I've just migrated everything from a previous computer running Vista to a new one running Windows 7. (I used Zinstall, if that's relevant.) This relettered my external drives. Rather than trying to move and rename within MC, I've dragged and dropped folders from Windows Explorer. On the first pass, this worked well. The files are clearly showing up in the proper location, and I've spot-played them. However, in returning to files on several drives in particular, they are no longer live - the yellow icon appears, and of course they don't play. I've repeatedly reinstalled by dragging from Explorer, the files appear to be live, I migrate away and when I return, they're defunct. This involves a large number of files, not a handful.
I've checked the drives in question, they seem to be in good order.I don't know of any problems with the files themselves. I did not run into this previously in Vista. Has anyone else encountered this, and if so, what are the solutions? I've searched around in Support and didn't find anything else that seemed relevant.
Thanks
