I have mandrake linux 9.1 and ASUS A7N8X deluxe MB with nforce chipset Athlon 2400. I have two harddisks. one in hda and other in hdb. Previously I had i815 intel board. There it is shown as udma5 for both. Now I get as udma2 only.Accordingly hdparm -tT values are less. Previously I had [EMAIL PROTECTED] lvgandhi]# hdparm -tT /dev/hda /dev/hda: Timing buffer-cache reads: 128 MB in 1.42 seconds = 90.14 MB/sec Timing buffered disk reads: 64 MB in 2.30 seconds = 27.83 MB/sec [EMAIL PROTECTED] lvgandhi]# hdparm -tT /dev/hdb /dev/hdb: Timing buffer-cache reads: 128 MB in 1.42 seconds = 90.14 MB/sec Timing buffered disk reads: 64 MB in 1.59 seconds = 40.25 MB/sec Now I have [EMAIL PROTECTED] lvgandhi]# hdparm -tT /dev/hda /dev/hda: Timing buffer-cache reads: 128 MB in 0.43 seconds =297.67 MB/sec Timing buffered disk reads: 64 MB in 4.18 seconds = 15.31 MB/sec [EMAIL PROTECTED] lvgandhi]# [EMAIL PROTECTED] lvgandhi]# hdparm -tT /dev/hdb /dev/hdb: Timing buffer-cache reads: 128 MB in 0.43 seconds =297.67 MB/sec Timing buffered disk reads: 64 MB in 2.19 seconds = 29.22 MB/sec As can be seen buffered disk read has come down 30 to 50%. I have used hdparm -c1 -u1 -d1 -X 69 /dev/hda and hdparm -c1 -u1 -d1 -X 69 /dev/hdb in /etc/rc.local. Still udma status has not changed. what to do to change udma status to its true value. -- L.V.Gandhi 203, Soundaryalahari Apartments, Lawsons Bay colony, Visakhapatnam, 530017 MECON, 5th Floor, RTC Complex, Visakhapatnam AP 530020 INDIA ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ linux-india-help mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/linux-india-help
