https://community.solidigm.com/t5/archive/ssd-in-ahci-and-parallel-mode-problems/m-p/16767#M10301 <P>I had to reset my BIOS today and can't remember whether my 160GB SSD drive (model ssdsa2m160g2gc) was in AHCI or Parallel mode. I put it in AHCI mode and it wouldn't boot. So I changed it back to Parallel mode. It still wouldn't boot. So I began doing some research on this and discovered that if I were to change the mode, I'd have to reinstall Windows 7. My fear is that if I should have begun in Parallel mode after resetting the BIOS that I now have no way of booting into the drive without reinstalling Windows 7. If I selected the wrong mode, did it affect the hard drive as it is or should I have been able to boot normally if I made the right selection? BTW, I can boot to the Windows 7 CD and I can select repair the installation and in the Windows Explorer I can see all the files on my hard drive, but the system folder is not recognized by the boot loader. I've tried repairing the installation and that still doesn't work.</P> Thu, 19 Jan 2012 00:04:25 GMT idata 2012-01-19T00:04:25Z https://community.solidigm.com/t5/archive/ssd-in-ahci-and-parallel-mode-problems/m-p/16767#M10301 <P>I had to reset my BIOS today and can't remember whether my 160GB SSD drive (model ssdsa2m160g2gc) was in AHCI or Parallel mode.
