Excerpt: ... AO-12. If the tool creates image files, then it will create an image file of a source on a magnetic medium that can be removed from the platform on which it was created. Suitable magnetic tape removable media were not available. Small ( less than 250MB ) media, such as floppy disks or zip disks, were not considered useful for imaging hard drives and therefore, were not tested. AO-13. If the tool creates an image file from a source on a removable magnetic medium, then a duplicate of the source created from the removable magnetic medium will result in a duplicate on the destination, and the destination will compare equal to the source. Suitable magnetic tape removable media were not available. Small ( less than 250MB ) media, such as floppy disks or zip disks, were not considered useful for imaging hard drives and therefore, were not tested. AO-14. If an image file is created, and there are no errors reading from a source, nor errors writing to a destination, then a bit-stream duplicate created from the image file will compare equal to the source. The results for image files are included in the results for the mandatory assertions. The following test cases are for image files. Each line of the table describes one test case. The Case column identifies the test case. The Op column indicates the type of operation, either to create a copy of the source or to create and image file. The Src column indicates the type of interface used to connect the source drive to the test PC. The Dst column indicates the type of interface used to connect the destination drive to the test PC. The Rel Size column indicates the relative size of the source drive to the destination drive. All test cases with the Obj parameter value of Disk are operations on the entire physica...
