Hey. So I recently experienced the flashing folder with a question mark on my '11 MBP. Went through the steps and was unable to recover data, or even reinstall OS on the drive. Although, my computer was able to browse the web via command r after logging into my wifi and could firewire boot another mac on the screen. So I assume that the rest is fine? I went ahead and bought an air and would like to now sell this on ebay, but do not want flack from anyone etc. Would it be acceptable to remove the hard drive and sell it this way, that way no one else may recover my data as well? I'd obviously state the original issue, but I want to ensure that the buyer could easily install a new hard drive and have no issues or complaints. Thanks!
