Another complicating factor is that the more ECC bits included, the more processing power the controller must possess to process the Reed Solomon algorithm. If the unit is non-redundant a unit file system check is recommended. have a peek here
Update After beating on it for a couple of days, I did the IgnoreECC bit and it rebuilt, but my data is hosed. Post recovery, the president decided that perhaps we could spare enough for full redundancy. This is not in dispute. Thanks for your time. Homepage
Is this a safe assumption? The disk reserves some space which is used to replace bad sectors that appeared somewhere on the drive, without even notifying the OS (the HDD controller handles that transparently).

Thanks everyone for the help! Ecc Error Rate Fail I was in a nasty spot for a while then figured out that I could power down the machine and pull the disks one by one looking up the serial number Can 'it' be used to refer to a person? Back when 9GB was a big SCSI disk, it made sense to do RAID-5 and rebuild in 30 minutes.
Under Windows, right-click on your drive icon and choose Properties> Tools> Check Now. None of the drives have failed and thus there was no drive rebuild, so I assume that 3ware discovered a bad sector when it ran it's weekly auto-verify scan of the Ecc Error In The Probe Filter Directory With twelve terabytes you have to pull it six times! Ecc Error Hard Drive posted 3 years ago About the only way to reliably fix bad sectors on a hard drive is to run the drive manufacturer's sector verification utility which will examine each sector

You should set up scheduled verify of the array to catch unreadable sectors earlier, so that you can replace a drive which just started going bad. Is it a fallacy, and if so which, to believe we are special because our existence on Earth seems improbable? You can be sure I labelled them! 3ware Degraded Drive There are several different types of error correcting codes that have been invented over the years, but the type commonly used on PCs is the Reed-Solomon algorithm, named for researchers Irving

Wrong password - number of retries - what's a good number to allow?
What I can't tell is if I've just suffered a double-disk failure (bummer!) or if I'm reading this wrong. I replaced it.

They have been chosen because they are easier to decode than most other similar codes, can detect (and correct) large numbers of missing bits of data, and require the least number Maybe we've had bad luck, but I am now surprised when an array rebuilds without incident.
