I've had to replace a failed 80G IDE drive with a 150G SATA drive.
Writes to the new HD seem to be hogging memory, stalling X response
and other HD reads such as causing music playing from a .wav file on
HD to stutter.
After reinstall of Slackware 11 [1] from original media, recovery of
files from backups and tweaking all the idiosyncratic configs, I'm
back to just where I was before the failure except for this bogging
down on big HD writes.
These, which write the HD, cause the problem:
cp USB-stick/bigfile -> hda3
cp hda3/bigfile -> hda4
but these, which only read the HD, don't:
cp hda3/bigfile -> USB-stick
cp USB-stick/bigfile -> Other USB-stick
mplayer hda3/some-video.mp4
I have P4 CPU, Slack 11, 2.4.33 kernel and 256M of RAM with which this
problem didn't occur before replacing the HD.
The new SATA HD plugs into one of two ports on the IBM mobo labeled
"SATA IDE 1" and "SATA IDE 2". The drive is seen by Linux as hda,
not sda. (Some on-mobo emulation I don't know about?)
I have /sys but it's empty.
/proc/sys/vm contains the following files:
bdflush
block_dump
kswapd
laptop_mode
max-readahead
max_map_count
min-readahead
overcommit_memory
page-cluster
pagetable_cache
vm_anon_lru
vm_cache_scan_ratio
vm_gfp_debug
vm_lru_balance_ratio
vm_mapped_ratio
vm_passes
vm_vfs_scan_ratio
It seems like I should be able to fix this problem -- apparently vm
hogging RAM on HD writes -- with a tweak to one (or more) of those
files.
After looking at /usr/src/linux-2.4.33.3/Documentation/sysctl/vm.txt,
I've tried (one at a time):
Reducing max-readahead from 31 to 15
Reducing bdflush [interval] from 500 to 100
Reducing bdflush [sync] from 60 to 20
with no effect.
Any specific suggestions on fixing this?

[1] Yes, there's a reason for using Slack 11, not relevant here.
