Ok, let me explain my situation. My iBook (12-inch 800Mhz G4, 348MB RAM, 40GB HDD, AirPort Extreme, Bluetooth, Combo Drive), has a problem with it. Very, very occasionally, my iBook's internal drive goes AWOL. This usually happens randomly, while the iBook is on, and has been left for a prolonged period of time. Mac OS X is unable to read from or write to the drive, so it freezes. The iBook cannot boot from the drive. When I put the installer disc in, it doesn't detect any hard drives installed, and the Hardware Test Disc just gives me an error when trying to scan Storage in it's tests. Anyway, the problem tends to go away if I unplug everything from my iBook remove the battery, and leave it for a few hours. Because the drive (or drive controller, something like that), is randomly malfunctioning, I don't want to install Tiger on it. Instead, I'd rather install Tiger on an external Firewire hard drive, and just copy across my files and such manually. No automated wizards or anything. I'll copy my stuff from the internal drive to the external drive with Tiger myself, once Tiger is installed. Now, I foresee the following problems with this setup (Tiger on external drive): FileVault is turned on, on my Panther installation, and I can't turn it off (It says that an error has occurred, and filevault will remain on, at around the 90% mark when I try to turn filevault off) I have heard that external Firewire drives can have problems with Mac OS X (although I head LaCie drives are ok) I can see a solution to the first problem. Instead of booting to Tiger and copying the files from the internal drive, just boot into Panther and use it to copy the files from FileVault to Tiger. Or, when I boot into Tiger and try to access my FileVault, will I be given a password prompt, where I can then just enter my password or FileVault master password to access my files? As for the second problem, is it true about there being no problems with LaCie drives, and can someone tell me some brands which don't have problems? By the way, I don't take my iBook out of the house, so having it tethered to a Firewire drive isn't a problem. Also, using a Firewire drive gives me another advantage; if I ever get a Mac mini, I will have a nice fast external drive to use with it, instead of a slow internal drive. Any tips or suggestions? Will my idea even work at all?
