Just a thought. I ran "hdparm" on one of my disks connected to the BP6,
and it showed that it wasn't setup right at all.
hdparm -a 16 -A 1 -c 3 -d 1 -k 1 -K 1 -m 16 -u 1 -X 66 -W 1 /dev/hda
On the disk, and it gave back:
setting fs readahead to 16
setting 32-bit I/O support flag to 3
setting multcount to 16
setting unmaskirq to 1 (on)
setting using_dma to 1 (on)
setting keep_settings to 1 (on)
setting drive keep features to 1 (on)
setting xfermode to 66 (UltraDMA mode2)
setting drive read-lookahead to 1 (on)
setting drive write-caching to 1 (on)
multcount = 16 (on)
I/O support = 3 (32-bit w/sync)
unmaskirq = 1 (on)
using_dma = 1 (on)
keepsettings = 1 (on)
readahead = 16 (on)
Performance while swapping is greatly enhanced, and it's not crashed
(well, it crashed when I set it to -X 68 (DMA mode 4, or UDMA 66, on the
UDMA33 controller !) since!
I'd appricate any comments people have on disk settings...their effect on
speed & reliability.
