Why would itunes strip data from .wav files? 3 Qs:

Friends,

Turns out I did not lose metadata, only data. But I am having a meta-bummer ("a bummer about bummers") as a consequence.

Three months ago, I began to store itunes music from a large CD collection on an outboard 500 GB WD hard drive. Lots of good advice here at Audiogon re: how to hi fi a computer system. Audiogon posts, along with some generous consults from veterans, led me to buy a second hard drive (also a WD, but bigger at one TB), along with a Squeezebox, and an Ipod.

I have been slowly ripping CDs to itunes, and had about 3,000 songs as .wav files. I plan to convert them to ALC in a Smart Playlist once my Ipod gets full.

When I copied HD#1 contents to HD#2, both hard drives dropped artist, album, genre, composer and showed lots of "can't find the path" exclamation points (!).

With help from several Audiogon users I have successfully recovered my .wav files and reduced !s. (delete Library, Import Folder from HD#1 titles 'itunes music'). But everything appears as a song name only.

QUESTION #1: CAN I FIND THE MISSING DATA? IS THERE A SEARCHABLE FILE EXTENSION? OR DID THEY SIMPLY DISAPPEAR?

QUESTION #2: THERE SEEMS TO BE NO ALTERNATIVE TO RE-RIPPING HUNDREDS OF CDS BY PHYSICALLY PLACING THEM IN MY PC'S CD DRIVE. (NO ONE DESCRIBES A PROCESS OF SIMPLY SENDING CD DIGITIAL OUT TO LAPTOP AS A PCM STREAM.) IF I HAVE TO GO THROUGH THAT LIVING HECK AGAIN, HOW DO I AVOID A RECURRENCE OF THE DATA LOSS DURING BACKUP?

QUESTION 3: Apparently because I use an external HD, I have to disable error-correction when ripping in itunes. I am not too computer facile (this may already be apparent), but as long as I am taking the time, I would like to invest a few more minutes and use error correction in itunes. (I am not ready for EAC yet.) Can it be done?

Thanks to all of you who posted and emailed.

Cheer,
