Make sure the file system being used is optimized for an SSD. Because SSDs store data differently than HDDs, they require special techniques to extend the life of the drive, such as wear leveling support. Update the SSD's firmware. Newer firmware versions are released to fix bugs and optimize how the SSD stores data. Run a manufacturer-specific SSD software utility. Most SSD manufacturers have specialized utilities that can check for errors and optimize an SSD's performance. Check the speed of the SATA connection. Older SATA versions have slower transfer speeds than newer SATA versions. If performance is too slow, consider upgrading components to the latest SATA version. When the SSD is too full, performance will decrease significantly. If this happens, try enabling features such as TRIM support in the OS. While features such as TRIM will help to an extent, the best way to maintain high performance is keeping an SSD below 90% capacity. Failure to boot (OS not found) HDD/ SSD A failure to boot with an error message that reads something to the effect of "OS Not Found" could be trivial or serious. Common causes include the following: You're booting from the wrong disk that doesn't have an operating system installed. This is a very common issue. It frequently occurs when a CD or DVD is in your optical drive at system boot and the BIOS/UEFI is configured to boot from the optical drive first. The error message is displayed when an operating system can't be found on the optical disc. To fix this issue, simply remove the optical disc from the drive and reboot. This error could also be caused in situations where you have multiple hard disks in the system, but only one has an operating system installed. If the boot device setting gets inadvertently changed in the BIOS/UEFI, it will try to boot the system from the wrong hard disk. Your master boot record (MBR) has been overwritten or is corrupt. The MBR is the first sector of your hard drive that tells the BIOS where to look for the operating system on the disk. If the MBR is damaged or corrupt, then the operating system will fail to load. On Windows, you have to boot from the installation disc to enter the recovery environment and select the Automatic repair option. Alternatively, you can select the Command prompt option and run the bootrec command to rebuild the boot configuration data. You can also run the bootrec command with the following switches: o /fixmbr : Repairs the master boot record o /fixboot : Repairs the boot sector o /rebuildbcd : Rebuilds the boot configuration data Drive not recognized by the BIOS/UEFI HDD/SSD A modern BIOS/UEFI automatically detects your drives and their geometry during POST. In older systems, you had to manually enter the disk geometry, and it was very common for a wrong value to be entered. In modern systems, this rarely happens. If the BIOS can't detect your drive, it's usually caused by one of three things.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
