Differences between .img and .bin

[BesmirG]

I created an image of a CD (game, for testing purposes only, lol) I own, and since I am new to these image formats (bin, img) I tried to compare them. And the results I am going to show you are different. So:

 

This is the CD information:

 

MATSHITA DVD-RAM UJ-841S 1.60 (ATA)
Current Profile: CD-ROM

Disc Information:
Status: Complete
Erasable: No
Sessions: 1
Sectors: 288,502
Size: 590,852,096 bytes
Time: 64:08:52 (MM:SS:FF)

TOC Information:
Sesion 1...
-> Track 01  (Mode 1, LBA: 0 - 254306)
-> Track 02  (Audio, 03:06:61, LBA: 254307 - 268317)
-> Track 03  (Audio, 02:06:48, LBA: 268318 - 277815)
-> Track 04  (Audio, 02:22:36, LBA: 277816 - 288501)
-> LeadOut  (LBA: 288502)

ATIP Information:
Start Time of LeadIn (MID): 97m28s22f
Last Possible Start Time of LeadOut: 74m20s01f

 

This is the Cue file for .BIN.

 

FILE "B.....T.bin" BINARY
 TRACK 01 MODE1/2352
INDEX 01 00:00:00
 TRACK 02 AUDIO
INDEX 00 56:30:26
INDEX 01 56:30:57
 TRACK 03 AUDIO
INDEX 00 59:35:43
INDEX 01 59:37:43
 TRACK 04 AUDIO
INDEX 00 61:42:16
INDEX 01 61:44:16

 

This is the Cue file for .IMG.

 

FILE "B.....T.img" BINARY
 TRACK 01 MODE1/2352
INDEX 01 00:00:00
 TRACK 02 AUDIO
INDEX 00 56:28:57
INDEX 01 56:30:57
 TRACK 03 AUDIO
INDEX 00 59:35:43
INDEX 01 59:37:43
 TRACK 04 AUDIO
INDEX 00 61:42:16
INDEX 01 61:44:16

 

In Track 02, the INDEX 00 is not the same.

My question is, which of these ones (.BIN or .IMG) is closer to the original CD?

Then, 1. Please tell me where can I find some further info on these two formats?

2. The CD contains many tracks. Does this mean the CD is protected (just by looking at the tracks, and that it is a Game)?

It doesn't matter which file extension you use, the content and CUE should be the same for both.

 

You've just got a different pregap size in track 2 there, that's all.

 

Did you read the disc in the same drive? It's odd that it should return such different info - a few sectors/frames, maybe... but not that much.

 

There's nothing unusual about having some audio tracks after the data one on a game. It'll just be the in-game music.

Hi LIGHTNING UK!

 

Of course I used the same drive for reading the CD, and that's why I posted here: how is it possible to have two different results with the same drive, with the same CD, but with different image formats? Does this mean that my drive may some other times not be accurate, e.x. when copying or burning?

 

I mounted both the images in Virtual CloneDrive (by elby) and when I looked at them in ImgBurn there were no AUDIO tracks. Why is that? In the Cue there are certainly AUDIO tracks.

Try Daemon Tools

[BesmirG]

Daemon Tools was my favorite before. But since they introduced that toolbar and some bugs which conflicted with my PC, I uninstalled it. But let's see what happens; I am downloading it now.

 

Regarding the images above: Which one is more correct? The one with "INDEX 00 56:30:26" or the one with "INDEX 00 56:28:57"?

[Cynthia]

The toolbar is now only an option and not installed even if you didn't want it to be, as in the old version.

[LIGHTNING UK!]

It's impossible to say which is more accurate, you've only included the 2 examples.

 

Use the 'Media Information' screen to repeat the test a few more times.

 

Having said that, the others have a 2 second gap so I would guess the first should be 2 seconds too.

 

Within the program there's no difference between the file extensions - the cue should be the same (allowing for the drive to mess things up). Hell, you could call it *.george for all it cares.

[BesmirG]

Thanks to you, mmalves, Cynthia, and LIGHTNING UK! !

 

When mounting with Daemon Tools I can see the main track and the audio tracks in ImgBurn. However, now my only concern is about the drive, and it's accuracy. What about some of my questions above (edit, where can I find some other info on these two image formats, are these formats good for backing up my actual CD)?

Just google 'cue files'.

 

As I've said twice already, the extension you give the file containing the actual data is neither here nor there.

 

cue/bin is probably THE format for CD images - but it doesn't make any difference if it's cue/img or cue/iso... they're all the same thing really.

 

If you don't trust your drive, buy a new one. They're only about

[BesmirG]

I understand! Just if anyone else there is interested to see how a drive can lie, lol, I made two final tests and still the Cue-s don't match (but now in TRACK 04 AUDIO), so my drive has something to do here.

 

One is TRACK 04 AUDIO

INDEX 00 61:43:07

INDEX 01 61:44:16

 

The other is TRACK 04 AUDIO

INDEX 00 61:42:16

INDEX 01 61:44:16

 

Thank you all for the help...
