Mdf Τι είναι και τι το κάνεις

[blkik]

Έχω ένα δίδυμο αρχείων Mds και Mdf το πρώτο το κάνεις mount με τα daemon tools το δευτερο όμως δεν το βλέπουν τι ρόλο έχει

[Snips]

Και αυτό το κάνεις mount αν θες. Είναι αντίστιχο με το .cue των .bin isos.

Θεώρησε το απλά ως "συνοδευτικό".

[blkik]

Εκει είναι το θεμα τα daemon βλέπουν μόνο το mds

[Snips]

ΑΝ επιλέξεις all files θα δεις ότι τα βλέπει και τα φορτώνει κανονικά. Στην ουσία όμως, το mds φορτώνει. Ακόμα και το alcohol που τα δημιουργεί δεν τα "βλέπει" στην λίστα αρχικά.

Η λέξη "συνοδευτικό" που είπε ο Snips περιγράφει ακριβώς αυτό που είναι. Απλώς χρειάζεται κι αυτό το αρχείο για να παίξει σωστά το image. Μην το πειράξεις.

What is a CD Image?

A CD image is essentially an exact copy of content of a CD stored within a single (or a few) files; the two primary uses of such images are (a) to 'mount' it onto a virtual-drive for improved performance or ( to create an exact replica of the original cd. Note that with respect to the latter, not all image formats are suited to the task of replicating CDs especially copy-protected ones and some formats are much better suited to the task than others.

ISO

The de-facto standard cd-image format most obvious as ISO is short for International Standards Organization, this format of CD image can be read anywhere in the world, on any hardware platform (capable of reading CDs) and by any operating system. This is the image format of choice if you wish to spread your data around as it also is one of the only formats to be totally self-contained (i.e., just a single file per image) as well as being one of the image formats with the smallest file size.

Naturally the universal acceptance of such a format comes at a cost: the ISO format is horribly inept at making proper 1:1 rips of any copy protected CDs as well as having the occasional hiccup with some of the more colorful CD profiles like Karaoke CDs and such. Being the de-facto standard, there is only one flavor of ISO files:

Mode1/2048

All ISO files will be of Mode 1 and contain 2048 bytes/sector (and compared to 2532 and sometimes more on other formats, it's not hard to see why ISO files are among the smallest)

BIN/CUE

This is the 'classic' image format and probably the second-most common if not the most common, the BIN/CUE format was defined by Goldenhawk Technologies and of the two files, the 'BIN' file is the important one: you can generate a CUE file from a given BIN file using any of the various tools however the process cannot be reversed. If you have a CUE file but no BIN -- you are out of luck.

Almost all CD burning applications support reading BIN files without the CUE file however many will ask you to define some specifications of the BIN file (as that was the role of the CUE file, to define the specifications of the BIN in order for the application to properly interpret it). Compared to the ISO format, the BIN/CUE format stores a significantly greater amount of information per sector (2352 bytes instead of 2048) and this extra information allows for error detection/correction etc. BIN/CUE images are generally split into two major categories (there are others but they are horribly obscure and often involve seemingly random combinations of included sub-channel data):

Mode1/2352

Used for any type of DataCD image and although there are exceptions, they are few and far between; if you've got a DataCD image, odds are it will be a Mode1/2352.

Mode2/2352

This sub-format is most commonly associated with multimedia images most notably VideoCD and SuperVideoCD images.

IMG/SUB/CCD

This format was introduced by Elby (now Slysoft) in their highly successful product, CloneCD. What makes IMG/SUB/CCD different from the 'big two' (ISO and BIN/CUE) is that, while you can make a 1:1 backup of protected CDs with BIN/CUE, they are inept at making perfect backups for more advanced protections, especially with protections that make use of the various subchannels available on a CD such as SecureROM. The IMG file stores the important data and the SUB/CCD files specify how it is to be interpreted.

MDF/MDS

The MDF/MDS images used by Alcohol120% is an extremely effective format for both general purpose ripping as well as specialized copy-protected ripping. Very similar to the BIN/CUE format, the MDF/MDS images are especially tweaked for making exact dumps of CDs. The MDF file is the one containing the major data and the MDS file specifies how it is to be interpreted as well as storing the copy-protection information required for making 1:1 backups.

BWT/BWA

Used by VSO's Blindwrite CD imaging program, the BWT/BWA files are especially dedicated for making perfect 1:1 duplications of copy-protected CDs. The BWT file contains the major information while the BWA file provides the data required to properly read it as well as required copy-protection information.
