DVD+R discs burned in Vista can't be read on Vista machine

OK, after three days I'm stumped. So here we go...

HP Pavilion dv6000 Entertainment PC
Intel Core 2 CPU T5300 @ 1.73 GHz
2 GB RAM
WIndows Vista Home Premium
DVD RW Drive: Slimtype DVD A DS8AZH ATA

Problem:

My computer will only *occasionally* recognize a DVD burned on the same
machine. Most of the DVDs are authored; a couple of them are just used
for data storage of .AVI files. Most of the time it thinks it is blank
(when I click on the device in Windows Explorer, I get the dreaded
"Prepare this blank disc" message). If I try to browse the directory
through the command prompt, it tells me the file system isn't
recognized. The DVD type is DVD+R. Commercial DVDs and CDs always read
just fine. On those joyous rare occasions when the disc is recognized,
the file system seems OK and it reads perfectly. But then I'll re-insert
it and it is once again "blank". The discs never fail to be recognized
on a Linux machine, or by my DVD player. They also load fine on a
friend's Vista OS.

Tried these "solutions" already:

- Ensured all Windows and HP updates are installed.

- Reinstalled driver software.

- Checked in the registry to ensure AutoPlay is set to '1' (this is a
proposed fix I've seen elsewhere).

- Deleted Upper and Lower Filters for the drive in the registry.

- Burned DVDs using different software: Adobe Encore, Alcohol 120%,
Corel VideoStudio, even Windows DVD Maker. No difference.

Any clues? Hints? Advice?

From you description, I'd --
Try the DVD drive in another system.
(It sounds like the drive is bad.) Cleaning may or may not help.
If not done correctly, cleaning may finish off the drive.

Thanks, Chuck. As mentioned, I've tried it in two other systems-- one
running Vista, and the other Linux. It was fine.

I've looked into the cleaning option, and given that the drive seems to
like all discs except (it seems) DVD+Rs, it seems highly unlikely it
would help. I'm thinking my next move is to burn a DVD+R on another
machine, and see if it reads it. Or to try DVD-R (I haven't, yet). After
that, I'll try cleaning.

The drive my have an issue similar to one I ran into with two Sony 820s.
Worked ok in Linux, were very erratic in XP.
Turned out that the drive was being ID'd as capable of a higher/faster mode
of data transfer than it was capable of (reliably) in XP-SP1.a. Really
strange, since Linux utilities showed that the drive (in Linux) ID'd
correctly and was behaving properly in all respects. These were brand new
drives, sold in retail stores. If the drive work in another system, the next
thing to think about (at least briefly) is what controllers are used. are
they the same? How about such things as oveclocking, buss speeds, and
(horrors) power supply capacity & voltages I have seen cases where the power
supply caused some strange problems, usually due to poor regulation. Some
of the faster video cards draw enough power to make inexpensive power
supplies marginal. I'd also try cleaning the connecting cable pins and
sockets with "golden grain"

I would suggest you should have a lens screening of DVD Drive because many times it may happen that your DVD lens would have some dust over it and it would not detect your Drive, you can also have a check this links also.

Exact same model and exact same problem. I had burned data dvd-r before at 2x speed and they are read perfectly even now. But when i burn the same company's dvds at the same speed now they are detected as 'blank'. I am using Power2Go since i had some error with nero. I think i will try burning the dvds at a little higher speed or just switch to a sony dvd-r. I am not sure if its the drive since the writing process is error free and also reading is fine as long as its not the recent discs. If anyone finds a solution please do reply.

HELP My name is Taiwo, I burned a DVD with drag and drop on vista i.e backing up data on the dvd and after reinstallation, when I inserted the DVD it shows blank but when checked with ROXIO it shows the name I used to name it, the used space and the remainig space and it indicates there's DATA present on it, How can I retrieve it?

Please help.

I am also having this problem in vista. Burnt data DVD's and once ejected they are no longer able to be read on same computer they were burnt from. Error msg notifying me the disc is blank and if I try to format - error msg claims disc is write protected. There is data on the disc's and there were no errors during the burn process and have tried both formats (live file system and Mastered).

It might be possible that the DVD writer driver not working properly or got corrupted that is why you are getting the problem reading the burn DVD. I will advise you to go re-installation of the driver for the DVD and see whether this is working for you or not. I think this will help you with the problem you are going through.
