I was trying to copy 90 gigabyte MP3 files onto this disc because I wanted a portable device for my music files. I can't even complete 5 percent of the copy without errors. I've tried copying from this device and I'm getting the same errors. All of my slower proprietary drives work fine. I think I'll go back and grab another Sandisk drive. It's worth the extra money when it comes to reliability. Don't let the high number of positive reviews fool you. This disc is garbage. I find it very strange that this device has so many positive reviews. Most of the negative reviews I've read follow the script of the errors I've encountered. Believe them! You can't rely on this drive.
