Renaming the one it's using started showing a difference, so I'm running the rsync -delete now to fully update it and then I can go from there. However, when I did the rsync from dev disk to EFS, I didn't use the -delete flag so there are old images there that are causing the wrong latest thumbnail to be shown in the file history. To synchronize images from live to dev, I have to do live EFS -> live backup disk -> dev backup disk -> dev EFS.

UPDATE: Just discovered at least part of the problem. The top thumbnail on the dev page is referencing an image file that doesn't exist but I'm not clear on where in the database that file is referenced since the databases and all images are identical. FWIW I did verify the image has the same checksum value on both the dev and life EFS filesystems.ДЇurther, since the dev and live databases are now identical, I'm unclear on where the incorrect current dev page information is getting that wrong entry.Д®DIT: I just noticed the mention of image metadata at the bottom of the live image page but not on dev, despite the image files being identical. And while the image in live looks correct (the user tried to change the image to see if that would help deleting it), the dev version shows the same image but with the image dimensions of the dev page's current image (203x718 vs 442x577). Note that the only real difference is in the current/top row of the pages' file history sections. See this album, the top image is the dev version and the bottom image is live, which you can directly view here. However, the page in question shows inconsistent file history pages for the image in question. I've backported my live wikis to dev (through mysqldump and import and nfs filesystem rsyncs) so they should now be identical.

Any recommendations/suggestions on how to correct this page so it can be updated with a new image (which is how this got discovered in the first place)? It seems that the invalid entry is somehow preventing the deletion. Go to Start menu and select Control Panel < Appearance & Personalization. I have no idea why the dev wiki is so completely different from the live one and whether that is related to this issue.ДЄll deletion attempts to date have failed, including after changing the image as the last revision of the page shows. Strangely, I have a dev version of the wiki that is a snapshot of the database from a few months ago but the dev wiki version of the page shows no change history and the image is the original from 2007, and a different image from the 2010 one showing in the live link provided.

Hire professionals to help when corruption is caused by hardware failure turn to Power Data Recovery when it is caused by software failure.

So we must recover corrupted files in different ways. A drive is commonly corrupted due to two kinds of reasons: hardware failures and soft failures. The file's history shows a missing entry but in the database the corresponding entry looks identical, including the timestamp, to its parent entry right below the missing one.
