I have a MacBook Pro 13", wanted to completely reset it and discovered it wont reinstall to the original OS because OS10.7 was now on the disk. So I went into diskutil, erased the mac os partition and the damn thing disappeared. I was able to use time machine to restore, then decided to tempt fate again. This time the disk doesn't even show up in diskutil From terminal, when I do a diskutil list, it doesn't look like it should, shows 14 disks from /dev/disk0 to /dev/disk13. So my question: Is this the famous oh crap the drive just died, or did the erase corrupt the drive or did the flat ribbon cable just happen to show its face? I can post a pic of the diskutil once it boots back up, I'm thinking if the disk is just corrupted, can it be remounted after I use diskutil to delete anything not /dev/disk0 and then try diskutil list again?
