Hi. I bought a rev C. 1.33 12 inch powerbook about a month ago. It's my first mac. I've been very happy with it until recently. Last night the computer started to disconnect from my wireless every couple minutes, then it started throwing beachballs everywhere. After this, I was patient enough to put applejack on the computer and did the reboot. While repairing the disk it said something like "Iomega (or Iowaga) not found or failure." After this it wasn't able to anything and I restarted it and it wouldn't go past a grey screen with the apple logo on it. I'm really worried now and have no idea what to do because it just stays in that screen. Can someone please tell me what to do? Any appropriate keys I should press or anything? This is my first foray into apple and not really a good experience!
