Hail.. This happened to me twice now.. using different burners different OS and different media types of different brands... So.. Erasing a RW media somehow corrupts the disks filesystem making all my systems hang while the media is on the drive..´ This is what happened.. I erased the CD and no error message appeared.. then i tried to burn it and got a message that the disk couldnt be written. Now each time i put it in any of the drives of my 4 computers running either windows, ubuntu or openSUSE it slows my system and hangs any program trying to read the drive... I cant erase it again cause CDburnerXP keeps hanging when the disks are on the drive.. The first time it happened with a Mitsai CD-RW using my laptop's burner while running on windows 7 ultimate x64.. The second time it happened with a Sony DVD-RW using my desktop burner while running on XP Professional x86.. Using CDburnerXP 126.96.36.1993 on both machines Both the disks were trashed.. Is this a know issue? Any ideas how to recover my disks?
