You could use something like monit, set the poll frequency to 60 seconds or so. You could either script something to act on the alert, or have monit execute a script to do the wiping.
For wiping the disk I would use badblacks (with the -w flag) and logging the output. Easier than parsing syslog for errors after using dd or something similar, also badblocks can output a file that can be used by fsck.
