I installed a hardware raid some time ago for backup/security. One of the
disks became corrupted and the other dutifully mirrored the corruption.
I'm not a geek, so I questioned the manufacturer of the raid card and they
simply told me that raid copied whatever was there! Huh?

Does anyone have any comment about this?

For the record, now I use a combination of rsync and CD burning.
