Converting cda to mp3

[qanda]This thread is about the Western Digital 200 GB External Combo 7200RPM Hard Drive - FireWire and USB 2.0 / 1.1. Click here to see full specs[/qanda]Hello ClubFreak,
My first time to the Site and hope your assits will be of great help. Trying to convert my CDA files to MP3 seems fine but only when I insert a CD into my CD/DVD drive. Whenever I try retriving from a folder on my C drive or another location I have no succes in converting my files. I have tried several times without any luck. Please give me your help or what software I should use.

Thanks RAS

What program are you using to convert? What type of files are you trying to convert from your hard drive (what extension do they have)?
