I am working on a project for a client, 1080i/59.97 that was captured at 1:1.  Last night I moved the media from his system, a Symphony Nitris/PC, copying the MXF media from a Unity workspace into an AvidMedia/MXF/1 folder on a portable hard drive, along with the two corresponding bin files.  I loaded the media onto my Media Composer's HD and opened the Avid.  The databases rebuilt and everything was online except one 11 minute clip, the one that was in the second bin.  I was sure that I had copied all the media, but when I looked I couldn't see the relevant files in my MC drive or on the portable HD, so I thought that I had somehow missed copying them. It was late when I did this, and had just come off of a sixteeen hour job.  So I went back to re-copy them tonight.

When I hooked my hd up to the client's Avid, I immediately saw that the media files WERE there.  I persuaded myself that I had been so tired I had somehow missed the files and hadn't loaded them onto my MC in the first place.  But just in case, I consolidated the same files another time onto the hd from the client's Symphony project, making a third bin.  I checked the consolidated files in bin view and it showed that the media was on the portable HD.  (I confess that I didn't look at the media on the drive itself, but there is no other drive with this name anywhere in the system.)  Now that I am back at my system, I cannot "see" the files, the original ones or the newly consolidated ones, although the bin shows that it was last altered at 12:17am today, the point when I did the consolidation.

I do not believe there is any difference between the media in the two bins, but unfortunately I cannot go back to check until tonight, when I will have one final shot to acquire these files so that I can edit over the weekend and have something for the client on Monday morning.  Again, when I look at the portable hd with the PC, I see the files.  When I look with the Mac I they are missing.  BTW, all the media was captured from tape.

Thanks to all for any help.

Solved it!   After trying all kinds of search questions on the forum I tried "moving media from a mac to a pc."  Another issue I had was that my hd was originally formatted by a pc and I couldn't get permission to write to it from the mac no matter what I tried to do.  Someone posting here recommended NFTS for Mac OSX by Paragon.  It let's your mac see NFTS drives as OSX native.  I downloaded the trial version-that was it.  The files magically appeared, both sets, and I am transferring them now.  I was going to buy the download for $40, but really wanted the disc and ended up finding it on Amazon for $27 plus shipping.  These guys deserve the money!
