If you don't know the location of the backup superblocks in your EXT2 or EXT3 filesystem, don't panic. Block 8193 is almost always a superblock backup.

command mounts the partition /dev/hda5 on the directory /mint as an EXT3 filesystem with the writeback journaling mode:

mount -t ext3 -o data=writeback /dev/hda5 /mint ReiserFS Mount Options

When introducing ReiserFS earlier in this chapter, we discussed the way that ReiserFS can optimize the storage requirements of files smaller than the filesystem block size and the ends of files that are not aligned to the block size by actually storing those files in the b-tree. The latter saves space overall but can add some overhead because of the need to allocate space for the b-tree and balance the tree. If you wanted to stop this from happening at a slight sacrifice of disk space (about 5 percent or 6 percent of the filesystem), you can pass the notail parameter when you mount the filesystem using -o notail:
