Re: Cables: USB 3 - Firewire800
As others have noted Merv.not worth it. I fail to see the value in it even if it were technically possible. If it were a legacy device that you just had to have, maybe...but an external Hard Drive? Nup. Just plug it into your USB port on your iMac and it will work OK, just not as fast as Firewire800. Alternatively, get an external Firewire 800 case and transfer the drive (assuming it's not a chipped drive).

Re: Cables: USB 3 - Firewire800
Thank you everyone for your responses. A dealer I spoke to suggested such a cable existed but they didn't have one in stock. However, having read all your responses I decided that if indeed it did exist there was the potential for unpleasant outcomes. I have just returned from a shopping trip with a 2TB WD My Book Studio with Firewire 800 - which raises another question, so I will start a new thread.

Re: Partitioning and bootable backup
Hi Merv, Just adding to Carlo’s reply. In order to boot from an Intel based or PPC based Mac, you may need to change the partition map. The bootable partition Map for PPC is (APM) Apple Partition Map which is Apples default. The Intel based Macs require (GUID) “GUID Partition Table to be bootable.

Re: ipad sim in europe
I am currently in the UK with my iPad. If unable to make use of free WiFi or relatives' wireless systems. I purchase time from BTFon. Easy to arrange on line with credit card.There are various options but I find the £15 for five days unlimited use works well for me and also used the same system a couple of years ago. I see the cost as well worth while to keep me sane. After a bad experience last year with a French IPad SIM I would not go down that path again. I have two weeks coming up in France but deliberately chose accommodation (apartment) that includes unlimited broadband access. In my experience, most French hotels also offer free WiFi.

Even though you will not be using Time Machine to backup to this drive as Time Machine is NOT bootable. After you format and Partition your External Drive you will use Carbon Copy Cloner or SuperDuper to create bootable backups.
