It was then that I realized that dealing with failed drives in RAIDs is the IT equivalent of bomb squad duty. With twelve terabytes you have to pull it six times! When a sector is written to the hard disk, the appropriate ECC codes are generated and stored in the bits reserved for them. When any write is made to the disk, the ECC and checksum data for the sector is also updated.

Ah well you. As such, the recovery of the ECC data that is associated with the former write is also randomly distributed. permalinkembedsavegive gold[–]hateexchangeatheist, unless restoring backups[S] 1 point2 points3 points 2 years ago(0 children)i did not.

For redundant units, this typically means that dynamic sector repair has been invoked (see message 0023 Sector repair completed).
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 3ware Ecc Error ZFS can work around read errors -- if ZFS detects a bad sector on the drive, it will simply mark that sector as bad and never use it again. When the sector is read back, the user data read, combined with the ECC bits, can tell the controller if any errors occurred during the read.

For a laptop, my recommendation is to get another hard drive and use a drive imaging tool to move you existing data to the new drive. They are highly useful for migrations and disaster recovery. We purposely degrade them when new in order to show everyone what to do if things go wrong.
