Hello, Upon rebooting my portable I get these settings: /dev/hda: multcount = 16 (on) IO_support = 0 (default 16-bit) unmaskirq = 0 (off) using_dma = 1 (on) keepsettings = 0 (off) readonly = 0 (off) readahead = 256 (on) geometry = 16383/255/63, sectors = 60011642880, start = 0
I then issue: hdparm -d 1 -A 1 -m 16 -u 1 -c1 -a 256 /dev/hda Which results in: /dev/hda: multcount = 16 (on) IO_support = 1 (32-bit) unmaskirq = 1 (on) using_dma = 1 (on) keepsettings = 0 (off) readonly = 0 (off) readahead = 256 (on) geometry = 16383/255/63, sectors = 60011642880, start = 0 So far so good. I need to stress test the HD to make sure performance is good. However on a P4 (3GHz) portable with 1G of ram, I never get close to using the drive. This is good news because the 2.6.11-gentoo-r6 kernel is really smoking for me, but, I need to test these HD settings to be sure they are good. Last, when I issue: hdparm -k1 /dev/hda I get: /dev/hda: setting keep_settings to 1 (on) keepsettings = 1 (on) But upon reboot, I'm back to: multcount = 16 (on) IO_support = 0 (default 16-bit) unmaskirq = 0 (off) using_dma = 1 (on) keepsettings = 0 (off) readonly = 0 (off) readahead = 256 (on) How to test the drive performance and make the HD settings permanent has eluded me. Ideas are most welcome. James -- gentoo-user@gentoo.org mailing list
