this is really weird but it seems fine now though. I installed a USB card that I have used in the G4. I thought I would put the wireless USB stick (netgear) in the computer using the interal USB port that the card has so I can keep the exteriors one free to use with anything else I need. It work some froze and I unplug the computer. I then unplug the stick and plug it in the outside one but then the weird thing was the Hard Drive didn't show up and I spent awhile unplugging things and to get it to book in OS Tiger. I had tried the install disc which showed nothing no hard drive and somehow it finally did after more fiddling. So I ran the disk utility using the install disc to repair the disk and it showed it was un-repairable. I had to reinstalling 9 and then Tiger and update it which is now back to normal. Anybody know why the hard drive suddenly be bad and have time getting it to work again? Also anybody have weird issues or experience with their macs?
