Over the past few weeks I've converted my entire (store-bought) CD collection to .flac files, both for backup purposes as well as easier playback. Several of the CDs featured copy protection, but I was still able to convert them by various methods (different cdrom/dvdrom, different software, different OS, etc...).
Alas, there is one double-CD which I cannot convert, and I'm at a loss as to what I should try next to create a .flac version of it. As soon as I enter the CD into a drive, the drive starts spinning up, stopping, clicking, and repeating the process. After a while, tools such as Exact Audio Copy or CDex show a list of 11 data tracks in one session (for both discs), which cannot be ripped.
Does anybody have any suggestions on how I can create a backup of this CD?
There are some things I'd like to clarify upfront:
- yes, I own the CD (I've bought thousands of them in the past), and I can prove it
- in my country it is legal to create as well as own a backup copy of store-bought media
- I cannot buy the CD online - iTunes, Spotify, you name it: they don't know this CD (apparently half of my collection is "unknown" to both)
- I cannot contact the record company or record label, both are out of business
- the CD plays perfectly on ANY audio player, but cannot be played on a PC - I've tried my 8 Windows machines, a few Linux machines and a Mac.
- some CDs I had, had an extra track containing data or an executable to defeat copying/ripping - this is not the same type of protection
- other CDs had a little black ring near the edge as protection (basically also a data track), this CD doesn't.
Besides making a backup copy of my CDs, I'd also like to know exactly HOW they did this. I have never come across an audio copy protection scheme that wasn't easily circumvented, so this one really puzzles me, and as a software developer, I'd like to know the details ;)
Thanks in advance!
