I had one helluva hard drive crash over the weekend, only to realize I cannot find my backup dvd with pictures archived as far back as 2000. I think I am probably going to get an external hard drive this weekend, but after the crash, what's the point? It started out with photo booth not turning on the built in isight. Then I logged out and into another account to see if it was only on my main account. Only, logging in and opening finder completely halted the computer and I had to force a restart. It would not boot past the blue screen (pardon my lack of OSX knowledge, its my first iMac), but it passed the grey screen with the black apple. Restarting with the install cd in and running the disk utility, it told me that my drive had an "Invalid Sibling Link" and I could not mount it, repair it, fsck_hfs it, Disk utility wouldn't work with it and by the time I had learned about diskwarrior, I had already given up, let my emotions get the best of me and just reinstalled. If there is a lesson to be learned this weekend, I learned it.
