I have backed up my Powerbook for the first time to an external Hard Drive (LACIE Big Disk Extreme 500MB) today in preparation for upgrading the OS to Tiger, however, I have a few questions that I hope someone will be able to answer. Here goes:

1. I'm using SuperDuper to backup and I selected the "Backup - all files" option (not sure if its the right one - can anyone explain the different options in Super Duper?).

2. I've divided the drive into 3 partitions. Can you alter the size of partitions, once they have been set up?

3. The drive is listed as 500MB, but when I mount it, it only shows as 467.5MB. Where is the missing 32.5MB?

4. The 80GB HD on my powerbook took 1 hr 53 minutes to backup, using firewire 800 (is this about the right amount of time it takes to do a backup?)

5. When I "get info" on the backup partition on the external Lacie drive, it shows a different amount of GB available and used, compared to the internal HD (only about 1GB) - is this right and how can I check that it has backed up absolutely everything before I erase the internal and do a full installation of Tiger?

6. After the backup finished, the drive continued to spin for over 1 hour and when I tried to unmount / eject it, it refused, saying that it was still in use - "try quitting applications and try again". I did - it didn't stop spinning, so I shut down the computer. Will this cause problems?

7. Once I erase and install Tiger, how do I move everything back onto the PB? - Is it a case of simply copying the backup partition back onto the internal HD?. Will all my applications need reinstalling (given the option I chose from SuperDuper?) and will everything be as I left it - i.e. all email messages listed in sequence, User profiles restored as they were etc?

That's everything for now!

Thanks for any help you can give me.

Yes, there are a few third party applications that will let you resize partitions. IMO, this is DANGEROUS. I don't want any app screwing with my partition map on the fly. Make sure you have an excellent back up before you try and mess with them. (iPartition is one)

Because it's not based on 1000, mathmatically. There are 1024 Bytes in a single Kilobyte, there are 1024 Kilobytes in a Megabyte. So there's no "missing space".

That is roughly what is is on mine...

As for moving files back, I just dragged and dropped my documents, pictures, movies, and apps that are just dragged from a DMG to the Apps folder. That worked very well for me.

Thanks for your help - been on holiday, hence delay in replying.

Managed to do a successful backup, upgrade to Tiger and fix a problem I was having with logging in (with Apple's telephone support).

Tiger is great!
