PROBLEM SUMMARY STATEMENT: Windows 7 believes my DVD drive will only
burn approximately 2.5 GB worth of content to a 4.7GB DVD-R. DVD Drive
is recognized for read, but only incorrectly for write operations.
I have googled a bit and found solutions to dvd drives not being
recognized and other general problems, but nothing specific to the very
strange problem I have.
I have 64 bit windows seven installed on a reasonably new hp pc (about a
year old)
This is a special pc, for work only (primarily video editing, dvd
creation). I do not keep this pc internet connected as it is too
critical to my work. I only connect as needed to update drivers and such.
Originally PC was Vista, but I upgraded to Win7. Everything worked fine
for many months (including the dvd burner).
Then, suddenly the dvd drive began to misbehave.
The problem I have is that Windows does not recognize the size of the drive.
I first noticed the problem when I was using explorer to write some
large (roughly 4GB files) mpg files to DVD for backup. Windows DVD
wizard tells me the files are too large to burn. I rebooted the PC many
times, connected to the net and tried to update the driver, but to no avail.
I found imageburn would bypass the problem with explorer and allow me to
burn DVD's with large backup files.
Unfortunately, my editing/dvd authoring software (Pinnacle 14) seems to
defer to windows to report the size of the disk. Thus I cannot render
an ISO or VOB file using Pinnacle as it now seems to accept the new size
of the DVD burner (roughly about 2.5 GB) as Windows must be reporting it
through some API function.
What this means is that I can't create an ISO file to use with ImageBurn
since Pinnacle keeps telling me my project file is too large for the DVD
burner. Installing a USB external dvd burner did nothing to alleviate
this problem.
I am doing advanced dvd authoring that requires Pinnacle or another
robust product to generate my image file. Now I need to transport my
MPG input files via USB drive to a second computer, where I can
successfully author the disk. However as this is a regular tasks I
perform, this is a real pain.
I found what appeared a solution online. Using F8 I was able to
"Disable Driver Signature Enforcement" and create a disk image ISO file.
However when I tested a disk I burned from the ISO, the chapter stops
were not recognized.
Even worse, I rebooted and tried to "Disable Driver Signature
Enforcement" again to retry, but that solution no longer functions.
Once again, the machine worked with Win7 for months. I installed no new
software. Machine was not connected to internet at the time the problem
emerged.
Has anyone heard of such a problem before? Any help or advice?
