EBIOS read error: Media Error block [Solved] My Hackintosh desktop Mac SSD is giving me the error "EBIOS read error: Media Error block" etc. I need to get to the disk repair tools somehow. I have been backing up with Time Machine to a separate hard drive, so I ought be able to do a repair/restore operation if I can get to the right tools. I do have a Mountain Lion installer USB stick, but unfortunately, the PC (Asus P8P87LE mobo) seems to have developed an aversion to booting from any USB sticks! (I tried with a Linux USB stick too, just to be sure. The sticks both worked on another PC, so I think the sticks are okay.) The PC starts to boot from the sticks, but then hangs, gives up and starts the main PC boot loader (Linux GRUB) from one the hard drives. So, I probably need a CD/DVD based solution. I burned rboot to a CD, but when after it boots, it gives me that "EBIOS read error: Media Error block" error all over again. I guess it's trying to start or somehow interact with that broken Mac SSD? Where to go from here? My only install DVD is for Snow Leopard. The broken SSD was Mountain Lion. I'm guessing that even if I could boot the Snow Leopard disk, I wouldn't be able to use its tools to repair a Mountain Lion SSD? It sounds like I need a Mountain Lion (or maybe Mavericks?) DVD, unless I can somehow persuade my PC to boot from the USB stick. Any help on how to proceed, very welcome!!
