Filename Changes in CD Disk Image

[Heidi Elaine Dowding]

Hi,

We just ran into a weird issue this afternoon using Guymager on a CD-R. For some reason, within the disk image the characters of the filename changed (see attached screenshot). On the actual media these are fine, so we're confused about what's happening. We re-ran Guymager to make sure this isn't a one-off and then also tried dd. The files still work fine, but we're really curious about what's causing this. Any ideas?

Thanks,

Heidi

Heidi,

Hmm. A character encoding issue in the original media, perhaps? Others may want to chime in.

Could you run the following command in a terminal and send me the output? You'll need to replace /home/bcadmin/Desktop/testcd.iso with whatever the path to your filename is.

I've included sample output so you can see what it should look like. I'm specifically interested in the Data preparer id and notes about Joliet and Rock Ridge extensions, as a start.
