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.
