So, wow. I've already posted multiple threads asking for help, and here I am again. First, I finally got my WD 160GB in my Macbook to replace my 60gig stock drive. Well, when I boot up, I get a question mark folder for just a few seconds, then the Apple logo, then my computer boots into OSX no problem. Why is the Question Mark folder appearing? I used SuperDuper to copy the drive, does that have anything to do with it? Do I need to do a fresh install? Secondly, the 60gig drive was put into a Macally external USB enclosure. It worked fine at first. Then, out of nowhere (It's been a day) the disk wouldn't spin up. I assumed the enclosure broke. But I put the 60gig back into my Macbook, and it didn't load up the OS. So, I booted up from disc, and tried Disk Utility. Disk Utility doesn't even see the drive. So, can I assume that the original 60 gig drive is dead? Does this have something to do with putting it in the enclosure? Or is it just coincidence? If it is dead, can I send it in to Apple by itself? I can wait a few days to get it back since I have my new drive, I just don't feel like driving an hour to the Apple store twice. Will Apple give me a hard time? I plan on ignoring the fact I replaced it, to avoid blame being put on me. All input appreciated.
