In the meantime, I ordered a fresh upgrade of Disk Warrior (4.4), and tried it on the Seagate yesterday. The reinstall, however, went surprisingly well. I finally ended up reinstalling the OS, after spending a bunch of time making safety copies of files. There then ensued a diversion after I attempted to boot my 2010 27" iMac (Snow Leopard) from an old version of Disk Warrior (3.0.3), which rendered the iMac incapable of booting normally (only Safe Mode would work): I attempted to copy the backup files to another drive, but it was beyond the capability of the Finder.

If a disk with a sibling link error is still mountable, I would advise backing up the accessible files and folders on the disk before attempting to repair it with that type of disk repair utility. Sometimes the repairs fail and the directory is damaged further. Sibling errors are notoriously difficult for some of the patching type of disk repair utilities to repair. As I said, a sibling link error makes some of your items inaccessible and can even prevent a disk from mounting. Either the link refers to the wrong node or it refers to an invalid node. This link is what is referred to as the sibling link.Ī sibling link error is a bad link to another node. Well nodes are not arranged in order and each node has a reference, or link, to the next node that contains the next set of ordered items. Imagine that the pages of the yellow pages are not in order and at the bottom of each page it says "Continued on page n," where n is the page that contains the next set of listings for the particular type of business that you're looking up. It's sort of like a realtime yellow pages. Unlike the yellow pages, nodes are dynamic and change as you add and delete items. Just like a yellow pages directory, the disk directory has pages except that its pages are called nodes. This is similar to a yellow pages directory being ordered by type of business and then business name. These entries are in order of enclosing folder and then item name. Each file or folder (item) on a disk has an entry in the disk's directory. Mac OS Standard (HFS) and Mac OS Extended (HFS Plus) disk directories have a very complex structure. It indicates that parts of your directory, and therefore some of your files and folders, are inaccessible. This is an error you definitely don't want.
