Is this the tsize=XXXXs option? I tried using mkisofs -R as shown on the man page to get the
mkisofs ‐-R ‐-q ‐-print‐size /master/tree
but the '-q' option was not recognised -- should this be -quiet? Anyway, it again said my file is too
large and ignored it.
The size for 's' (sector?) seems to be 2048 bytes, and when I hand calculated the sector sizes
for the 7 other files I have in the directory (which were all smaller than 4GB and
so were not ignored), rounding up each file's sector size to the next integer, I got a sector
count of 745189, which is a little less than what mkisofs gives me (745364 with -R, or 745370
with -R -J). Am I missing something?
I calculated the sector size for each file by using the size from ls -l, and divide this by 2048,
and rounding it up to the next integer.
Will the written data be shown as files, even for the file that is > 4GB? I just want to save
it as data, and not as a video file that conforms to some standard...

Although I have one CD/DVD writer only, I do have another DVD reader (IDE) and a
Panasonic PD/CD-ROM dual that is a SCSI device (it can read/write PD (the predecessor to
DVD-RAM) disks, but can only play CDs)). Is there some way I can check if dev= is
needed or not?
Thanks in advance for any more help!
