The system is FreeBSD5.1 Release with a Seagate ATA Baracuda V 120G HDD. (Of course, the Xp boots up with no problem.) The / was mounted read-only. When I try to boot I get: /dev/ad0s2a: FILESYSTEM CLEAN; SKIPPING CHECKS /dev/ad0s2a: clean, 89827 free (715 frags, 11139 blocks, 0.6% fragmentation) Cannot find file system superblock /dev/ad0s2e: CAN'T CHECK FILE SYSTEM. /dev/ad0s2e: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY. /dev/ad0s2e: CANNOT SEEK BLK: -1 /dev/ad0s2e: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
