iTunes Import Error - Folder Can't Be Found

[Traverse]

I am attempting to re-rip my CD collection in Lossless format by replacing the AAC files in my iTunes library, but each time I try to import one I get an error that the "Folder Can't Be Found." It's happening on random songs across multiple disks, the disk disappears, and then re appears. Is this a problem with iTunes or a problem with the disk drive?
[doublepost=1452390709][/doublepost]It won't import on my Windows partition either, but it WILL import on my mother's Mac mini where iTunes has never been used. Ugh.

You used one of those CD/DVD head cleaner disks on your drive?
Your problem sounds a lot like a dirty read head.

I'm convinced it's more of a software problem because it works with a different mac running the same OS

Ohh, external drive then? Didn't see that in OP.
You've checked the "Use error correction when reading Audio CDs" in the "Import settings" dialog of iTunes General prefs?
I've had that work for me on a cranky CD or two.

Might be a bad cable or a hub problem on that Mac.
