How to find corrupt media...Need Level 4 helpers Please!

Question

Thanks for reading. There's alot of info here so thanks ahead of time!
I am at a post facility and don't have authorization to do some of the things mentioned in other posts so I need some expert recommendations (You all) in order to convince the "Post Production Facility Manager" to fix this.
I'm working on a project that, once I quit at night and re-open in the morning...Final Cut crashes/quits at about 22% on the progress bar.
My best workaround so far has been exporting the timeline/sequence as an XML and then re-importing into a NEW project. I do this because I usually have to go back 2 to 3 hours in the Auto Save Vault to find a project that WILL open.
I've also deleted all the renders, removed my Boris 4.2 transitions, deleted preferences...except that I hop from bay to bay as I also get shuffled around this facility too (which adds extra fun to try to get autosaves)
BACKGROUND: There are two systems that are intels and 2 that are G5s and we're all sharing an XSAN. Plus the "Facility Manager" also 'shares' the Raid (mounts the raid through one of the computers) while doing After Effects work from time to time (he renders on a system with the fiber card though).
Anyhow...in AVID MC land...if you watched at the point the progress bar stops...that gives you a better indication which/where you corrupted media file is.
There's more but I get back to it. Any ammo to use on the "Facility Manager" would be greatly appreciated as he is insistent on NEVER restarting the XSAN as it takes a half hour to restart...apparently....and he says that's not the problem.
Thanks,
Tom

Answer 1

<<Can you not navigate to the capture scratch folder on the x-san and re name it?>>
No, because there are 4 other editors using the Xsan and I don't/wouldn't get permission. What if I just 'Select All' on the timeline and Shift + D-it, take it offline, leave on the drive, and then reconnect?
Plus, when I reconnect in sections, what do I do to check for corrupted media? Would I find it by playing the timeline or am I opening and closing the project each time I do a new section
<<I will be willing to guess that the corrupt file is one of the following: a cmyk photoshop file, an imported stock shot or some other graphic file.>>
There are only five RGB 8-bit png's in the timeline. No CMYKs. No imported QTs. No stock footage. No mixed formats. Everything is DVCPRO HD 720p60 footage digitized through the KONA 3 card.
