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 G 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?
