Backup Crashes

[Tanny]

Hi all,

First, thanks for SuperDuper. It's a miracle compared to what I've been doing for years.

I seem to have a problem when first setting up a backup drive, that is, when I'm transferring all the data on a drive over for the first time.

An example from yesterday.

I was backing up a drive on an old G4 Tower to an external Firewire drive. (tech details below)

The machine froze up about half way through, and I had to pull the power plug. I tried again, crashed again.

This so corrupted the drive I was trying to back up that Disk Utility couldn't repair it, and I had to toss that drive.

I've seen this crashing problem before, during the first backup. Once I'm past the first backup, and am doing smaller incremental backups, all is well. In other words, it looks like SuperDuper or the drives choke on too much data, or something.

I've got a new drive ready to back up. I've manually installed the OS on the backup, and copied all the files over to the backup drive, no problem.

I now want to SuperDuper, so it will be good startup drive. I thought I should check in here first.

Advice? Why the crashes, do you know?

Thanks for any replies!
