Create an image of /dev/sdb called sdb.img
dd if=/dev/sdb of=sdb.img
Mount the dd disk image
Establish sector size. Establish where the partition starts
fdisk -l sdb.img
Calculate the offset
startsector*sectorsize 63*512=32256
Mount the disk image
losetup --offset 32256 /dev/loop0 sdb.img
Fix the partition in the disk image Use the appropriate version of fsck and switches
e.g. fsck.reiserfs --fix-fixable /dev/loop0
Mount the partition in the disk image (optional)
mount /dev/loop0 /mnt/image
Also possible as
mount -oloop,offset=32256 sdb.img /mnt/image
Restore the disk image to a new physical drive (ensure it is unused and not mounted) Unmount the partition, if mounted
umount /mnt
Unmount the disk image
losetup -d /dev/loop0
Restore the fsck'd disk image
dd if=sdb.img of=/dev/sdb
