Having trouble w my external DVD writer

[qanda]This thread is about the NEC ND-6500A. Click here to see full specs[/qanda]Hi there,
I have a Lacie External DVD writer connecting through USB2, and my computer recognizes it as a NEC 6500A.
Just recently it started making a mild clunking sound and now it no longer reads DVDs. When I insert a DVD the drive runs for about a minute and then I get a prompt that the computer can not identify the format. Oddly though it can still read CDs.

I tried reinstalling the driver and roxio but no luck.

Any suggestions or advice?

still have problems but the extent of it has changed. I have had a chance to plug my drive into another computer and it has worked. So why can’t I get it to work on my computer? Any thoughts on how I can approach this dilemma?
Other components are working from my USB port. Only the DVD drive is not.

What model is your computer or motherboard? Desktop or laptop?
