I have a Liteon 16x DVDRW SOHW-16735 which has began bringing up the error "A flaw exists in the Power calibration area" tonight. For the last week or 2 its been having trouble finializing disks. I'm pretty sure the drive is stuffed, but my question is that since dvds and cds use different lasers/frequencies/wavelengths (whatever!) maybe the CDRW portion will still work? Or do both technologies use the same 'power calibration area'? It seems to be able read dvds (data and video) OK.

thanks

Adrian.

This is a known problem in two regards:

1) Older versions of Nero 6 have been known to break on Service Pack 2 and do things they shouldn't.

2) Problems with the disks being used OR the burner is indeed going to die.

In more recent drives, they usually use the same laser and the firmware inside the unit works out whether its a CD or a DVD so generally in a nutshell if one half's gone chances are the other half has as well.

Try upgrading the driver and firmware for you drive, if avalible by the manufacturer.

heres a link to the driver/firmware page:
http://www.liteon.co...o?action=driver

but i noticed all it suggest for a driver is the windows default one, and there is no firmware update listed. all i can suggest is to try using different burning software

Liteon suggested I update the firmware too. I've done so but I haven't burnt a disk since. Personally I don't think it will fix the problem since it used to work fine and I hadn't changed anything. I also mentioned earlier I've tried more than 1 burning program.

Thanks guys for your advice so far. I updated the firmware as liteon suggested and have since burnt 2 dvds successfully. I don't understand how this fixed the problem when it used to work just fine the way it was but I'm not complaining, I guess.

You can close the thread now if you want. Thankyou again to all those who contributed.

That is why they release new firmware for devices. When they find out things that happen to devices over time, they make fixes for them. Updating drivers and firmware can fix many of peoples problems out there, sometimes just reinstalling a driver does the trick. If anyone knew exactly why a reinstall of the same old thing, helps things, they would be very wise.
