H55N won't burn over 12x

I’ve got an H55N that won’t burn over 12x.

It reads the media code as max 12x burn, but my NEC reads it as 16x.

I’ve tried uninstalling, flashing to the latest firmware, flashing to the original firmware and nothing.

I’ve tried 2 different brands of disc, too.

I use Windows XP SP2.

Anyone have an idea of how to fix?

Might be that the firmware just doesn’t support that media at over 12x if the media’s not too good. My LG E10N does the same with RICOHJPN R03 - max speed it’ll offer me, whatever program, is 12x.

What is the media code of the discs?


please tell us the media IDs of these discs. You may use Nero CD/DVD speed (Disc Info tab) to get the required information.

Indeed there might be some media that are only supported at lower speeds than printed on the disc. This is not an issue, there might be some reason for speed limits like this.

You should try well-known quality media like Verbatim.

Hehe, Michael :smiley:

Hmmm, CMC MAG M01 isn’t terrific at high speeds, so I can see why LG would have limited the speed. I’m lucky if I get a decent burn at 8x with those. :wink:

My NEC burns them just fine at 16x.

There’s no reason why decent media labeled at 16x can’t be burned at 16x.

I’m sending it back and avoiding LG garbage from now on.

I wouldn’t exactly call it decent media (search the Blank Media forum for “CMC MAG M01” if you’re interested ;)). The DVD-R, on the other hand (CMC MAG. AM3) is perfectly decent IMO. :slight_smile:


My NEC burns it just fine at 16x, therefore it’s decent.

OMG…I should have said my NEC burns my older CMC +r’s just fine.

This new TDK branded CMC MAG M01 is a complete disaster.

Older CMC +Rs (CMC MAG E01) are great discs. :iagree:

LOL. Comedy gold.

Fits right in with other famous last words.

“I am not a crook.”

“Read my lips. No new taxes.”

“I don’t think that iceberg is a danger, Captain.”
