This is kind of a complex situation, so bear with me as there are a lot of variables here: I've got an NTFS formatted disk on a Mac Pro with Windows XP Bootcamp. Windows is installed on a separate disc partitioned as Bootcamp (300 GB), and Mac OS Extended (Journaled) (700GB). Mac OS is on the original disc that came with the Mac Pro. I'm also using Tuxera to give me read/write permissions on the NTFS disk on the Mac OS. I have had a minor problem with the NTFS only disk that resulted in having to reformat the entire disk recently. This NTFS disk is now dedicated as nothing but music file storage, with iTunes using it as it's primary library, from both the Windows and Mac OS's, but only the Mac iTunes is organizing the files, so I use that iTunes installation only to add new music files, fix tags and artwork etc. On the Windows side, I just add the new files after they've been added on the Mac side, and fix some tags and artwork don't get "picked up" Windows iTunes. The problem I'm seeing is a typical one reported by a LOT of iTunes users. Quite a lot of files are being reported as missing by iTunes. They're not missing. Every one can easily be relinked straight in the library on the NTFS disk. Now I have a script from Doug's iTunes Scripts installed (that I have not used yet), that's supposed to relocate "missing" files. Of course it only works on Mac, but that's okay because oddly, the missing file problem is much worse on the Mac OS than it is on Windows. This is a HUGE music library, so I'm not too surprised at seeing this problem, and am prepared to have to maintain it more so than a library of, say, less than a thousand files. The instructions that come with Doug's script recommend a couple of things before running the script: Repair Permissions. Setting iTunes as default player for all music files. I HATE the second option because I tend to check a lot of music files before adding them to iTunes to make sure they're good, and having them play in iTunes automatically adds them to the library before I'm ready. If I have to do it, I suppose I have to, and will have to remember to right click and "open with" another application, which is a royal pain because my stupid mouse tends to double click to easily, opening them in iTunes anyway, but "it is what it is," I suppose. The first step also concerns me because this is not a Mac disk. Does anyone know if running "Repair Permissions" from the Mac OS might cause any problems with an NTFS disc? Would it be better to boot in Windows and run Disk Check? Also, if anyone has ever used this "Doug's Script" on an NTFS disc, do you have any insight as to whether there are any problems doing so? This is the script I'm talking about: http://dougscripts.com/itunes/scripts/ss.php?sp=itunestrackcpr Any advice would be greatly appreciated.
