Because my Vertex Plus SSD got corrupted I reinstalled Win 7 X64. After that I see all old content on the drive still there including FSX. Why? But I can't run FSX. I suppose I have to manually remove all old content and reinstall it?!

If you want to get rid of all the old Win7 and all other content you (normally with a hdd) need to format the drive first. This option is included in the install process, and it's the same with an SSD.First - always unplug all other drives except the new SSD. Make sure the BIOS is set for AHCI mode with the SSD as the initial boot device. Second - only quick format should ever be used on an SSD drive - never a full format. Full format will write to every LBA on the SSD, rendering the SSD fully used. Quick format only deletes and then re-creates the MBR.During the install process, go to Advanced Settings and delete the existing partition on the drive, then create a new one. This will align the drive correctly, then format the drive and install the operating system.
