Hi Michael,

If the new system has an EIDE port (some new systems from manufacturers 
like Dell for instance don't have EIDE ports anymore, only SATA), a 
physical slot to mount the disk, and a spare power connector for it, then 
it should work fine. The SATA channels are separate channels from the EIDE 
channels.
