Re: [gentoo-user] Incredibly slow disk access
If you have sata drives, and they are showing up as hdx, you have something seriously misconfigured. They should be showing as sdx. Deselect everything in ATA/ATAPI/MFM/RLL and select the relevant boxes in serial ATA. Dont forget fstab will need redoing to match. I always thought that if you select both, serial ata should take precedence, and in some cases you can access via both, but I have at least one machine that will only work as sata with all the older ata stuff deselected.

BTW, which speed can be treated as not slow? hdparm for my SATA SAMSUNG HD401LJ shows ~60MB/Sec. Is it normal? -- gentoo-user@lists.gentoo.org mailing list

[gentoo-user] Incredibly slow disk access
Hi All, I have installed gentoo on my laptop recently and I am having a huge problem with speed. The problem is the insanely slow disk access that I am getting. here is some output: manticore ~ # hdparm -tT /dev/hda /dev/hda: Timing cached reads: 5702 MB in 2.00 seconds = 2857.11 MB/sec Timing buffered disk reads:6 MB in 3.37 seconds = 1.78 MB/sec manticore ~ # /etc/init.d/hdparm start * Running hdparm on /dev/hda ... HDIO_SET_DMA failed: Operation not permitted [ ok ] * Running hdparm on /dev/hdd ... HDIO_SET_DMA failed: Operation not permitted [ ok ] I read on a forum somewhere that this could be caused by the HAL daemon so I shut that down and no luck :-( Any ideas? Thanks Wayn0 -- gentoo-user@lists.gentoo.org mailing list
Re: [gentoo-user] Incredibly slow disk access
Check the options for your chipset in the kernel - look at device drivers and ata/... devices. Looks like its just defaulted to the minimum as it hasnt seen what chipset you are using. Also consider moving to libata - seems better where I have tried it.
