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.

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.

Update After beating on it for a couple of days, I did the IgnoreECC bit and it rebuilt, but my data is hosed.

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.
