The drives I was trying to compress from/to are both brand new 200GB Maxtor 7200RPM ATA133 drives. Maybe that has something to do with the bad controller on this series of boards. > > >> 29 ??

Would disabling that in the BIOS mess anything up in FreeBSD? With it disabled I couldn't test the streaming, but could try playing files.
