John Beardsworth's Lightroom plug-ins....

[Mathew Farrell]

Here's another one for you John:

A way to search out corrupted images, ideally removing them and re-importing them. Renaming, keywords, etc might be a bit ambitious.

As an example, I've recently been finding a bunch of images at random that have been corrupted somehow upon import/convert to DNG (or perhaps at a later date. Hard to say). The easiest solution is to delete them via LR, then import images from the appropriate backup folder (LR's import backup - RAW format, no renaming, etc). I then rename and re-keyword (etc) manually.
The most useful feature would be hunting out and grouping corrupt images.
