I have NEC 2500a in an external usb 2.0 encolsure.
I'm using TY media and when I try to burn at 2x or 4x through a usb 2.0 card adapter (I'm using a laptop) I always get 2 types of errors with Nero.
The first type is something regarding a scsi error.
The second type is that nero seems to freeze.
Both errors are during writing lead in.
I know that this has been discussed before (I've spent the last hour looking at threads) but still I haven't come to a satisfying conclusion. I have some addittional information.
I have flashed 1.07 but still no avail. I have the lastest nero (just grabbed it last night from their webpage (it is 6xxx.10))
I also have a usb 1.0 port on my laptop. I have SUCCESSFULLY burned 40 TY DVD-r with that port. In fact using usb 1.0 I have never had a coaster. I assume the drive burns at about 1x speed here since usb 1.0 can only supply that many mbps. Only when switching to my usb 2.0 card does the problem occur. Thus, usb 1.0 must not use scsi (or something to that extent) and usb 2.0 does? Also, 2 different types of usb 2.0 cards fail, but they work for doing any other task other than burning dvd-rs (reading a hd, playing a dvd at 8x).
USB 2.0 card works fine with a DVD+RW at any speed. So for +RW I have no bad burns.
So the problem seems directly related to DVD-r and scsi. Does anyone know the cause of the bad burns? I don't have any other dvd-r media to try, only TY. And no, I do not have an nForce mobo.
This forum has super bright and inquiring minds so I'm sure you guys have the answer so thanks in adavance!!
P.S. Does anyone know if burning through usb 1.0 is ok for burn quality? All my burns are playable in all players I tried after burning using usb 1.0, but I notice that the light on the burner goes on and off so maybe the laser is going on and off too much? I little worried about longevity of dics (thats why I'm using TY in the first place).
