Error message still the same : > >Cannot alloc 2177471968 bytes for inoinfo > Hm... There is still a chance that the first backup is also corrupt, being so close to the beginning of the partition. Try to find another backup: (example involving my root partition, UFS2) dd if=/dev/ad0s3a bs=32k | hd | grep '00 00 00 00 19 01 54 19 |' This yields 0000e550 00 00 00 00 00 00 00 00 00 00 00 00 19 01 54 19 |..............T.| 00010550 00 00 00 00 00 00 00 00 00 00 00 00 19 01 54 19 |..............T.| 00012550 00 00 00 00 00 00 00 00 00 00 00 00 19 01 54 19 |..............T.| 02812550 00 00 00 00 00 00 00 00 00 00 00 00 19 01 54 19 |..............T.| 07812550 00 00 00 00 00 00 00 00 00 00 00 00 19 01 54 19 |..............T.| Using the Z shell or another suitable hex-capable calculator, we get % echo $(( ( 0x02812550 - 0x550 ) / 512 )) 82064 % echo $(( ( 0x05012550 - 0x550 ) / 512 )) 163984 % echo $(( ( 0x07812550 - 0x550 ) / 512 )) 245904 for the last three lines, which may be used as the parameter to the -b option to fsck_ffs.
