I'm back! Unfortunately so did the problem.
Yesterday I had to perform a "hard shutdown." I only had Safari open with a few tabs and was using Finder when the famous colorful beach ball reappeared for almost an hour before the force shutdown.
Disk Utility tells me that the HDD cannot be repair. I popped in the app CD and did an extended hardware test. The result confirmed that there is an issue with the drive.
The nearest Apple store is over an hour drive so they are sending a prepaid shipping box for me.
I have two questions. I have a PC desktop and would like to perform the "Target Disk Mode" to extract personal data before shipping it to Apple. I could enter the mode just fine but it requires a fire wire connection which my PC does not have. First question, is there an alternative connection?
Second question, should I remove the Zagg Invisible Shield before shipping it? I don't want them to assume that it was the cause of malfunction and void the warranty.
