I'm about to start ripping my entire CD collection with EAC. From there, the WAV files will be converted to Apple Lossless via iTunes. At this point, the WAVs will be deleted and the ALE files archived to DVD.

So I started thinking, what if I need to decode ALE back to WAV? I'm putting complete faith in iTunes that it will be able to restore the WAV files, just as if they were coming straight from EAC.

I had the idea to create an MD5 checksum of the WAV files right after I ripped them from EAC. I converted the WAVs to ALE, deleted them, then encoded the new ALE files back into WAVs with the iTunes WAV Encoder. When I ran the MD5 I created with the WAVs from EAC, it found no errors on the WAVs that had been converted to ALE and then back to WAV.

This would make them an 100% bit for bit perfect digital match, would it not? It would seem this would prove absolutely nothing was lost in the ALE conversions. Is this being way too paranoid keeping these MD5s hanging around with the album archive, or do you use similiar methods to check your own files? or is there a better way to do what I'm attempting?

Basically, at the end of the day, I just want to be sure that if need be, I could have exact copies of the WAVs that were ripped from EAC.
