NEC 2150a burning problems

When I try burning a project (an assortment of backup folders) onto DVD, the burn fails at 75%. I don't have any memory-intensive programs running - I'm using Nero to burn. Ideas what could be wrong or what I should check? Should I RMA the drive with newegg?

Thanks.

Whoops, the title was supposed to be '2510a'. Anyways, seems that one of the files must be fucking it up. I've burnt 6 discs now, each stopping at 75%, which would explain why it stops at the exact point each time. I tried burning other files and it went fine :/ Has anybody experienced this before? Any way to check/fix the corrupt file? It so happens the file is in an important folder of backup materials, but I have no way of finding out which one it is to rectify the situation.

haven't experienced it at all and i to have the 2510a. sure it isnt your media?

Nero did that to me with a CD-Rom burner always failing at 75% and I just switched to using Alcohol to burn out of lazyness, I ended up formatting a while ago and when I reinstalled Nero it worked fine.
