ND-6100A only burns at 3x after flashing to ND6500



Does anyone have an idea why a ND-6100A would only burn at 3x, regardless of media and speed, afer flashing with the 4.24 bitsetting by Liggy?

Here’s the order of things if that would give any clues…
Drive is setup as Primary Slave using Slim to IDE adapter
Ran the 6100 -> 6500 converter from TDB
Put in 6500W223 from TDB

Now DVD+R fails to burn and DVD-R burns only at 3X, even though nero detects 8x as an option

Flashed with Liggy 4.24 w/ bitsetting and now the drive is not recognized by the BIOS at all unless it is plugged in as primary master.
It also will no longer accept any flashing at all. Binflash says “sending firmware” and then sits there with the drive light flashing and nothing occuring until the machine is rebooted. I left it for almost 2 hrs and it didn’t finish or give any error msgs.

The drive still works and burns, but still will not burn at more than 3x



The error that DVD+R’s fail with is power calibration error.
CD-R’s show as max 24x speed, DVD-R shows max speed 3x even though it is rated as 8x.
They’re generic DVD-R’s from Fry’s. I’m going to go buy some name brand ones and see if there’s any different results.

The DVD+R’s that were giving power callibration errors were CompUSA/General Media disks. Changed to Dynex/Ricoh DVD+R’s and they now burn without that error. Although neither +R or -R will burn at 8x.

Using Nero CD/DVD Speed, it shows that it starts out at 2x and after .5gb has been burned it jumps to 4x. After 2gb has been burned it jumps to 6x and remains there for the remainder of the burn. The same results are consistant with both +R and -R discs from 3 diff manufacturers.

Does anyone have any idea if this is a result of the firmware that was installed or maybe a fault in the drive itself?


Slimline burners behave that way - they are all slower burners than their half-height (desktop) burner “bothers & sisters”.

Trying some media by using Nero CD DVD Speeds create disc feature is a good idea.
