Write Speed 16x

[Luffy]

I was burning Linux ISO to the disc. I wanted Write Speed 1x. I got 16x

I understand that the write speed is up to the drive. But 16x? Is it too fast?

ATAPI iHAS124 B AL0L

Disc ID: 97m15s17f, Ritek Co.

Can you post a log from that burn?

I understand that the write speed is up to the drive.

 

It is a combo of drive+firmware version+media.

 

 

1x is never an option for DVDs, and in fact even on CDs these days 1x just isn't available.

DVDs usually start at a minimum write speed of 2.4x, but depending on the drive/discs usually the slowest would probably be 4x.

 

I don't really know why some people still insist on such slow speeds anyhow, perhaps we really should make a sticky that includes recommended writing speeds, and also a notice saying that slowest speeds does not produce the best burns.

 

For single layered DVD+-Rs, 8x is usually fine but I don't see why 16x can't be used if you are using decent media such as Verbatim DVD+R (MCC DYE), up to date firmware on your burner, as well as most recent version of imgburn and running the latest XP or Win7 service packs.

 

Just remember to verify your burns. I see no reason why you can't burn successfully at 16x though.

16x is the slowest speed your burner supports on that media, and being it CD media, it's probably the best burn quality you can get. Besides, it verified OK, which means the disc is a good copy of your source ISO image, so you don't need to worry about it.

Does it mean that no matter what write speed is. As long as it verified OK. It's a perfect burn, right?

[Rincewind]

Correct, if you get a successful burn and verify at any supported speed it should be fine.
