Okay, so I have 2 120GB Sandisk SSDs. I plugged one into the system, fired it up and all was fine to install windows (installed 7). The owner then asked to have a 2nd SSD added to do a raid 0. Contrary to online help forums, the machine (Lenovo 50-50 (90B6) did NOT have a RAID utility in the Bios, under SATA mode it was either Disabled, IDE, or AHCI - no RAID option.
We also had the issue that the machine was one SATA port shy for a proposed HDD backup drive (not yet installed). SO, I purchased this Raid card from Amazon (https://www.amazon.co.uk/StarTech-com-Port-SATA-Express-Controller/dp/B003GS8VA4/ref=sr_1_2?s=computers&ie=UTF8&qid=1470225806&sr=1-2&keywords=raid+card) to A. fix the shortage of ports and B. provide SATA support. It was a complete faff to get it working as the instructions provided no help or drivers but I got there in the end and got the cards raid BIOS going, set up the two SSDs in RAID 0 and fired up a windows 7 boot drive. It showed me a now 223.4GB partition named 'Disk 0 Partition 1. but says "Windows cannot be installed to disk 0 Partition 1. (show details). showing details tells me "Windows cannot be installed to this disk. This computer's hardware may not support booting to this disk. Ensure that the disk's controller is enabled in the computer's BIOS menu.
SO. back to the BIOS to check it's booting my new RAID 0 drive before windows and I now see that the BIOS isn't showing the new drive in the boot sequence, nor is it available to add to said sequence. Pulling my hair out here! any suggestions?
I've also tested each of the two SSDs in a separate machine and no issues whatsoever.
