I also bought some of these Verbatim 32x CD-RWs, but the
700 MB version. Unfortunately I have the same problem
as you have described.
Once I write some files on the disc it is filled. But when I eject
and load it again, there is suddenly nothing on it.
One thing is different with my cd-rws.
When I write files they can't be read anymore.
I mean, there are for example more than 500 C2 errors
per second and the drive spins down to 1x.
I used following firmwares: QS09, QS0B, QS0C and QS0E,
but nothing has improved. The C2 errors still remain.
As I have two LiteON 52327S drives I tried both drives
with the Verbatim 32x CD-RWs.
To my surprise, in one drive the cd-rw could be written at 32x
and there were only 2 C2 errors max. When I load the disc
again the data is still there.
The other drive I changed against a new one but the problem
did not change. I guess it has something to do with the media
but also something with the drives. My drives have both QS0B
firmwares, but one drive is manufactured in September 2003,
the other one in October 2003. The September 2003 version
works with the Verbatim media.
But it can also be a software-related problem, because I changed
the "damaged" drive, although it was not damaged at all.
I also changed my power supply, my mainboard and my hard-drive
but it has seemingly nothing improved at all.
(It has "only" improved the computer's performance )
Are you able to read the data you write onto the disc?
I think that the media is bad. I have 5 discs but all do not
work with one drive. Nevertheless I still prefer using 4x CD-RWs
because it is more secure when you need reliable cd-rws.
