My UJ-845-C CD/DVD drive, throws out CDs and DVDs whenever I put one in, I recon this is an hardware problem, but can anyone help me?

This sounds like your dvd drive stopped working. try with different cds or dvds. If not there is a complicated way but if you are not familiar with computers don't do that. A service technician can easily solve it for you.

If its USB, DO NOT PLUG In till drivers are loaded. If its a brand new drive then it must be formatted before you will see it!!.

Try installing the drivers from Asus for your EXACT model of computer. Many of Microsoft's drivers are generic in nature and do not take advantage of the hardware installed by manufacturers because they can't always "talk" to their hardware.

Go to Asus's web site, type in your model number under the "Download Drivers" section and it will take you to a page where you can find the specific driver for your drive and hopefully get it back to seeing both CDs and DVDs.

A CDRW/DVD is a CD-burner and DVD-ROM combined unit. It is not meant to record DVDs only CDs.

It will not recognise a blank DVD as it is unable to read any file system.

Please note that the formats of DVD and CD are quite different. Whereas a DVD drive can handle both DVD and CD, a CD drive can only handle cd formats. Furthermore, a drive that reads both formats does not necessarily mean it can handle the writing aspect ok. You need a drive that is capable of writing/burning DVD. Most drives that come along with pcs can only write CDs but able to read both. So check your drive to see whether or not it can write on DVDs ok. Good luck

you currently have a CD writable drive and a DVD readable drive which means you can burn CDs and play DVDs but not burn DVDs

Did you try a DVD firmware update? Some dvds need new firmware to reconize some DVDs

Various issues can cause drives to occasionally balk at writing optical discs. These run the gamut of physical, hardware, and software troubles.

Inappropriate or dirty media may be to blame. Make sure to match the type of recordable disc to the drive, and check each disc for fingerprints or other contaminants. If a disc is dirty, wipe it with a clean, soft cloth in a straight line from the center hole outward. Try a quality optical drive cleaning disc if you suspect dust contamination on the drive’s laser lens.

Some discs don’t perform well with certain drives, even within their rated speeds. Try recording at a slower speed and then with a different brand of disc. Also, on PCs, verify that the temporary file storage area on the hard drive used by the burning software has enough free, defragmented space. Allocate at least 5GB for a DVD (9GB for a double-layer [DL] disc) and about 1GB for CD burning.

Try this, but if the problem persists, you need to replace the drive. Go to my computer>properties>hardware>device manager and look down the list for your cd/dvd drives and click the '+' sign then highlight your dvd drive and right click to delete. Restart the pc and windows will find the drive again automatically and install the drivers.
