I'm using InCD version 126.96.36.199 on my laptop. At this moment of writing, I have just experienced data corruption in my InCD DVD-RW. This is what I did:
I copied files to a DVD-RW that was formatted with InCD. The DVD-RW could not be ejected because it was still being written to. The laptop could neither be restarted nor hibernated because the writing was still in progress. The last time it took about 2 hours to write a DVD-RW before it could be ejected (I have a 2x DVD writer that writes to DVD-RWs at only 1x speed). Since I couldn't wait so long, I decided to pull the plug from the laptop and restart it. When I reinserted the DVD-RW, there was no data on it.
So you should wait until the disc pops out on its own no matter how long it takes. That's when all data have been written properly to it.
There's another thread in this forum that warns against the use of InCD. See http://club.cdfreaks.com/showthread.php?s=&threadid=53834. Because of the number of problems, I do not use InCD or any other packet writing software for archiving important data, preferring to use a burning program instead. I backup data on another hard disk, and archive on DVD-Rs using a DVD burning application.
