The installation of this driver is only required for systems running versions of SunOS 4. Disc Identification Each disc formatting project has associated files which hold information about the disc and how it is to be constructed. This file provides the program with identifying information required by the ISO format.
Fortunately, most of the information is not significant to the actual formatting process and can be ignored. In most current implementations this information is not even available to the user. Examples of this user provided file can be found in the application's project directory. The file used by the example given above is stored with another file, which more completely describes the general form of data input.
Many users will already have their file set organized as they want it to appear. This is usually the case for software distributions and other directory-structured data. These utilities are provided in source form and can be modified to suit a particular user's needs. These utilities carry no distribution restrictions if used in conjunction with MakeDisc.
Directory Depth As opposed to the entirely automatic handling of file name compliance, the depth of the directories must be controlled by the specific organization of the file set to be duplicated. Though the ISO standard only allows eight levels in the formatted directory structure, the original file set might have more. In order to be ISO compliant, the file set must be reorganized such that the directory depth does not exceed eight levels.
For systems with Rock Ridge support, MakeDisc can automatically remap directories, using symbolic links and the Rock Ridge extensions to reconstruct the original tree.
If illegal or inappropriate parameters are specified, one or more of the usage lines for the individual programs may be generated. Contact YMi, for more information. During preprocessing of the file set, if a directory is found which would appear at level eight in the directory structure of the image, an error message will be generated. The program will continue to scan for other possible depth violations before terminating without generating an image.
During the process of dumping the files to tape, the premastering software will check to determine if the file size has changed, or if the file has become inaccessible since the formatting process began. As with the directory depth detection, the file modification detection can be overridden. Multiple output images can be created from the same set of intermediate files without re-running MakeDisc by executing a subprogram, where each of the parameters are defined as with MakeDisc.
This allows you to create duplicate copies of an image to submit to a production facility. It can also be used to create a tape image of a file set which has already been formatted onto a hard disk partition for testing. This feature allows you to create tape images identical to the original without requiring a large amount of empty disk space or re-running the entire formatting process.
Operation Once provided with the location of the base of the tree to be duplicated, the program will reproduce each file and directory encountered.
Any branch of a directory tree can be specified. This branch may contain mount points for other file systems, as supported by the local system. Files and directories in these file systems are not treated as symbolic links, but are copied to the tape or disk image in the same manner as "local" files.
NOTE: No modifications are made to the original file set in this process By mounting additional files systems accessible either locally or over a network at mount points within the source directory tree, many small, distributed data sets can be included in a single source data set.
This can be any writable device or a file The outdevice size, the volume of information that one medium on the specific output device can handle. NOTE: The outdevice can reference a device on another machine on a network. MakeDisc, when executed, details the premastering process by displaying messages about the work in progress, errors, warnings or prompts as they occur.
These messages are also appended to a work directory. Contact YMi for more information. Disk2vhd Disk2vhd simplifies the migration of physical systems into virtual machines p2v. DiskMon This utility captures all hard disk activity or acts like a software disk activity light in your system tray. DiskView Graphical disk sector utility. Disk Usage DU View disk usage by directory. EFSDump View information for encrypted files.
FindLinks FindLinks reports the file index and any hard links alternate file paths on the same volume that exist for the specified file. A file's data remains allocated so long as at it has at least one file name referencing it. MoveFile Schedule file rename and delete commands for the next reboot. This can be useful for cleaning stubborn or in-use malware files.
PendMoves See what files are scheduled for delete or rename the next time the system boots. WIN file for native file access purposes, i. WIN files stand a chance of being able to read the files. This is the best option perhaps, but be aware of some potential difficulties:. WIN to be copied to the user's hard drive before use - e. WIN file from the CD for their use.
It is easy to tie yourself up in knots with this and best avoided if possible. Also, be careful in case the QXL. You will need to give some thought as to what filing system format you use to actually create the CD in the first place. There are a relatively small number of QLers who use each type of compatible system, but overall the total numbers of all systems combined make it worthwhile giving thought to using a "lowest common denominator" format that your CD creation software and the target systems can all use.
If your CD is aimed at one specific group you may be able to use a specific format which gives advantages such as long file names or deep nesting of directories.
There is such a format as ISO level 2 not too sure of the exact differences which relaxes some of these restrictions. But of course it relies on the target system understanding level 2, so for our purposes rather defeats the object of a 'lowest common denominator'. If you create CDs using the Joliet extended filing system e.
