JSI Tip 9421. When you attempt to access the contents of a mounted disk image, Windows Server 2003 SP1 issues a 'Data error'?

When you use the ADS (Automated Deployment Services) imgmount command, without the /w switch, to mount a disk image in read-only mode on Windows Server 2003 with Service Pack 1, you receive:

Data error (cyclic redundancy check)

To workaround this bug, use the /w switch to mount a copy of the image in read/write mode:

imgmount /m /w ACopyOfTheImage.img

After you are finished using the copy, you can delete it.

Microsoft Knowledge Base Article 891373, Your image may be corrupted when you try to un-mount it with the ADS Imgmount command-line tool, Describes a problem that occurs when you un-mount an image after you perform some write operations on the image. In this case, it may be corrupted.
