The installation in the notebook ran as expected unspectacular, unfortunately, the SSD does not use in AHCI mode in combination with Windows 7, it is no longer recognized simply after the changeover. This result does not change, despite all attempts, such as AHCI driver only Windows, AMD drivers, different settings in the BIOS (legacy, UEFI, both) before or after reinstallation etc.. So far, therefore, makes the E145 with the Crucial SSD BX100 operate only in Compatibility Mode, first use again with the traditional hard drive.
