Hi, I have run into a problem when upgrading my current machine to use an SSD as the main boot device. I restored a backup of my original Sata drive on to the SSD and I am able to boot from it ok. My problem is that when I connect the original Sata HD to the machine it appears in the BIOS but not under windows. I have 2 partitions on the original Sata HD and had expected them to appear as partitions D and E in the new setup. However if I make the original Sata HD the first boot disk then the SSD appears as partition E under windows. My configuration is MB - Gigabyte P31-E53G CPU - Intel Core 2 Duo E7400 with 4 Gb Ram SSD - Samsung SSD 830 128 Gb Sata HD - Western Digital Caviar Black 1Tb OS - Windows 7 64 Bit with all updates applied. The motherboard has 4 Sata connectors and in the BIOS these appear as Ch 0 Master/Slave and Ch 1 Master/Slave. I have tried connecting the Sata HD as the Master on Ch 0 and on Ch 1 with the SSD the Master on Ch 1 when the Sata was on Ch 0 and vice versa. However no matter which way round I try the Sata HD never appears under windows if I boot from the SSD. My question therefore is what else can I try to get the two partitions on the Sata HD to appear when I boot from the SSD? Thanks in advance M.
