I've just tried it, and apart from some slowdown in the floppy formatting part (an obvious sign that the driver loses floppy revolutions when reading), no errors so far. This is with both of my disks running iozone simultaneously. That's an ASUS P55T2P4 (i think it's using the SMC FDC+serial+ parallel chip) and two NRC 53c810's. I would indeed suspect the power supply, or some ground loop problem. The disk seek operations could easily cause some current jumps on the power lines. Try powering the disk drives from another supply if you can. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
