Even IDE harddisks which were shown automatically as udma5 in kobian MB with intel 815 chipset(which I had previously), are shown as udma2. Even putting a command in /etc/rc.local as hdparm -d1 -c1 -u1 -X69 /dev/hdb hdparm -d1 -c1 -u1 -X69 /dev/hda has not helped to make them udma5. Further 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 am at loss to understand what to do to get udma 5 for my hdds back. -- L.V.Gandhi 203, Soundaryalahari Apartments, Lawsons Bay colony, Visakhapatnam, 530017 MECON, 5th Floor, RTC Complex, Visakhapatnam AP 530020 INDIA
