Hi - I'm getting vastly different performance results on hda (master) as opposed to hdb (slave). Basically when my root partition mounts (/dev/hdb) I'm warned that DMA is off, yet hdparm -i shows udma as active. Basically /dev/hdb performance sucks ... I've bought both drives in the last few months. The motherboard is quite old (3 years .. I think).
Any suggestions would be appreciated. -- Thanks - Richard ============================= /dev/hda: Timing cached reads: 1360 MB in 2.00 seconds = 678.75 MB/sec Timing buffered disk reads: 146 MB in 3.03 seconds = 48.22 MB/sec /dev/hdb: Timing cached reads: 1376 MB in 2.00 seconds = 687.42 MB/sec Timing buffered disk reads: 10 MB in 3.51 seconds = 2.85 MB/sec /dev/hda: Model=Maxtor 6Y120P0, FwRev=YAR41BW0, SerialNo=Y36DHLVE Config={ Fixed } RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=57 BuffType=DualPortCache, BuffSize=7936kB, MaxMultSect=16, MultSect=16 CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=240121728 IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120} PIO modes: pio0 pio1 pio2 pio3 pio4 DMA modes: mdma0 mdma1 mdma2 UDMA modes: udma0 udma1 udma2 udma3 udma4 *udma5 udma6 AdvancedPM=yes: disabled (255) WriteCache=enabled Drive conforms to: (null): * signifies the current active mode /dev/hdb: Model=ST3200826A, FwRev=3.03, SerialNo=5ND0CVYX Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs RotSpdTol>.5% } RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=4 BuffType=unknown, BuffSize=8192kB, MaxMultSect=16, MultSect=16 CurCHS=65535/1/63, CurSects=4128705, LBA=yes, LBAsects=268435455 IORDY=on/off, tPIO={min:240,w/IORDY:120}, tDMA={min:120,rec:120} PIO modes: pio0 pio1 pio2 pio3 pio4 DMA modes: mdma0 mdma1 mdma2 UDMA modes: udma0 udma1 udma2 udma3 udma4 *udma5 AdvancedPM=no WriteCache=enabled Drive conforms to: device does not report version: * signifies the current active mode -- No virus found in this outgoing message.
