I bought a Nvidia MacBook shortly after they came out. About three weeks later I was using it and the OS froze, I tried to reboot and got nothing but the white screen. I could still boot from my FW drive with the install disk and bare bones OS install. I was lucky that I was headed near an Apple store and had a day off when it failed. The drive(#1) had failed and they replaced it with no hassle and I was on my way. All said and done I was only down for a day. A couple weeks later the new drive(#2) did the same thing, but this time I got the blinking folder with the questions mark upon reboot. I was once again lucky that I was near an Apple store and taking some time off and was able to get it fixed quickly. While I was at the store I expressed concern about having multiple drives fail, and pressed for them to just replace the whole machine. They assured me that it was just a fluke and sent me down the road. A couple months ago I upgraded the drive with a Crucial SSD(#4), today that drive had failed. It refuses to mount. Furthermore, if there are any drives connected when booting the computer gets to the white screen then hangs, endlessly. If I boot it with no drives and wait for the blinking fold with the question mark then I can plug in a my FW drive and it will boot just fine. I put my regular drive(#3) in and got the same booting problems, but it boots fine when in an external case after I wait for the blinking folder. This time I'm no where near an Apple store and don't know when I will be. To make matters even worse, my external iTunes drive came up with an 'invalid b-node size' error and appears to be totally hosed. I tried running DiskWarrior and it just hangs. What do I have to do to get Apple to just replace this computer? I'm fearful that it is going to kill drive #3 and I'll just be left with my external/emergency boot drive that also had my TimeMachine backups. If this machine kills that too then I'll have lost ALL my data. In one day I have lost a SSD and a 2TB disk. This is proving to be the biggest POS computer I've ever owned.
