HL DT ST GSA H20N Wont Read DVD's

Hi, I have an HL DT ST GSA H20N which wont read any sort of DVD media at all, Reads and Burns Cd’s No problem. I’ve trawled this forum and followed the advice ie firmware, removing filters, checked DSA but I’m still getting nowhere. I stuck it in my friends machine and hey presto it worked fine!

Ive completed a full format and Im still in the same boat. Does anyone have any advice?

I would really appreciate it!

Thanks in advance! Chris

Try booting from a bootable DVD, eg, windooze install DVD.
