I just replaced my SSD in a desktop (Asus Rampage III Formula MB). The system has the SSD (with OS) and two HDD with data. If the HDD are plugged in, about 95% time, the SSD isn't found and I get an 'Error Loading OS' message.
I've tried setting the system to use IDE and AHCI. No difference. This was occuring with the first SSD, but much more with new one. Old one was a Corsair F80 80GB. The new one a SanDisk Extreme II 240GB (it is also SATA 6GB).
Any ideas what is going on? Is there a setting I need to make, so the SSD is found reliably?
