DVD backup for windows 7
I've been trying to backup my system (Compaq presario CQ60-215DX w/32 bit windows 7) to Sony DVD+RW discs. Each time I attempt this I'll get a couple of discs done and load another blank DVD, I steady get an error in event viewer saying that the cdrom device has a bad block? How is it that all these DVDs can have bad blocks(10 out of 20 DVDs?) is this a DVD problem or is the drive screwy-or possibly the backup program...

I suggest you check filter drivers. Step1: Delete filter driver===================== 1. Click "Start", in the Start Search box type "regedit" and press Enter. 2. Navigate to the following key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318} 3. Right click on "Class", click "Export"; please name the file as "RegBackup" (without quotation marks) and then save it to the C:\ drive as a backup. Note: In case we need to undo the modification, we can double click this RegBackup.reg file to restore the registry key. 4. Highlight this key, on the right pane, check if the "Upperfilters" and "Lowerfilters" values are present. If so, please right click on the values and select "Delete" to remove them. After deleting filter drivers, please reload the drivers. Step2: Reinstall driver===================== 1. Click "Start", in the Start Search box type "devmgmt.msc" and press "Enter". 2. Expand "DVD/CDROM Drives". 3. Right click the listed DVD/CD-ROM, and click "Uninstall". Please uninstall all devices. 4. Restart the computer. The drivers will be loaded automatically. If the issue persists, I suggest you lower the burning speed and try to back up again.Arthur Xie - MSFT
