Long story short I used Drive Genius 2.2 to delete a partition I'd made in Linux and expand an HFS+ partition on that drive to fill the drive. I got an error message during the expand and discovered that the partition I wanted to expand had vanished. I wasn't worried and just grabbed testdisk to find my old partition boundaries and restore them. It could do the first step perfectly. The second step caused an error telling me to use pdisk. No problem, so I've for some stupid reason got to rebuild the boundaries by hand. This didn't work for some reason. I just had split my unallocated space into two pieces. Looking around on google I found one set of instructions over and over and nothing else that wasn't to spend over $100 on software. Not having $100 and knowing the feat can be accomplished with pdisk if I just knew the right commands to give it I opted to follow the only instructions for mixing pdisk and testdisk that seemes to exist anywhere. They steadfastly refused to work. Things kept mentioing I should initialize the disk as the first step. I really didn't want to, because that sounded like A Bad Thing. Finally out of ideas, out of instructions, and lacking $100 I told pdisk to initialise the disk. This appeared to do nothing whatsoever, and didn't affect my effort to restore my partition boundaries. 3am, frustrated, having spent like 6hrs or so working on the issue, and lacking any other bright ideas I notice Drive Genius has an Initializr feature. This turned out to be them using rather outdated terminology for Format, and it did't give me an opportunity to say OOPS don't do that before it was asking me what I wanted to name my shiny, new, empty, full disk partition. Nothing has been written to the disk since. If i can recover the files, that's something at least, but it'd be infinitely better and easier if something could pull the old partition map out from under this new one Drive Genius so ... helpfully ... created. Notes about available machines 1) 1.5ghz g4 powerbook with leopard 2) 933mhz p3 dell with debian and nothing better than usb1 ports (disk is an external usb/firewire drive) I have access to use a copy of partition magic 7 and some utilities from a hiren bootcd, which a friend thought he'd recovered the old map from, but when he told it al to execute nothing happened. Disk was still a blank full disk partition created by drive genius. Please help!!
