8.04 SATA Drive clarification
Hello, I am wondering about my DMA settings. I've got a new build and want to make sure I'm getting the most out of my drives. System: AMD Athlon 64X2 6000+ Asus M3A Mobo 2 Western Digital SATA Drives 1 ASUS SATA DVD drive Ubuntu 8.04 The two Western Digital Drives seem fine Output of "sudo hdparm -i /dev/sda
Code:
/dev/sda: Model=WDC WD4000AAKS-00A7B0 , FwRev=01.03B01, SerialNo= WD-WMASY0464400 Config={ HardSect NotMFM HdSw>15uSec SpinMotCtl Fixed DTR>5Mbs FmtGapReq }RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=50 BuffType=unknown, BuffSize=16384kB, MaxMultSect=16, MultSect=?16? CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=781422768 IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120} PIO modes: pio0 pio3 pio4 DMA modes: mdma0 mdma1 mdma2 UDMA modes: udma0 udma1 udma2 udma3 udma4 udma5 *udma6 AdvancedPM=no WriteCache=enabledDrive conforms to: Unspecified: ATA/ATAPI-1,2,3,4,5,6,7 * signifies the current active mode
Seems to be running @ udma6 (Same for /dev/sdb) It's the DVD Drive I'm wondering about Output of "hdparm -i /dev/scd0"
Code:
/dev/scd0: Model=ASUS DRW-2014L1T , FwRev=1.02 , SerialNo= Config={ Fixed Removeable DTR10Mbs nonMagnetic } RawCHS=0/0/0, TrkSize=0, SectSize=0, ECCbytes=0 BuffType=unknown, BuffSize=0kB, MaxMultSect=0 (maybe): CurCHS=0/0/0, CurSects=0, LBA=yes, LBAsects=0 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 AdvancedPM=no Drive conforms to: unknown: ATA/ATAPI-3,4,5,6,7 * signifies the current active mode
Seems to only be @ udma4, is this the max I can get out of this drive. i.e. if udma6 is not listed does this mean the device isn't capable? Thanks for any ideas you might have!

That's the correct max speed. Everything appears normal

Re: 8.04 SATA Drive clarification
promet, would you please post the output to
Code:
dmesg | grep ata
hdparm -Tt /dev/sda
Also, stick a CD in the CD drive and run
Code:
hdparm -Tt /dev/scd0
