Hi,
I use Synctoy 2.0 to backup data to a DVD-RAM with 3x Speed (among other backup tasks). Most of the time I get a CRC error when data is transfered from a RAM-Stick to DVD-RAM, somewhere in the middle of the process. However, checkdisk tells me everything is OK. A second try results in a successful Backup or in another CRC error on a different file.
I have the feeling this error is due to a slow file transfer rate which SyncToy spuriously interprets as a write error.
