I have tried asking in Toshiba forums, manufacturer of the laptop, but I have not had any luck; therefore, I'll try seeing if anyone has any suggestions in here since the root of the issue is finding a driver that is compatible with the Intel infrastructure to see the drives during a Windows 7 installation.
I have a laptop, Toshiba Satellite U845-S406, that has a Hitachi 500 GB SSD drive and a SanDisk 32 GB SSD drive (as seen by the BIOS). From what I am reading in the Toshiba forums. The drives are in a RAID configuration and the 500GB uses the 32 GB as a swap drive. In the BIOS, it says that the system is using the Intel Rapid Start Technology. There are no options to switch the drives from IDE, SATA or RAID; therefore, I am restricted on the drive configuration.
The system was initially getting BSOD on the IASTOR.SYS while using Windows 7. It progressively got worse to where the system was not usable. I thought it might be a rootkit; therefore, I backed up what data I could and then tried to use the recovery partition on the drive. It came back with the same BSOD. Safe mode same thing. I wiped the drives of all data and partitions using GParted (Linux based). I tried to install Windows 7 but none of the RAID drivers from the Toshiba site are working. They will either show no drives or produce a BSOD on IASTOR.SYS.
My question for the Intel Community is how do I find out what Intel driver works with this system? Is there a bootable utility that will show me this? I am not sure what else to try. I have tried to install Windows 8 and Windows 10 thinking that maybe they would have more recent drivers that would be compatible but have had no luck. What puzzles me is how can I see the drives with GParted but I cannot see them with Windows installation? I have even tried to install Linux on the system but it cannot see the drives. For some reason only, GParted has something that allows it to see the drives.
