Disk-Image Transfer Utility Backup Utility Usage: DITU Purpose: Copy disk sectors into a file, or vice versa Options: Source and Target must be either ... : - Where is the BIOS disk number - is the disk geometry in :: format - Examples 0:80:2:18, 1:40:2:9 - File or path name of the disk image - The filename should NOT start with a digit - File extension of IMG will be assumed - Examples FLOPPY, FLOPPY.IMG Source and Target may not be the same type of media. Examples: DITU 1:80:2:15 ROOTDISK Copies the entire disk (1.2 Mb) from drive B: to a file called ROOTDISK.IMG DITU NET$DOS.SYS 0:80:2:18 Copies the contents of the file NET$DOS.SYS to the 1.44 Mb disk in drive A: DITU SYSTEM 128:160:4:18 Copies 160 cylinders of data from drive C (the first hard disk) into a file called SYSTEM.IMG. The hard disk has 4 drive heads per cylinder, and 18 sectors per drive head. Responses: Specify Source and Target parameters Not enough parameters were specified on the command line. Check the usage and try again. Transfer type must be disk-image or image-disk Wrong kind of parameters were specified. Transfer can only take place between disk and file, not between two types of the same media (ie, disk-disk and file-file are invalid). Source: BIOS Drive: 0 [80:2:15] Target: Image File: FLOPPY.IMG Ready to start copying. Press Enter to start, or any other key to cancel. Copy aborted User did not press Enter when asked to verify parameters. open() failed Unable to open the image file for image-disk transfer. Check that the path is correct, and that the file exists. creat() failed Unable to create image file for disk-image transfer. Check that the path is correct, and that you have write permission. write() failed Unable to write data to the image file. Usually caused by the storage space running out. Copy aborted: Too many errors Copying exceeded the error threshold (set to 18 errors). Copy Completed with x errors Copying completed, but errors occured during the transfer. Partial Copy Complete Image file was copied successfully, but it was not long enough to span the entire target disk. Copy Completed Transfer completed successfully.
