I am no expert in these things, but: I have never seen a bad Adaptec controller (and I used lots of them from 2940 to 39160). I _have_ seen many bad cables/terminators. I _have_ seen many bad cables/terminators that used to work without a glitch and suddenly started to become bad. The possibility that this happens is reciprocally proportional to the price you pay for them :-) I have SCSI systems that worked for years and started to spit out bus error messages when changes were commmitted to the driver. In most cases it turned out that these changes only triggered bad cable/ terminator errors or even firmware problems with the drive. Don't you have a friend who can give you a spare AHA2940 for testing? -Andre > > Francesco Casadei > -- > You can download my public key from http://digilander.libero.it/fcasadei/ > or retrieve it from a keyserver (pgpkeys.mit.edu, wwwkeys.pgp.net, ...) > > Key fingerprint is: 1671 9A23 ACB4 520A E7EE 00B0 7EC3 375F 164E B17B > -- Your mouse has moved.
