My MBP apparently rebooted itself while I was sleeping (I had left it on; no sleep or hibernate or anything) and I thought this was weird so I signed in and thought I'd reboot it again for some reason... Anyway, from this point on I got up to the gray apple logo and the spinning circle but after leaving it on for about an hour it just stayed that way. I tried repairing it through single mode or whatever with fsck -fy and after that it didn't do anything still. With verbose mode it kept saying something like disk0s2 not there or whatever. I booted with the SL install DVD and when I went to reinstall, in Disk Utility there is nothing except just the DVD. Does this mean I have to buy a new hard drive? I've never had a hard drive fail on me before and I have several dozen HDDs from over 10 years ago that still run fine...this is my first Apple product I've purchased and already there is a failed hard drive when any other computer I had bought worked well for 5+ years without an issue until I upgraded to a better computer...I probably won't purchase from Apple again but before I give up is there anything I can do with this MBP to make it work? If there is nothing I can do I will probably just rip it open and try to transfer over my work files but if the hard drive is completely dead I will definitely be too upset to buy anything from Apple again.
