Mad dog dvd burner

Connect it to a different computer, to see if the device is working at all.

If not, and if the Mad Dog is still under warranty, then exercise the warranty to get it repaired/replaced.

Otherwise, disassemble the casing, remove the disk-drive,
and connect the disk-drive as a "slave" disk-drive in a desktop computer, to see if the disk-drive is OK. This would imply that the USB-to-disk-drive interface inside the casing is the problem.

Try connecting the USB device to a different USB port on the same computer, or to a USB port on a different computer, to confirm that the USB device itself is working correctly.

Make sure your jumper settings are correct. If it's your only drive, set it to "Master" if it's a second drive set it to "Slave"

Put a DVD disc in and it will change from CD to DVD

First do windows update until everything is fully updated, pay careful attention to any hardware update that is needed in the left column and if that does not help go double click on MY COMPUTER select the drive( D) then right click, go to PROPERTIES then RECORDING set or change your defaults.
Hope this helps.

please ceck that the DVD drive is properly connected to its port. and if the problem persist call an technician.

I don't know if I can be of any help here, but I purchased my Mad Dog Multimedia MEGASTOR DVD+/-RW burner a few years ago for my PoweSpec with XP Home Edition. I recently bought a new computer installed with Windows Vista Home Premium (which yes, I actually do love) and my external Mad Dog works perfectly, I didn't even have to update any drivers, it recognizes the drive everytime I plug it in (via USB). I don't need it anymore, but it's actually a better burner than the one that came with my system, which I bought new in March, although it's now discontinued. Do you have the disk for it? If so, have you tried running the disk again? What OS and processor do you have? In the event that it might be a matter of obtaining the proper driver for it to work for you, I also am a member of a great and extremely reliable site for free driver downloads. Free membership is limited to a few downloads within a certain period of time,and then you have to wait 24 hours, but other than that there is no limit so that's what I do. Just for the record, there was a period where my old XP was out of commission and I had to resort to my very old HP Pavillion that was about 10 years old, came with Windows 98SE(when that OS was brand new) and all I needed to do to make Win98 recognize the drive was download a driver and it worked just fine. LOL, that has a processor that runs at 600 megahertz, so you can imagine if my Mad Dog worked on systems like that, XP Home and now Vista Home Premium without a hitch, I was quite impressed with their products.

try downloading a new system at www.slysoft.com it works graet and you can burn read and rewrite with thier software you can also test drive it for 20 days to see if you like it lala linda

The firmware updates and drivers won't help you. You can try turning it off, disconnecting it from your PC, then turning off your PC, turning on the burner and then turning your PC back on and hope that it's recognized. The chances are slim as this is a known issue with Mad Dog external USB DVDRW's and you need to send it in for repair if it's under warranty or put it on eBay as broken (or throw it out) otherwise and get a new one. I have a Mad Dog external DVD-RW and ran into the same exact issue, for a while it was working on and off as long as I didn't turn the burner off while my PC was on but for a while now it's just recognized by the PC as mass storage device rather than the DVDRW that it is and when you reach that point the aforementioned two choices (repair or throwing it out\putting it on ebay) are the only ones you have.

I don't think the burner is compatable with Mac. http://www.mdmm.com/products.php?categoryid=2 Here is the site. Check your model here. I only found Windows compatable. Good Luck, Tim p.s. someone out there must have some hacked driver.
