Hello all. After the release of yosemite I decided to do a clean install. This is because I was having problems removing my yosemite beta partition. After many failed attempts of formatting the drive I had managed to majorly corrupt the drive. The main partition that previously held mavericks was no long visible in disk utility. Also the drive has now been named Logical Volume Group. After freaking after reading online that this was not going to be an easy fix I ordered a new (and larger) ssd. Now my machine is up and running fine with this new drive. I have plugged the old drive in with a sata to usb cable to try repairing it. Has anyone got any ideas?
