MD5 file created for only one of my disk copies

[jbernardis]

I just read in all of my DVD Home Movies. I got an ISO file for all of them, and an MD5 file for only one of them. Why did I receive only 1 MD5 file? Do I need this? Is there some way to generrate the missing MD5 files?

 

It WAS the smallest of the disk image files - maybe size has something to do with it?

 

Thanks in advance.

you only really need the MD5 file when its a file larger than 4.35GB ( dual layer media)

this is because the MD5 will contain the info for the layer break.

 

Its not vital, because if your files to big for a DV5 disc, and there isnt a suitable layer break , ImgBurn will tell you or suggest what to do about it anyway

 

curiosity, how large was your "smallest" file that gave you an MD5 ?

do you mean MD5 as in checksum or MDS

The image file that gave me an MD5 was only 653MB. All of my other images were at least 2.2GB tho none was bigger that 4.5GB.

 

 

And yes - I mean MD5 and not MDS.

'Create MDS File - Auto' will cause ImgBurn to make the MDS (You DO mean MDS and not MD5) if the image is DL sized OR under 1GB in size.

Actually I checked - it IS MDS - I just glanced at it before and assumed it was MD5.

 

Now I know WHY it's there - but the other questions remain - what is it for and why do I need it?

Well for small images (

 

For big images (> 4.37GB - or rather just an double layer one!), it's used to store the info about the disc structure so far the layer break position is concerned.

 

So basically, if you've no intention of mounting your little CD sized image in DT and wanting it to look like a DVD, you can delete that MDS.

 

I don't recommend deleting ones that go with double layer images though.

Well for small images (< 1GB in size), it's used so you can mount them in DAEMON Tools and it'll look like it's a DVD image - otherwise DT would emulate a CD drive/CDROM.

That answers all of my questions - thanks for the quick replies
