 |
|
Hi, I've got a probably silly question about IDE harddrive setup. The relevant section of dmesg is as follows: | Code: | cjubon@mazeltov ~ $ dmesg | grep UDMA --
VP_IDE: VIA vt82c686b (rev 40) IDE UDMA100 controller on pci0000:00:07.1
hda: 234493056 sectors (120060 MB) w/2048KiB Cache, CHS=16383/255/63, UDMA(100)
hdc: 390721968 sectors (200049 MB) w/8192KiB Cache, CHS=24321/255/63, UDMA(33)
hdd: ATAPI 48X DVD-ROM DVD-R-RAM CD-R/RW drive, 2048kB Cache, UDMA(33) |
Now I'm wondering why I cannot get UDMA(100) for the second harddrive (hdc), too. Is this a limitation of the mobo - a dual P3 GIGABYTE GA-6VTXD - or do I have something to tweak in my configuration / boot parameters, etc.?
Thanks for your advice. |

Try using a 80-wire cable. That will allow for UDMA 66 and higher. Connect hdc as master, but that still might not work because your hdd does not allow faster speeds than UDMA 33 and you are sharing that connection..
good luck! |

You won't be able to get anything higher than UDMA 33 in that configuration. It will limit the speed to the slowest device on the channel.
The only way to get full speed would be to put the CDROM/DVD on it's own channel, or get an add-in card if you must have the hard drives on separate channels. |
