| |
I'm trying to get my hard drive to use UDMA/66. I'm thinking the cable is not being detected. When the HPT366 bios is set to UDMA 4; using hdparm -t, I get a transfer rate of 19.51 MB/s. When the HPT366 bios is set to PIO 4 the transfer rate is the same. Is this normal for a UDMA/66 drive? What makes me think something is wrong is that the log says
"ide2: BM-DMA at 0xbc00-0xbc07, BIOS settings: hde:pio" <-- PIO?
and
"hde: 27067824 sectors (13859 MB) w/371KiB Cache, CHS=26853/16/63, UDMA(33)" <--- UDMA(33)? shouldn't it be UDMA(66)?
Any ideas what might be wrong? Possible bug?
