Dropping the 840 Evo in a secondary system and performing the update that way will kill the OS installation (Samsung only says this is due to a “Windows policy.

(Really? This is still a thing?)Īnd finally: If you need to update an 840 Evo with an OS installation on it, make sure you boot from that OS when you do the update.

Your PC will reboot 20 seconds after the procedure finishes.

Drives configured in RAID cannot be patched at this time.

RAID configurations are not supported.

Mac OS X and Linux patches are coming at an unspecified later date.

NTFS is the only file system supported.

Any custom storage driver can cause the procedure to fail, so fall back to Intel, AMD’s latest, or Microsoft standard - or hook the drive to one of these ports if you’re currently using a different class of controller (Asmedia, Marvell, etc). Samsung is to offer no less than five versions of the 840 EVO which includes a 120GB, 250GB, 500GB, 750GB and 1 TB models.

AMD’s latest chipset drivers can be downloaded here users also have the option to simply revert back to Microsoft’s AHCI driver before applying this patch. Samsung SSD 840 EVO Specifications and Features. Samsung notes that the “latest” AMD driver prevents this, but doesn’t actually give the driver version number. Firmware updates may fail if you are using an AMD drive controller.The application will not run unless at least 10% of the drive is free.Performance restoration will not work if a drive is locked with a user password or if TCG/Opal or Encrypted Drive standards are in place.Only MBR and GPT partitions are supported.Samsung has a list of 17 - here are some of the most important: When it comes to flashing a product, its always a good idea to read the instructions firmware updates remain one of the few ways to truly trash piece of equipment. The process is divided into three different steps and a progress bar is displayed at all times to display the status to you. When you start the Performance Restoration tool after the restart it will automatically start the optimization process. The Performance Restoration tool The caveats A restart of the PC is required after the update. This led to a quick succession of read cycles as the controller attempted to compensate, which substantially degraded performance. As the data in the cells got older (the 30-day window was something of a moving target), the drive had more trouble reading the information - what it expected to see and what it was actually seeing were two different things. The 840 Evo’s problem was that the calibration algorithm that’s supposed to detect the voltage levels in the cells apparently wasn’t calibrated correctly. Auto-refreshing the data with a periodic re-write isn’t an option - TLC NAND already has lower durability than other form factors, and a periodic background rewrite would quickly exhaust the number of program/erase (P/E) cycles. As time passes, the state shifts slightly and the drive has to compensate for that shift in order to read the older data. When data is written to triple-level (TLC) NAND, it’s stored at one of eight distinct voltage states. It turns out that the issue is a bug in how the drive calculates what the voltage level within a cell should be in order to perform a proper data read. Samsung has released its 840 Evo SSD repair tool, as well as additional information on what causes the problem.
