Running file against corrupted RRDs has worked for me in the past.
Valid RRDs will show up with "RRDTool DB version 0003", while
corrupted ones will show "data".

Something like:

find /path/to/collectd/rrds -name '*.rrd' |xargs file |grep ': data$"
|cut -d ':' -f 1> ~/corrupted.txt

will give you a list of potentially corrupted files.
