Hello After a crash, when I try to mount the (USB-connected) disk, I get this error:
# fsck /dev/da0 ** /dev/da0 Cannot find file system superblock ioctl (GCINFO): Inappropriate ioctl for device fsck_ufs: /dev/da0: can't read disk label So I did a newfs -N to see the superblocks. I really don't want to lose the data on here if I can help it: # newfs -N /dev/da0 /dev/da0: 239372.4MB (490234752 sectors) block size 16384, fragment size 2048 using 1303 cylinder groups of 183.77MB, 11761 blks, 23552 inodes. super-block backups (for fsck -b #) at: 160, 376512, 752864, 1129216, 1505568, 1881920, 2258272, 2634624, 3010976, 3387328, 3763680, 4140032, 4516384, 4892736, 5269088, 5645440, 6021792, 6398144, 6774496, 7150848, 7527200, 7903552, 8279904, 8656256, 9032608, 9408960, 9785312, 10161664, 10538016, 10914368, 11290720, 11667072, 12043424, 12419776, 12796128, 13172480, 13548832, 13925184, 14301536, 14677888, 15054240, 15430592, 15806944, 16183296, 16559648, 16936000, 17312352, 17688704, 18065056, 18441408, 18817760, 19194112, 19570464, 19946816, 20323168, [loads more] I know that fsck doesn't see -b, so, using fsck_ufs: fsck_ufs -b 160 /dev/da0 Alternate super block location: 160 ** /dev/da0 160 is not a file system superblock # fsck_ufs -b 376512 /dev/da0 Alternate super block location: 376512 ** /dev/da0 376512 is not a file system superblock # fsck_ufs -b 752864 /dev/da0 Alternate super block location: 752864 ** /dev/da0 752864 is not a file system superblock # fsck_ufs -b 1129216 /dev/da0 Alternate super block location: 1129216 ** /dev/da0 1129216 is not a file system superblock # fsck_ufs -b 1505568 /dev/da0 Alternate super block location: 1505568 ** /dev/da0 1505568 is not a file system superblock # fsck_ufs -b 1881920 /dev/da0 Alternate super block location: 1881920 ** /dev/da0 1881920 is not a file system superblock ...so 3 questions really: 1. is there a way to tell which ones are really superblock backups? There are thousands. 2. if they're not superblock backups, then why does newfs -N say they are? 3. is the disk just hosed? thanks -- John _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
