sikoone and phil, thanks again for the help!
phil, your exactly correct. i have two hard drives, 3 directories. one of them is split into 2 drive letters (western digital), it's just they way we set it up originally. the secondary ide channel is used for my dvd drive and cd rom. the plextor drive is the master, then the cable continues down to a sony cd rom which is the slave. the dvd drive is E and the cd rom is F. at this point i've gotten all of my drives to complete a check disk. it took a while for the G drive to complete but it completed eventually. the two options for diskcheck were: Automatically fix file system errors, & Scan for and attempt recovery of bad sectors. i wasn't sure which to run so i did both of them. is it supposed to list errors if it finds anything? it basically just said disk check complete each time, no problems listed. i've also defragmented my C & D drives, it said that G didn't need defragmenting.
Phil, i'm not sure what you mean by "windows 2000 cant report the current udma mode". I've gone into bios to look for udma settings. I couldn't find any such option, do you know which category it would be listed under? I see:
Standard CMOS features
Advanced BIOS Features
Advanced Chipset Features
Also, thanks for the link to the plextor diagnostic page. i have already done this, the drive seems to be fine. Regarding the Nero upgrade, I'm not sure if I can do this becuase somebody installed it for me a long time ago, i do have the serial number but i'm not sure if it will let me upgrade. I have version 126.96.36.199. Regarding the antivirus resident protection feature, are you refferring to something inside Nero or my actual PC antivirus? Are you saying turn Norton antivirus off while burning?
Very much appreciated,
