You mean "using _both cards_ in a windows enviroment works without
Is it possible hard-drive speed is an issue?
What's your hard-drive configuration?
If you're using PATA / EIDE, can you test with `hdparm`?
`hdparm` can be used both to set drive parameters & to test
throughput - my distro (Gentoo) has an /etc/init.d/ script which
should run at boot to ensure that drives' settings are optimised, but
you have to add it to the boot runlevel at install time. Could it be
that your distro has a similar script that is not being run?
Finally, you don't mention the frontend. Are you playing these
recordings across a network?
