>Would anyone have an idea what this means.
Lots of things have to fall together for a successful burn.
Depending on who actually makes the HP in question, it may be a UDMA or PIO Mode. If all else is good then it could be a PIO Mode device and it needs its own channel with no background apps.
Ideally, the media used should one recommended by the vendor or manufacturer.
The burner's firmware should be updated if there are specific problems (like yours).
The disk and writer should be on different IDE channels but if both are UDMA devices it should not matter (ATA4 command & queuing protocol). If the disk is ATA66+ then you must have an 80 conductor/40 pin cable with the coloured connectors - blue grey and black. Blue to the motherboard.
Optical devices do not do well on IDE or RAID controllers - keep them on the 1st or 2nd channel.
Update your chipset drivers, sound drivers and video drivers if the vendor's page suggests that it may fix a relevant problem.
Check BIOS updates for the mobo as well.
By the sounds of your issue, it just may well be cheap media that is too cheap Without knowing much else, I would not yet point to a slow CPU or slow disk. Use the latest version of Nero, too.
