On the contrary, modern hardware has become reliable enough, and the market price sensitive enough, that manufacturers had eliminated almost all error detection in the name of reducing cost. Many motherboards no long support parity memory of any kind. Those that do tend to have full ECC detection and correction, although many of them only detect ECC failures during the power-on self test, not during normal operation. Although SCSI has always supported parity checking, the IDE disk interface prior to ATA/100 had no error detection whatsoever. And modern software is so unreliable that no one notices the hardware failures. -Larry Jones Hello, local Navy recruitment office?
