Sony DCR DVD101 Format Error
I had the same problem, but I didn't have any valueable data on the
DVD-RW (which was a Sony brand disc, go figure...). So, I backed up
all the videos on the disc, tried to format the disc to get it ready to
be able to be used again, and got the whole "Access Error" when I was
formatting the disc. I tried both the VR and Video format options, the
Video option came back with teh "Access Error" while the VR option came
back with "Format Error". I put the disc into my DVD burner in my
computer and was going to try and format it manually. But, as the disc
popped up in My Computer and I right-clicked on the disc icon, there
were no options to format the disc, which is unusual. I tried it in a
laptop that's about a year old (versus the other computer which was
about 4 years old), and as I right-clicked on the disc, an option was
entitled "Erase this CD-RW". Obviously this was not a CD-RW, but I
tried it anyways, and bam, after about half a minute, the mini DVD-RW
was formatted! After that, I put it in the Handycam DCR DVD101 drive,
formatted it using the Video setting (my preference), and now it works.
So, moral of the story is...try and format the disc manually on a DVD
burning enabled computer. If it doesn't work, try a newer computer.
But that's all I have, hope this helps!
