wine users - Mar 2007 - Trying to get a cdwriter to write to loop device

I'm trying to use a shareware program called PowerISO to extract a .daa 
cd image to a raw iso9660 format so that I can view the contents.

PowerISO runs like this:
________________
[nate@blackbox ~/.wine/drive_c/Program Files/PowerISO]$ sudo wine cdburn.exe
Password:
Usage:
         cdburn <drive> -erase [image [options]]
         cdburn <drive> image [options]
Options:
         -erase            Erases the disk before burning (valid for R/W 
only)
         -sao              Writes the image out in "session at once",
or cue
                           sheet, mode (default is "track at once")
         -speed            Speed of burn, or 'max' for maximum speed
         -imagehaspostgap  Use if your image already contains a 150 
sector postgap
         The [image] must be provided unless the -erase flag is set.
         If both an image and -erase are provided, the media will be
         erased prior to burning the image to the disc.

So I'd guess it would try to burn to my /dev/hdc with a blank cd-r inserted.

[nate@blackbox ~/.wine/drive_c/Program Files/PowerISO]$ sudo wine 
C:\\Program\ Files\\PowerISO\\cdburn.exe Z:\\dev\\hdc 
Z:\\media\\usb1\\usarmy.daa
fixme:ntdll:NtFsControlFile stub! return success - Unsupported fsctl 
90018 (device=9 access=0 func=6 method=0)
Error verifying ISO image

Ok, so that didn't work (it terminated really quickly too). I wondered 
if it could burn to a file instead... I wasn't too sure about this, 
first I created a 1 Gig empty file:
dd if=/dev/zero of=usarm.iso bs=1k count=1000000
losetup /dev/loop0 usarm.iso
mkdosfs -c /dev/loop0 1000000
mount -t vfat /dev/loop0 mnt/

[nate@blackbox ~/.wine/drive_c/Program Files/PowerISO]$ sudo wine 
C:\\Program\ Files\\PowerISO\\cdburn.exe Z:\\media\\usb1\\mnt 
Z:\\media\\usb1\\usarmy.daa
Error 5 opening device \\.\Z:\media\usb1\mnt

I added a link to /dev/hdc using winecfg, then tried again (it should be 
eqivalent to Z:\\dev\\hdc, right?).

[nate@blackbox ~/.wine/drive_c/Program Files/PowerISO]$ sudo wine 
C:\\Program\ Files\\PowerISO\\cdburn.exe D: Z:\\media\\usb1\\usarmy.daa
Error 2 opening device \\.\D:

[nate@blackbox ~/.wine/drive_c/Program Files/PowerISO]$ sudo wine 
C:\\Program\ Files\\PowerISO\\cdburn.exe D:\\ Z:\\media\\usb1\\usarmy.daa
Error 3 opening device \\.\D:\

Should Z:\\dev\\hdc be any different than D:\\ - they produce different 
errors?

[nate@blackbox /media/usb1/US Army course]$ ls -al ~/.wine/dosdevices/

I also tried creating a iso9660 image to let cdburn write to. However, 
that did not work, and I found out that iso9660 is strictly read-only 
anyway.

Are there any suggestions or wisdom on what the errors mean?
Thanks,
Nathan

You cannot use a windows program to burn a CD under wine because this
requires direct hardware access.

That would depend on the program...

Why?

cdburn expects a device (a CD writer), no a filesystem.

No. Once you are inside wine, a device file looses most of its meaning.

Have you tried 'wine cdburn.exe foo.iso usarmy.daa', where foo is a file
that does not yet exist?
