Trouble repairing Hard Disk over Firewire

I'm trying to repair the Hard Disk directory of one iBook with another iBook connected by Firewire using Disk Warrior but the iBook running Disk Warrior soon shows the spinning pizza of death and after half an hour I just get fed up and quit it.

The other iBook 'is' in Firewire mode.

Am I just being impatient or am I missing something?

Tried it again, just trying to open the Hard Disk on Firewire starts the pizza going too!!!!

DiskWarrior cannot attempt repairs if the Apple partitions of the target drive are not intact. Remember that DW is a directory utility and not a disk utility. The only intervention in a drive's logical structures that it ever makes is to repair the boot blocks after it has repaired and replaced the file directory. It is also not partial to SCSI, FireWire or USB connection problems.

You may have more success in your operation, which reads as if it were a rescue operation rather than just prudent housekeeping, if you archive the target drive's contents, reformat the drive, restore the data, and only then use DW to polish the doorknobs and dust the shelves. Normally you would just use DW directly on what is at the moment your target volume.

Not "rescue" a real nail biter, in which a lot of data looked doomed!!!!!!!!!!!

I did save it, BUT, and this is important, YOU MUST FIRST CHECK AND (if required) ENABLE THE PERMISSIONS OF THE HARD DISK ON FIREWIRE (via Get Info) TO GAIN ACCESS TO IT.

I spent a few hours watching the spinning pizza of death before I realized this, as there were no messages warning me about my lack permissions.

As you say, DW couldn't fix all the errors, so I just copied the 5GB of data to the host iBook, re-installed the System on the other and then copied it back.

Yes, Firewire saved my bacon!

Welcome to the ranks of those who have been presented with a tick in a checkbox that they did not choose to make. As you found, it can take up to two hours to restore permissions to a drive that has surreptitiously grown an 'Ignore ownership on this volume' checkmark. It is the default state of external drives, which a target disk in TDM becomes. It can happen during restores from disk images, too, as I found when I used SuperDuper!, so be on your guard. Good that you found your problem and its solution, and that you triumphed.
