I am attempting to load CentOS-6 onto a ST31000524AS 1Tb SATA drive in a Supermicro 5015A-EHF-D525 system. The BIOS sees the drive and the CentOS install process sees and initializes it as well. However, even when I accept the default partitioning, I get an error during the drive formatting prior to installing the OS. The error message is: "Could not commit to disk /dev/sda". I get this error whether the drive is configured as IDE or AHCI in BIOS. The advanced BIOS configuration section makes reference to LBA addressing and a maximum value of 137 Gb. However, I had previously equipped this very system with a 500 GB SATA drive and had not experienced any problems. Does anyone have any idea as to what might be happening here?
