I have a large folder of data (mostly Office files) that I have attempted to burn on 2 different computers with different programs. The data transfers fine from disk to USB drive. On both PCs the burn seems to go fine, but when I put the DVD in the other computer it doesn't read. What could I be doing wrong?
What type of DVD media are you using? Are you sure the second computer is a DVD drive, and is is speced to be able to read the DVD media you are using? Most drives can read DVD+RW, some cannot. Newer drives can read DVD-RW, but there are lot of older drives out there that cannot.
Anyway, I'd say this is your problem. You are burning in a format that the second drive cannot read.
This is really a pretty common problem. Where I work, we burn a lot of DVD's for training and educational purposes. Every so often we get a call from a trainer somewhere who complains that the DVD's sent to them do not work. So we burn them a new set at DVD- and send to them. That seems to do the trick.
