IDE ATA/ATA Controlers : Delete everything in there !
Hold on a second !
what if one of the hard drives are attched to the Primary IDE/ATA controller? Then how are you going to boot up. Even the PnP requires some OS to initialise or run first befor the IDE ports gets re-recognised again.
If the hard drive was connected to the extra DMA cotroller or a Raid controller the this suggestion would be right on, is that the case here ?
There was no mention as to what is the OS used in here, but judging by the nature of the problem encountered I would assume that the OS in question is Win XP. As it is the OS that has a tendency to change the IDE transfer mode from UDMA to PIO if it believes that it sees a problem with the IDE controller some how.
This has been extremely annoying and very difficult to deal with at times which make relying on the native Win XP drivers a nightmare at times.
As if you do not have the HDDs installed in an Auxillary DMA port i.e. Raid controller ( NOT Raided) there would be no way to rectify this annoying problem with out the format. As you can not just unistall the primary IDE controller and hope for it to come back.
If the HDD is attached to the Primary IDE controller like most systems do then it would be very difficult if not impossible to uninstall the IDE controller in DM and hope for it to be found by PnP upon boot up as it would NOT BOOT.
The only way that you could stop this from happening in the future is to make sure that you install the latest chipset drivers relevant to your mother board chipset. i.e. Intel or VIA or SIS . . .
If you are running the Intel chipset then their so called Application Accelerator which is the same as the IDE driver specific for intel can be very handy as it would lock the IDE transfer mode to what they are and stops the OS fiddiling around with them.
This is similar if you have a VIA chipset board, (Futureproof’s favorite chipset . . . ) as the latest 4in1 drivers would do exactly the same task.
Last but not least, updating your ASPI drivers would give your system a good over all recognition of the CD/CDRW peripherals.
As for Clone writing slower than Nero it realy depends what you are burning and what settings you are using in Clone.
Replacing the 40 Pin IDE cables that normally comes with the burner to the UDMA 80 Pin cables could also be helpful as well.
