Subject:   IDE problem?
Message-ID:  <F254FFK7dcLdZs3JcXu00006d09@hotmail.com>

Board: Intel L440GX+

I have 2 disks in my machine.  SCSI (18GB U2W 10Krpm) and a
IDE 30GB maxtor.

The maxtor is mounted on /www2.
If I do anything on /www2 it almost stops responding for other requests.
For example;  tar -cvzf domain.tgz domain.com runs smooth.
If I jump to another session and do a 'ls -la' it takes about 10 seconds
to return.  The SCSI drive does not have this issue.

I think there must be a problem because locally I have freebsd running
on IDE and it does not produce the same conditions.
