SYMPTOMS
You can use the IOCTL_ATA_PASS_THROUGH structure or the IOCTL_ATA_PASS_THROUGH_DIRECT structure to send raw ATA commands to disk drives in a program. The ATA_FLAGS_48BIT_COMMAND ATA flag is introduced to enable 48-bit Logical Block Addressing (LBA) support in these structures.
However, if you set the ATA_FLAGS_48BIT_COMMAND ATA flag in these structures, the returned PreviousTaskFile member in the ATA_PASS_THROUGH_DIRECT structure or in the ATA_PASS_THROUGH_EX structure is incorrect in Microsoft Windows Server 2003 or in Microsoft Windows XP.
CAUSE
This problem occurs because of a bug in the Atapi.sys file. The bug causes the PreviousTaskFile member to be populated with incorrect data.
