Hija,
further investigation on my last mail discovered that another thing is fishy; my first IDE drive works only un UDMA1 mode which is choosen by the driver. Apart from never having seen that 22MB/s mode before both the chipset and the drive are capable of more, the two drives on the second channel also run in UDMA2.
The drive is a: ATA device, with non-removable media Model Number: WDC WD400EB-00CPF0 Serial Number: WD-WCAAT63853** Firmware Revision: 06.04G06 Standards: Supported: 5 4 3 2 Likely used: 6 Configuration: Logical max current cylinders 16383 4047 heads 16 16 sectors/track 63 255 -- CHS current addressable sectors: 16511760 LBA user addressable sectors: 78165360 device size with M = 1024*1024: 38166 MBytes device size with M = 1000*1000: 40020 MBytes (40 GB) Capabilities: LBA, IORDY(can be disabled) bytes avail on r/w long: 40 Queue depth: 1 Standby timer values: spec'd by Standard, with device specific minimum R/W multiple sector transfer: Max = 16 Current = 16 Recommended acoustic management value: 128, current value: 254 DMA: mdma0 mdma1 mdma2 udma0 *udma1 udma2 udma3 udma4 udma5 Cycle time: min=120ns recommended=120ns PIO: pio0 pio1 pio2 pio3 pio4 Cycle time: no flow control=120ns IORDY flow control=120ns
and everything from the last report is the same here. /proc/ide/via says: ----------VIA BusMastering IDE Configuration---------------- Driver Version: 3.29 South Bridge: VIA vt82c586b Revision: ISA 0x47 IDE 0x6 Highest DMA rate: UDMA33 BM-DMA base: 0xe000 PCI clock: 33MHz Master Read Cycle IRDY: 1ws Master Write Cycle IRDY: 1ws BM IDE Status Register Read Retry: yes Max DRDY Pulse Width: No limit -----------------------Primary IDE-------Secondary IDE------ Read DMA FIFO flush: yes yes End Sector FIFO flush: no no Prefetch Buffer: yes yes Post Write Buffer: yes no Enabled: yes yes Simplex only: no no Cable Type: 40w 40w -------------------drive0----drive1----drive2----drive3----- Transfer Mode: UDMA DMA UDMA UDMA Address Setup: 30ns 120ns 30ns 30ns Cmd Active: 90ns 90ns 90ns 90ns Cmd Recovery: 30ns 30ns 30ns 30ns Data Active: 90ns 330ns 90ns 90ns Data Recovery: 30ns 270ns 30ns 30ns Cycle Time: 90ns 600ns 60ns 60ns Transfer Rate: 22.0MB/s 3.3MB/s 33.0MB/s 33.0MB/s
