I don't think they know what they are talking about.
An ISO image is the size of the data (+metadata), no empty sectors.
Though, you could append NULL bytes to the end of the file.
My question would be, "What changed between when it was working and now?"

Every time my company releases a new version of its software, someone
creates a ~1.5GB ISO image of it using /genisoimage -J -R -D -V
[volume_name]/, and then I use a Nexcopy USB duplicator to burn the
ISO to 2GB flash drives.
This process no longer works; it produces a "cannot get drive
geometry" error. According to gparted, it's b ecause the partition
table is bogus - these flash drives are created with a 7.34GB
partition, which obviously isn't possible on a 2GB flash
drive. Nexcopy's support insists that this is because of the way the
ISO was created even though known good ISOs from other versions
produce the same error.
I'm supposed to "Check the partition size...and then re-master the ISO
so they all match. So if you have a 1.2GB CD-ROM partition size, you
need to have a 1.2GB ISO file."
I don't know enough about the ins and outs of genisoimage or ISO files
to know if this is accurate or not or how I would do it. Any insight
would be much appreciated.
