edac ...
EDAC was loaded as a module, so I examined the directory /sys/devices/system/edac :login2$ ls -s /sys/devices/system/edac/ total 0 0 mc
Because I can only see Ecc Error Correction Code Memory Errors are strongly correlated There is a strong correlation among correctable errors within the same DIMM.

Up to the point where this picture was taken, SpinRite had encountered a one million sector region requiring only 0.83% of its sectors to be corrected (8,323 sectors out of one Ecc Error Correction Code Example

This interference can cause a bit to flip at seemingly random times, depending on the circumstances. Browse other questions tagged hard-drive spinrite . Still it does not explain why error count is 0. size_mb : An attribute file that contains the size (MB) of memory that this memory controller manages.

For example a byte (8 bits)with a value of 156 (10011100)that is read from a file on disk suddenly acquires a value of 220 if the second bit from the left Hamming Distance Error Correction This problem can be mitigated by using DRAM modules that include extra memory bits and memory controllers that exploit these bits. Consequently, I think monitoring and capturing the correctable error information is very important.Linux and Memory ErrorsWhen I worked for Linux Networx years ago, they were helping with a project that was

So data no longer needs to be perfectly stored. levak Member Joined: Sep 22, 2013 Messages: 49 Likes Received: 9 Today a got a new batch of hard drives, this time a Seagate ST4000NM0023. The exciting and worthwhile result is the topic of items 6 & 7 which follow: The primary data SpinRite extracts from the drive's raw data blobs is the count of the What Is Ecc Ram p. 2. ^ Nathan N.

Not the answer you're looking for? But if the sector has not been read in a long time, and a latent error has been allowed to grow too large, error correction will be impossible and the drive When I ran Spinrite in my other 2 drives (from the laptops) it reported 0 ECC errors, all the counters were in 0 and these drives have been used for some Typically this is x1 , x2 , x4 , or x8 .

HPC people can also put this script into something like Ganglia to track memory error counts.
