| Description | The driver detected a controller error on \Device\Tape3. |
| Event Information | According to Microsoft cause: being posted due to hardware problems with either the controller or, more likely, a device that is attached to the controller in question. The hardware problems can be associated with poor cabling, incorrect termination or transfer rate settings, lazy or slow device responses to relinquish the SCSI bus, a faulty device, or, in very rare cases, a poorly written device driver. Resolution: The following are some troubleshooting tips to help diagnose and pinpoint the problem: • Read the SCSI controller manufacturers technical manual to determine the termination requirements. Many modern SCSI controllers require active terminators (at least one of the devices on the bus must provide termination power). Proper termination involves both a terminator (resistor) and a device that supplies a signal to the bus for termination power. The SCSI-2 standard specifies that a controller (initiator) must supply termination power. Therefore, any controller that claims to be SCSI-2 compatible probably does supply termination power, but you should check if you are unsure. Also, many devices, especially drives, give you the option of providing termination power; if you have a jumper on the drive that reads Trmpwr, you should enable this jumper. • If both internal and external SCSI devices are attached, make sure the last device on each SCSI chain is terminated, and that intermediary devices are not. • If only a single SCSI chain is used (either all internal or external), ensure the last device of the SCSI chain is terminated and the SCSI controller itself is terminated. This is usually a BIOS setting. • Check for loose or poor quality SCSI cabling. When you have a long chain of cables with mixed internal and external cabling, you run the risk of degrading the signal. Even though the SCSI specification may specify a long distance, the specification assumes cabling that allows no leakage or interference, and the re |
