My Lacie external (USB) DVD writer has stopped being recognized by Redhat 8. I installed this successfully last November, but in typical fashion, I totally forgot how I did it. CDRecord-ProDVD and CDrecordwrapper-sh are still present in my /usr/bin directory, but when I run "dmesg" I get no mention of the DVD writer. However in the /mnt directory, there is indeed a "dvdrw" folder, although there is also stuff in the cdrom folder even though there is no cd in the cd-rom. The fstab file shows no DVD device either. All this seems to have happened because I removed the USB plug during relocation of the computer.

I'm pretty sure there's a simple solution to get this computer to recognize the writer again, but I've had little luck with Google, or even searching through here. Please help!
