Configuration of HD's on KT7-R Non-Raid

Will there be a problem with this configuration? Mainly the 6.5 as slave to 20gb on IDE4.
IDE1 CD-RW master, IDE2 CD Rom master, IDE3 40gb HD master, IDE4 20bg HD master - 6.5gb HD slave.
MOBO is a Abit KT7-R not set up for a Raid array.

I had the 6.5gb and slave to the CD-RW and was told I should not have a HD slave to an
ASPI device.

Thanks
