The disk reappeared after a reboot, and is still there working fine (both read and write) after over 21 hours. > At boot, what does "atacontrol list" say, Before reboot: ATA channel 4: Master: no device present Slave: no device present After reboot: ATA channel 4: Master: ad8 <ST3000DM001-9YN166/CC4B> Serial ATA II Slave: no device present (It shouldn't even report a slave for the SATA ports, since SATA doesn't *have* slaves.) > and what about before and after you've tried to read from the drive? No change, even after being up over 21 hours. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
