DiskSpeed disk quality error message, DW1640 external

[qanda]This thread is about the BenQ DW1640. Click here to see full specs[/qanda]Probably in the wrong forum, but hopefully someone can help.
I have a DW1640 installed in an external usb 2.0 enclosure, cross flashed to EW164B, firmware BEGB.
I put it together to use with my laptop. (Sony VGN-N365E)
It gets decent benchmarks from Nero DiskSpeed 4, and burns disks well, but when I try to do disk quality tests, and I keep getting the error message posted below. I doesn’t happen consistently in the same place, but always happens before a quality scan is complete.
When I connect this drive to my desktop, it will complete a disk quality scan without problem.
I have searched these forums,and Microsoft’s error message help site, but haven’t been successful in finding a solution to the problem.
A google search suggests a registry problem. Does this sound likely?

Either try DiscSpeed 5.
Or better yet use CD/DVDSpeed. :cool:

Hi :),
Thanks for replying.
I did try CD/DVD Speed 4.7.7.15, but it gives the same error.
I can’t find DiskSpeed 5 listed at http://www.cdspeed2000.com/.
Is it a beta available somewhere else?

BTW Just remembered that neither of these programs support Disc Quality scanning via USB. (If I remember correctly that is.)

Check your power saving settings. The number one problem with devices connected to laptops is that laptops often have power settings for things like the USB and Firewire ports that interfere with the proper operation of external devices. The idea is to save as much of the drain on your battery as possible by turning off anything when not in use, but the problem with that is that it causes all sorts of weird behavior, which of course, you don’t see when using a desktop. External devices need FULLY POWERED PORTS.

In fact, do an experiment. Plug your laptop into AC power and then COMPLETELY DISABLE the power saving settings (change the power profile to DESKTOP or whatever). I suspect the problem will go away.

Thank you for replying negritude :).
I disabled the power management as you suggested, and was able to do [U]one[/U] quality scan in it’s entirety. To be sure it wasn’t a fluke, I tried another, and the problem returned. :sad:Several more tries netted the same results.
Not sure where to go from here…maybe a bad ide cable that connects the usb adapter to the drive?
