Sequence of files written to a disc

[laserfan]

Regarding the preparation of files for burning to disc, many have warned that writing to to outside edge of a disc may be inadvisable for accurate writing/reading purposes. So advice is given to not fill discs too full for example.

 

I wonder if we know, or can determine after-the-fact, where files will be/are located physically on a disc? For example, if I burn a single-sided BD-25 with a Blu-ray movie program, is it correct to assume that the last of the STREAM folder contents, then the CERTIFICATE files, would be the files written to the outermost edge?

 

For a HDD you can use an app like Defraggler to see where files are located on a disc--as I write this I wonder if at least the Analyze function works on removeable optical media.

Look at the disc using something like IsoBuster. It'll show you the start LBA of each file.

Well, maybe it will, but my IsoBuster says "Sector View" needs the $40 license fee. Any others come to mind? How about my other question--does your program just write files sequentially by alphabetically, as they appear when dragged into the Source window?

You don't need to view the sectors, just look at the LBA address column.

Well, duh, I really have no idea how I missed this the first time-around!

 

Yes it's there as plain as the nose-on-my-face, and it's clear that files are written according to their filename, and that each LBA represents 2048 bytes as I might have expected.

 

Thanks LUK I know now what to expect when burning to disc.
