Supported Write Speeds With TDK CDRW ... Not

Recommended Posts

A curious thing is happening when I try to burn an ISO to TDK CDRW "4x-12x High Speed" media : although the ImgBurn "Media Details" pane (in 'Write' mode) shows supported speeds with this media are "4x, 10x", if I use 10x, then although the burn seems to complete successfully, the verify phase always fails almost immediately, with

"
Failed to Read Sector 11 - Reason: L-EC Uncorrectable Error
"

But if I use my "favourite" speed of 8x - which is *not* in the supported list - then everything is fine, and the burn and verify both complete successfully.

 

[ The ISO is a collection of Windows patches produced by the Heise "Offline Patcher" utility ]

 

I'm quite happy to continue using my working solution :) but I figured I should report the issue in case there's a bug in ImgBurn.

 

Here's the media details pane contents :

Maybe when you select 8x the drive is actually burning the CD-RW at 4x? Anyway, the latest firmware ensures best quality burns so I'd apply it if I were you. As for the description, it looks like a translation error, and from what I can tell, a bug was fixed where a pressed DVD disc was identified as DVD-R.

Maybe ... I suppose it should be possible to calculate the actual speed from how long it took for the number of sectors involved ... um.

I suppose so ... and hopefully it would be possible to downgrade the firmware version again if the new one turned out to be bad. But I'm kind of reluctant to mess with a drive that seems to be performing very well otherwise :ermm:

Well ... I've just tested that (with the 1.39 firmware still installed) by putting a pressed movie disc in the drive, and seeing what ImgBurn says the drive reports :

That looks okay though ... doesn't it ?

 

Anyway, I take your point about latest firmware usually being the best option. But what do you suppose Asus means by "Modified drive" ?

 

Thanks mmalves.

 

Just out of curiosity, does anyone know whether the supported speeds reported by a drive will vary from drive type to drive type ? In other words, do some drives manage a different set of speeds from other drives ? I've always wondered why my drive reports "4x, 10x" for these discs while TDK states "4x - 12x".

If the newer firmware had any problem it'd have been pulled a few days after release and a newer version with fix would be released. As for the wording I think it's due to bad translation, happens all the time with LG firmware releases :D

 

As for the speeds, it's down to each burner manufacturer, their test methods and firmware development team, so yes, each burner model may show different available speeds for the very same disc :)
