NOt really following you now. Maybe I forgot to mention that the only thing I did with the harddrives before running badblocks, was to wipe out the partition table, and create one huge LInux 83 partition but without creating a file system on it.
The -c option calls badblocks doesn't it? SO what is so different from what I did?
I would have thought that running "badblocks -vsw -c 10240" would be the best test I could get with the most reliable results.
Based on what you are saying, the 120GB disk that showed huge amounts of bad blocks, had run out of spares.
Instead, the 80GB disk, even though it probably has Bad blocks (that were identified as such by the RAID board) they were remapped to spares by the drive and therefore, cause the drive still has spares, the "badblocks" software doesn't see any bad blocks?
