I am trying to run the game ""Wiggles"" to test the directX capabilities of VirtualBox 3.0.4. I was able to install the game. But it will not run. When tracing the events generated by the program with procmon (sysinternal tool) I see the following messages. 30 17:24:21,4468176 Wiggles.exe 564 DeviceIoControl D: SUCCESS Control: IOCTL_SCSI_PASS_THROUGH_DIRECT 30 17:24:21,4792606 Wiggles.exe 564 DeviceIoControl D: FAST IO DISALLOWED Control: 0x24004 (Device:0x2 Function:1 Method: 0) 30 17:24:21,4792835 Wiggles.exe 564 DeviceIoControl D: IO DEVICE ERROR Control: 0x24004 (Device:0x2 Function:1 Method: 0) The program ""Wiggles"" tries to access the DVD drive but seems to be refused some operation. Attached is the logfile ""Logfile.XML.gz"". The logfile ""VBox.log.gz"" of VirtualBox is attached too. It indicates two cdrom related errors. 00:00:04.453 PIIX3 ATA: LUN#2: CD-ROM passthrough cmd=0x28 sense=2 ASC=0x3a ASCQ=0x1 VERR_DEV_IO_ERROR ... 00:05:04.678 PIIX3 ATA: LUN#2: CD-ROM passthrough cmd=0x5a sense=5 ASC=0x24 ASCQ=0x0 VERR_DEV_IO_ERROR ... I do understand that the passthrough feature is fairly new and the incident report is just to notify of the occurred situation in the hope that it helps you to improve the VirtualBox, which is really an exceptional product.",defect,closed,DVD,VirtualBox 3.0.4,obsolete,,,other,Linux
