Please Help: Nero Disk Speed, Quality Scan Capability Lost.

Hello.

I have a Lite-On DVDRW LH-20A1P drive (ATA133) (firmware KL0N)
For some reason Nero Disk Speed 4.11.4.0 now says that Disk Quality Scans are not supported by this drive, when 2 days ago, Quality Scans worked fine when this drive was in my old system.

Update: I also just tried Nero Disk Speed version 5.0.1.250 and it does the same thing.

I have just built a new system and i am now using windows vista 64bit, where as previously i was using windows xp pro 32bit, so i dont know if it is the OS difference or just Nero Disk Speed that caused the loss in Quality scan capability.

I also have another Lite-On DVDRW LH-20A1L drive (SATA)(firmware BL01), which still works with Disk quality scans.
Both these drives are the same model just one is ATA133 and the other is SATA. The ATA133 is the one that now for some reason wont do Quality Scans, while the SATA one still does.

Both drives burn and read DVD's with no issues.

Any ideas what happened for me to lose Quality Scan functionality on my LH-20A1P drive?

Hi,

since you installed these drives in a new computer, this might be a controller related problem.
Such is very likely with Intel chipset mainboards that are equipped with PATA controllers from Jmicron or Marvell.
