    this has happened three times since upgrading to Yosemite. My computer will periodically refuse to boot up either regularly or in safe mode. I can only boot in recovery. Run disk utility and says that code 8 keeps from repair, problem with Yosemite. I'm then forced to take the mac to the store to get it wiped and Yosemite reinstalled.

    What is going on and can I fix it without wipe?

    This sounds more like you have a failing drive than a problem with Yosemite.

    The last three checkups via the Mac Genius Bar say that my drive is 100%. They just wipe my computer and reinstall Yosemite and it works again. This didn't happen until I installed Mavericks.

    There is nothing about Mavericks or Yosemite that would just spontaneously corrupt a drive like that. Often impending drive failures like this are not picked up by scan tools. The only real definitive test would be to get a USB external drive and clone to that and run for a a while. If that works fine, that tells you it is your internal drive, or less likely the drive cable.

    You might try the Apple Hardware Test to see if that turns up anything.

    It's not just a problem that I'm having, many others are reporting it as well. Apple hardware test turns up nothing wrong. Mac store geniuses turn up nothing wrong with the drive. It didn't happen in Lion, it happened the second I installed Mavericks and continued with Yosemite. That's a problem with the os. I just want to not have to wipe my data because of this notoriously shoddy update.

    OP:

    I would suggest you create some kind of bootable external device that you can use.
    It could be either an external hard drive, or perhaps a USB flash drive (of sufficient size)

    If you have an external bootable source, you can attempt to boot of your Mac that way, and then run Disk Utility to repair the INTERNAL drive.
