RW/dvd was now working is not considered to be rewritable

Until 3 days ago, my driver wrote OK, now my win7 64-bit not see as rewritable.
I changed to the other three pilots, and the same problem appears.
The DVD can read and read but not write.

I suspect the file windows/system32/drivers/cdrom.sys is corrupt, but lacked the means to address them.

I even performed a restore without success.

Hello

Having too many CD/DVD programs can cause strange problems, especially if they're loading of parts of
themselves at the start because they will be competing for resources. This does not mean that this issue has been
caused by those, however, it's a possibility depending on which and how many you have installed.

You have disk problems as the CD/DVD is actually 4 discs in 1 case (CD & DVD burning and)
Playback of CD and DVD). So it is not unusual for parts from 1 or 2 to not work so that others do
correctly.

Burning at low speed, or by using the master could help. A CD/DVD cleaner might help.

Brand of the CD or DVD drive can also be the problem. Low quality (cheap brands) are always problematic.

CD/DVDs have a tolerance + - and your can read/write on the edge outside these discs
tolerances. They may be delivered, but it is generally more economical to replace the disk.

==========================================================

After the foregoing:

References to Vista also apply to Windows 7.

Step 1: Please do all the same underneath if you did some before as is often total
a process that solves the problem.

Try this - Panel - Device Manager - CD/DVD - double click on the device - driver tab.
Click on update drivers (this will probably do nothing) - RIGHT click ON the drive - uninstall.
RESTART this will refresh the default driver stack. Even if the reader does not appear to continue
below.

Then, work your way through these - don't forget the drive might be bad, could be a coward
cable or slight corrosion on the contacts (usually for a laptop) and other issues.

Another possibility is that the cables are loose. Remove ALL power, then make sure that the cables in both
ends. Remove and replace, do not just tight. For laptops, you can often clean power and
contacts data with a pencil eraser.

Some DVD players do not use the Windows default drivers so check with the manufacturer of system and
manufacturer of device to see if there is a firmware or drivers for your drive if necessary.

===============================

Step 2: You have disc problems as the CD/DVD is actually 4 discs in 1 case (CD & DVD
Burn and CD and DVD read). So it is not unusual for 1 or 2 operational so that other parts
do it right.

Did you follow the Troubleshooting Guide for the reader who still does not work? There are
the entries in registry that the troubleshooter does not solve and those who "might" be the cause.

Check with your Maker system and a device for the two possible firmware updates and the
correct registry entries for your car.

Here are the keys that I of course are those in question - for the subkeys of the CD/DVD drive
as there will be other subkeys in these keys. Do not forget to ask specific keys involved as well as
the parameters.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\IDE

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Hardware Profiles\0001\System\CurrentControlSet\Enum\IDE

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\ {4D36E965-E325-11CE-BFC1-08002BE10318}

You can probably find more info here and maybe even the exact registry settings for your
CD/DVD drive someone with the same model.

Use DevManView to locate the CD/DVD in the registry (be careful and do a prior Restore Point)
nothing change) - find the DevManView device and then make a right click on it free in RegEdit.

DevManView - free - an alternative to the standard Windows Device Manager, which displays
all devices and their properties in flat table, instead of the tree viewer

I hope this helps.
