"I have a Ricoh MP7060A burner" First of all you have not given any details of your system.
I have the same burner. I had more problems than you can think of. Usually this is because of some incompatibility between software. I have too many software installed on my system but now I dumped Easycd creator and am using latest nero, which is buggy at this stage. The ultimate burning software WinOnCd 3.8 power edition. Now I can burn without any buffer underruns.
Reinstall motherboard drivers. I found this makes the system run much much much faster. Do this after all software you want is installed. But make sure you install the latest.
Keep your system junk free. I use norton utilities and do a check every time before I shut down after a session of games and stuff. Norton utilities finds stuff which has gone wrong in the registry. Well this is what I do..
Check Aspi layers
I still am on the same firmware version of ricoh 1.50 for thid drive and still now it works like a charm. So have not thought of updating to latest firmware.
It might not be easy cd creator either. Before it used to work for me good. even now it does but it might have a compatibility problem with somthing else.
I am no expert but ask some one to check your interupts(device interupts) as you have not given any specs I cannot say. I personnaly have a lot of stuff loaded on my pc. I have this constant problem of display with any Tv tuner cards not showing me good picture even when I have a Nvidia 32MB TnT2 Riva M64 pro. I have changed several cards. My system has been reconfigured. I dont find any compatibility problems in system properties. Also my usb ports are not detected by my system. well look at me go on. Anyways if you have any questions email me coz I dont visit the forums much coz I never get any help here. I only come to help. Bye
