A multimeter won't show noise or load spikes. That said, if the PSU is reasonably new and running well within its ratings, it shouldn't be a problem. >1. remove rl0 and run only one isp for the test. It's definitely worthwhile getting rid of rl(4) cards. Read the top of the driver source for reasons. >3. try to replace the ATA100 cables (the one with 80 wires) with an >older ones with only 40 cabels? I wouldn't recommend this. The 80-wire cables are electrically much better than the 40-wire ones. You might like to try a different cable. You should verify that the master/slave/MB sockets on the cable are plugged into the correct device. If you want to slow down the ATA bus, I suggest you do it in software. >4. ? anything else? Try disconnecting some of the disks and see if the problem goes away - this would help rule out PSU problems. --=20 Peter Jeremy Please excuse any delays as the result of my ISP's inability to implement an MTA that is either RFC2821-compliant or matches their claimed behaviour. --3r2sERxeG5twY2zu Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (FreeBSD) iEYEARECAAYFAkjdW0MACgkQ/opHv/APuIeNCQCfZeWDcess5d47M7pe5YczKQ+K NXQAn0fV0f4iOm4NtBKCDqeUCMCprMi9 =84o7 -----END PGP SIGNATURE----- --3r2sERxeG5twY2zu--
