While running newfs I keep getting ad0 WRITE timout error message. I'm writing to a ATA-66 HD with an ATA-66 cable). I tried disabling DMA and setting PIO4 but this made no difference. Interestingly, the number or WRITE timeouts before a successful write seemed to increase with each installation attempt (first 1 timeout, then 1 successful write, the next time 2:1, now about 10:1). If I wait until the newfs command has finished (about 3 hours) the installation continues as normal, then the system reboots randomly before the installation is complete. I am totally at a loss (I've noticed similar problems being discussed in various mailing lists, but most seem to be fixed by disabling DMA, and 4.1 was supposed to address these issues anyway). The HD is an 8.4GB Seagate ATA-66 HD. Thanks in advance, any suggestions would be most appreciated Jeremy To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
