Consider the following scenario:

• You have an x86 version of Windows Vista or of Windows Server 2008 installed on a computer’s IDE/ATA disk.
• The computer has more than 4 gigabytes (GB) of physical memory.
• The system is running in Physical Address Extension (PAE) mode.
• You configure the system to generate a memory dump file when a fatal system error occurs.

However, when a fatal system error occurs, and you receive a Stop error message, no dump file is generated. Or, an invalid dump file is generated.

When you run the chkdsk /r command or the chkdsk /f command to check a hard disk that is larger than 2 terabytes on a Windows Vista-based computer, the command takes a long time to run.

This problem occurs if the disk is an Integrated Drive Electronics (IDE) hard disk or Serial Advanced Technology Attachment (SATA) hard disk.

Consider the following scenario. You have a Windows Vista-based computer that uses an Integrated Drive Electronics (IDE) hard disk. On this computer, you query the transfer mode in Device Manager. In this scenario, Ultra DMA Mode 5 transfer mode may be incorrectly listed as an Ultra DMA Mode 2 transfer mode.
