Unable to burn DMG files to CDs on external USB2 disc burners?

Hello.

I am having difficulties burning 88.x MB DMG files to CDs (new CD-Rs and
an old CD-RW) onto two different external USB2 disc burner drives (both
have power AC connected: HP and LG Super brands). The new Mac Mini (no
disc slot drive)'s updated 64-bit Mac OS X 10.7.4's Disk Utilities tries
to burn and then fail right away or after a few seconds. The error says
"Unable to burn 'whatever.dmg' (The disc drive did not respond properly
and can't recover or retry." Nothing interesting in dmesg, but Disk
Utility's logs had details:
http://pastie.org/private/6tnqcnkwycr2yftp8gkzxw ...

I do see my drives' lights blink during the burns. I can quick erase the
old CD-RW fine. I can burn 538 MB from an 64-bit Windows 8 on my Acer
AM3800 PC with the same discs and external burner drives without any
problems. Also, I thought it was my USB cable extension, but it wasn't
it. I don't use any USB hubs either. DMG files are fine too. I did
notice copying from a CD to Mac Mini's local HDD was slow, but no
failures.

What could be the problem? Is USB2 too slow or something? Thank you in
advance. :(

Try burning at a lower speed.

I doubt it is the USB2 cable and the drives since I tried them on a
Windows PC without any problems. Something is screwy on Mac Mini or
something.

I did mention no hub in my original post -- "I don't use any USB hubs
either." :)

Hmm, I should try another USB port.

Aren't all burner drives supported in Mac OS X? I would assume they did.
I know they're years old. HP is very old like before 2005 or so.

How do I do that in Disk Utility? I did not see a speed option.

How are you trying to create the CD/DVD with DMG you do know to make
CD/DVD with DMG file you have to use disk Utility. Not just the Burn
feature from
the finder.

Also if you can't figure it out, get RIO's Toast and create their.

Yes, using Disk Utility's burner.

Hmm, OK. It's not free, right?

Then you didn't look very carefully. When you click the Burn icon in
Disk Utility, a sheet appears. On that sheet, at the top-right corner is
a little button with a disclosure triangle in it. Click that, and you
will see a bunch of options appear, one of which is the burn speed:

Ah indeed. I will try again later when I get to that Mac Mini at work
later. Thanks! :)

It showed me 4X and 10X for HP and CD-RW. Memorex CD-R showed three
different speeds (forgot to note them but who cares), and failed too.

I also tried full erase on that CD-RW and that got stuck (light blink
forever). Ugh.

I did find something about Disk Utility's report on this HP drive (also
on http://pastie.org/4211276 if the below text is messy):

Name : HP DVD Writer 300c

UNSUPPORTED for burn? Why? Aren't all USB external burner drives use the
same standard technology for disc burning? :(

No not free but not a Fortune either I think they do a Trial period
though go to Rio's Web site and see though.
