iTune screwing up WAV file data?


I am not sure if i'm doing something wrong or I'm just stupid...

When ever I whip out my computer to start fresh, iTune screws up my WAV files. All WAV files would only show up with track number, song name. All other info is deleted...(such as album name, artist, comments, etc..)

And the only way i know of to get all that info back is to re-rip EVERY CD... It's very time consuming. Made me stomp around the house, slamming doors, and almost made me cry.

Is there a correct procedure to back up all the info on WAV files? (I guess that's called metadata?)

I haven't tried it (because I'm affraid that I might be wrong) really dont want to go through all this again. But am I suppose to File--> Export...--> and save the Music.xml file. Then when I have to start fresh again, go to File--> Import.

But is that before or after I choose "Add Folder to Library"??

I hope I'm making sense...

I'm curious to what you guys mean my not tagging it correctly? I've been torn among which format to use as I want the absolute best sound into my 2-channel system and don't use the library for my iPod. Storage space is a non-issue. Therefore I thought I'd try wav. When I ripped, I got all of the track names, artist, album, etc. to come up just fine in iTunes. Am I missing something?
Jkscherk,
I'm talking about when there is time that you have to reinstall everything, or when you buy/build a new computer. And when you try to put the WAV files back in, most of the info gets deleted.

Everything is good when ripped.
Oh...Now I get it. In that case, I guess you're reliant on having to reuse the same hard drive, or have the drive mirrored in a backup.

It also seems to me that depending on what hardware you use for reproduction, you should chose the file format accordingly. Squeezebox and you go with FLAC; AppleTV and you go with WAV. Would that make sense?
You can't "tag" .wav files in iTunes. That is the major disadvantage with this format...and you can't play it on ipods either.

You can play wav files on ipods. I'm doing it right now. But on the pc side, I use jriver which let's you tag wav files. Personally, I stayed away from itunes -- I believe it doesn't make bit-perfect rips and in my experience the playback is not as good as other players, like jriver and foobar. Your mileage may vary.
