Hey everyone, I'm in the market for a firewire 400 usb 2 dual interface external HDD for backup purposes. I have several questions, hopefully someone can help me out. Sorry in advance if this post is in the wrong place, I couldn't find a more suitable forum category. Also sorry for the long newbie-style post. ------------- 1. About booting from an external HDD. Firewire only? PowerPC (openfireware) only or also on Intel (efi/bios)? Currently I have an iBook G4 1.33 MHz. If the HDD is connected to the computer at startup, holding option will allow for the choice between internal vs. external HDD boot. Right? 2. How does Tiger handle mounting external HDDs? If I was to partition the HDD, say 60 GB (my internal HDD size) for external booting and the rest for storage and media. Will Tiger mount both partitions?? I don't have too much screen space, and this would be super annoying. 3. How does openfirware and efi/bios handle sleep and power downs with an external firewire drive?? My iBook likes to sleep a lot. What would Sleep do to an external HDD? What happens to the HDD when the computer is shut down? Does this depend on controller inside the drive? 4. About booting from Mac OS X from the external drive, how would I go about doing this? Is there any free software to backup the internal drive completely to an external drive? I assume that this does not involve imaging, but instead simply copying over every file. I hear Dantz Retrospect isn't bad. But I would rather use the Disk Utilities that came with Tiger. 5. Anyone hear anything about G-Tech G-Drive external HDDs? They look nice and seem well-built. 6. About NTFS vs. FAT32 vs. HFS... I would like to increase compatibility and decrease limitations. But this is tough to do. Can Windows handle HFS? Read-only? Write and read? What about Mac OS X and NTFS? Friends or bitter enemies?
