ITunes Folder on Time Capsule missing after MATCH

Question

  To Start, I will explain my set-up.  I have an Extreme, connected to my Cable Modem, in my Computer-Room, which is hardwired to my primary Mac Pro computer.  I then have the Extreme wirelessly bridged to my Time Capsule, in my Family-Room, which is hardwired to my Mac Mini, which is in turn hardwired to my TV.  I also have a Macbook Pro in the down-stairs Bed-Room, an iPad in the up-stairs Bed-Room and an iPhone in my pocket, all on the Wi Fi network.  I keep my iTunes, iPhoto, Mail, etc., data files on the Time Capsule and have links on the other devices so that each App on each Computer retrrieves the data files from the Time Capsule (only problem is that only one computer can pull the data at any given time, which is not a problem for me).  All worked great until I ran MATCH on my iTunes library.
  MATCH itself seems to have worked well enough, though I did have to run it a few different times to get all the music uploaded.  My library is pretty large, so I am not real sure yet if EVERY thing got uploaded, but it appears that it did.  But afterwards I recieved errors and now my iTunes folder is missing from the Time Capusle, though the disk space appears to be still taken up.  Not only that, but I can not seem to write to the Time Capsule at all, and although I have been able to copy some of my data from the Time Capsule, some I can not.  I was able to copy the Mail folder from the Time Capsule to the Mac Mini, but I keep gettings errors when I try to open Mail on the MAc Pro, then Mail shuts down.  I downloaded all the Music from MATCH to my MacPro, but it is just the Music, not the Movies, Videos, etc..  My iPhotos will not seem to copy.
  I have not figured out any way to run any kind of Disk Utilities on the Time Capsule and do not have any idea what I can do other then wipe the disk and start again.  This is a 2 TB unit and my second Time Capsule, the first was returned to Apple due to other problems.  I have never used it to do backups, just as a NAS, though I do have most of my data copied onto other drives.  I am sure I will loss some data and will spend a lot of time trying to rebuild, if I can't do something with the Time Capsule.
  Any body with any ideas?

To me, it acts like the external drive "went to sleep", but i'm pretty sure that's not the case. Nor can i find any place in Mac OS/X to control that other than the power settings, and all my hardware is set to NOT sleep.
Chances are pretty good that the "sleep" function for this drive is built-in as part of the drive's firmware and you will have little or no control over it. Most drives do incorporate this "feature."
The other odd thing is that I have a fairly extensive set of Sonos music servers around the house which access that same music drive on that same time capsule.. and it NEVER loses access to anything... could be because Sonos doesn't use the iTunes library to access the music.
As you probably are already aware, iTunes is basically composed of two parts: 1) the iTunes Library, and 2) the iTunes Media. Typically these are both stored within the user's Music folder, but they can be in totally separate locations.
I'm not 100% sure, but I don't think Sonos relies on the iTunes application, but instead, will access media files directly ... in this case, the iTunes Media files located on the hard drive connected to the TC.
