Hi, I'm a long-time user of dbpoweramp/CD Ripper and although I rarely purchase CDs nowadays I do have around 850. These have been digitised differently as my thinking and budget provided. I started with 128kbps MP3, moved to 160kbps WMA and then WMA 9.2 lossless. My naming strategy has also eveolved over the years. I decided I'd re-rip everything in lossless format using consistent naming but I'm getting what I consider a high number of AccurateRip errors, around 1 in 10 CDs either fails or is Securely ripped, often multiple tracks. The disc surface is unmarked; most of these CDs were only taken out of the jewel case, ripped to disc and then put back away for storage. I know writeable CDs have a limited shelf life, but these are commercial pressed CDs. Do pressed discs also degrade over time? To be fair, many of these CDs were purchased in the 1990s. Thanks.
