I don't think the HD is failing, but that's always a possibiliity. I use pretty good stuff (build my own computers), such as Western Digital Raptor drives, etc. It does seem like there is some corruption in itunes itself perhaps. I also store all the files for itunes on an internal drive different than the "C" drive. In fact, for My Documents, all that is stored on a "D" (internal) drive other than C as well. That keeps the drive more efficient. Lots of room, and better performance. I wonder if uninstalling i-tunes and reinstalling might make sense. I do keep backups on a regular basis of the i-Tunes Music folders containing the xml and other similar files itunes uses. I would backup the most recent itunes files and then ininstall itunes. Reinstall and then copy over the itunes music folder files (xml, etc).
Does that sound like it might help? I do see a coorelation between files that I burned and then edited using Sony Sound Forge Audio software. The only files that are misbehaving are files that have been touched there. That tells me that's where the problem resides. Yet, if I open up the songs in the Sony software, they'll play fine, and the full length, as they will in WMP or other player such as Media Monkey. So that's where I'm confused as to what the solution is. It might even be with the converter I use.
Generally, here's what I'll do to get files into itunes. (I rarely import them directly into itunes).
1. I'll burn a CD to wave.
2. Depending on the song or album, I may edit the end off to keep it tighter so there's no so much silence at the end of songs. I trim the 1-3 seconds you sometimes get after a song ends cold or fades. I used to use Audio Catalyst and could set it up so that it would get it really tight, but that software is so old I have to jump through hoops to get the software to work in XP. (I have Windows 7 but use XP with itunes and is my main computer. I like XP much better).
3. I'll then save the edited file to wave, thereby keeping a wave file of every thing I either burn or edit.
4. Then I'll use Creative Audio Converter to mp3.
5. I'll then use Tag & Rename ID3 tagging software to put artist/title on the file.
6. Then it gets imported into itunes.
In the future I may just burn the stuff into itunes, but I have much more control doing it as I do. With the wave files always saved, that's always my source so if I ever want to reconvert at a higher or different baud rate/type (mp3, aac, wma, etc), I can do that.
Anyway, do you see anything in here that gives you any ideas? And BTW, I never had any issue with the Sony software that I was aware of. It's only been recently. I'm almost wondering if it's an itunes software issue, but probably unlikely as if it were it would affect other files too.
Thanks again!!!
