SCSI Pass-Through Mode Sense Command May Crash the Computer
Article ID: 813908 - View products that this article applies to.
If a SCSI Mode Sense command (operation code 0x1A) is sent by using SCSI pass-through to an ATAPI CD-ROM device, you may receive a "Stop" error message on a blue screen and the computer may then stop responding or may restart. This may occur if the value of the Data Length field in the Mode Sense command is less than 8. Note that this problem occurs only with the 6-byte Mode Sense command (operation code 0x1A), not with the 10-byte Mode Sense command (operation code 0x5A).
This issue is caused by a problem in the Atapi.sys storage port driver.
