Anything I should > have jumpered that isn't? Settings on the controller that I've missed? The problems you are describing are of some other nature, trust me. I've also got this kind of problems occasionally, and last time, i've been suspicous about the drive, too. It turned out to be a weak power connector, my box is full of Y-cables... <:) Try the drive with a totally different power supply. Maybe your power supply has too many spikes on the DC (possibly even R.F. spikes, use an oscilloscope if you can). Make absolutely sure that your drive does _NOT_ supply term power to the bus. Let the controller do this, not the drive. (Normally, the only problem with this is if a controller supplies +5 V for passive termination, and a drive supplies +2.85 V for active termination, but you never know for sure. Remove the jumper if there is any.) Some drives don't like to be grounded. Try it without connecting the metallic case to ground. Finally, if the drive overheats, it usually also turns down. -- 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. ;-)
