To explain sibling links, first you need to
understand that most directory
information on Macintosh disks is stored
in data structures that are technically
known as B*-trees. Examples of B*-trees
on a Macintosh disk include the Catalog
File, the Extents Overflow File, the
Desktop Database, the Users & Groups
File, and several others.
Each tree has a number of data records;
for example, each record within the
Catalog tree describes one file or one
folder. The records are sorted and
indexed for fast searching. But for
efficiency, the records are also grouped
into fixed-length blocks called nodes;
because these nodes can be physically
scattered around the B*-tree file, they
need pointers to indicate their logical
ordering. So a given node has a "forward
link", which points to the node containing
records that are logically immediately
after the records in the current node;
likewise, a node has a "backward link",
pointing to the node containing logically
preceding records.
If these linkages are pointing to the wrong
place, some files or folders might be
inaccessible. Or the OS could even hang
up trying to find some. This makes the
link invalid.
In any case, Norton Disk Doctor reports
forward link and backward link problems
separately, whereas Disk First Aid just
refers to them collectively as sibling links.
Try DiskWarrior to build a new directory.
May fix the problem without having to
initialize the disk
Dit vond ik zo snel ff op Google. Ik moet nu met een lekkere chick uit eten, dus ik kan je vanavond niet verder helpen. En morgen hopelijk ook niet.
