Interpreting scan

I am kinda lost here, new type scans and all. Suspect dma/ide
problems.

did you choose to burn 6x ?
the yellow one is your burn speed. imgburn is sampling the burn speed at a much faster rate than in the last version
the green one is the rpm's

Chewy 14 Dec 2005 08:34 PM

it's not my scan, what can you tell me?
it shows 16x burn speed!
I'll post another clue, I am just getting a second opinion
on my analysis of a computer with issues.
I don't know beans about these scans.

chewy partial red green colorblind, see blue hopping marsupials very well tho!

another from same drive
note cpu use!

i take it the firmware is up to date.
does it do the same on all of these discs?
on my plextor if it can sense the errors will be too big , it drops the burn speed, i dont know if an NEC can do that, mine certainly doesnt

cornholio7 14 Dec 2005 08:46 PM

what was happening to the buffers during the burn?

Chewy 14 Dec 2005 08:50 PM

up and down badly(I forgot that was clue 3?)
the firmware is dee's latest, the guy thinks that's the problem!

it's doing it consistently on a lot of disks

Chewy 14 Dec 2005 08:51 PM

I have a nf2 setup with issues that has the same problem.
erratic buffers and extended burn times

cornholio7 14 Dec 2005 08:54 PM

dma i would think
buffers hopping up and down indicate dma probs
it looks like at the start of the burn it has tried several times to go quicker but dropped again and then settled for 6x
btw the biggest difference between the nero scan and the one made using imgburn is, the imgburn one is a graph of the actual burn speed taken directly during the burn and the nero one is a graph of the read speed

cornholio7 14 Dec 2005 08:55 PM

are you using the windows ide controllers or the nf2 ones?

blutach 14 Dec 2005 08:58 PM

Buffer issues could also mean excessive use of PC during burn - especially HD. But mainly DMA.

been there done that, roundtuit new powersupply for overclocked
mobile amd
too too too many computers

Chewy 14 Dec 2005 09:01 PM

dma issues 3 firmware 0
his vote don't count, he's the patient, thanks guys, it's been informative
I'll be back as patient next! Be kind!

Try to ask to Dee if she know what can be the issue

Chewy 15 Dec 2005 07:55 AM

Dee isn't touching it, it's in her thread, especially after I blasted the FAQ's
for saying switch the cables, had to get out before I started tearing arms out.
