Mmm, thats pretty close, Bill. Maybe its something I just noted the last time I tried to burn a disk under ide-scsi, but I caught it turning the write speed down to 8x from the 12x setting. It may have been doing that previously without advising me or?? The old times were usually just short of 10 minutes. -- Cheers, Gene AMD K6-III@500mhz 320M Athlon1600XP@1400mhz 512M 99.27% setiathome rank, not too shabby for a WV hillbilly Yahoo.com attornies please note, additions to this message by Gene Heskett are: Copyright 2003 by Maurice Eugene Heskett, all rights reserved. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
