Can someone help me here?
VT 82C597 Apollo VP3
hda: Maxtor 84000A6, ATA DISK drive
hdb: WDC WD181AA, ATA DISK drive
hda: 7825932 sectors (4007 MB) w/256KiB Cache, CHS=970/128/63, DMA
hdb: 35419104 sectors (18135 MB) w/2048KiB Cache, CHS=2204/255/63,
UDMA(33)
So why is hda faster?
DMA off:
/dev/hda:
Timing buffered disk reads: 64 MB in 10.19 seconds = 6.28 MB/sec
/dev/hdb:
Timing buffered disk reads: 64 MB in 12.60 seconds = 5.08 MB/sec
DMA on:
/dev/hda:
Timing buffered disk reads: 64 MB in 7.68 seconds = 8.33 MB/sec
/dev/hdb:
Timing buffered disk reads: hdb: timeout waiting for DMA
ide_dmaproc: chipset supported ide_dma_timeout func only: 12
hdb: irq timeout: status=0x58 { DriveReady SeekComplete DataRequest }
OK, so what is wrong here?
